I roto i te whakatakotoranga kohu ā-tinana (PVD), ko te mātotoru o te kiriata tētahi o ngā tohu matua e whakatau ana i te mahi ā-mīhini, ā-whatu, ā-hiko, me te ātete ki te waikura o tētahi paninga. Mō ngā paninga mārō, ngā kiriata whakapaipai, ngā paninga whatu, me ngā kiriata angiangi mahi, ko te hanganga moroiti mātotoru e hono ana ki te piri pai ake, te pakeke ake, te iti ake o te porosity, me te ātete pai ake ki te kakahu me te pirau taiao.
Heoi, kāore te whakakīkī o te kiriata e whakatauhia mā te whakanui noa i te kaha whakatakoto, te tere whakatakoto rānei. I tōna pūtake, he hononga tata ki te mākī pūngao e tukuna ana ki te kiriata e tipu ana, e whakahaere ana i te nekenekehanga o te mata, te horapa o te adatom, te whanonga o te nucleation, te tipu o te witi, me te whanaketanga o ngā hapa i te wā whakatakoto.
Nō reira, he mea nui te mārama ki te whanaungatanga i waenga i te whakaurunga pūngao, te pupuhitanga katote, te pāmahana o te papa, me te hanganga moroiti o te kiriata hei arotau i ngā tukanga PVD.
1. He aha te Kīanga Pūngao i roto i te PVD?
I roto i te PVD, ko te kupu kiato pūngao e whakaahua ana i te nui o te pūngao e tukuna ana ki te papa, ki te kiriata tipu rānei mō ia wāhanga horahanga me roto i tētahi wā tukanga kua hoatu. I roto i te hangarau tukanga mahi, e hono tata ana ki ngā tawhā pēnei i te pūngao katote, te rerenga katote, te pānga papa, te kiato plasma, te mana tukunga, te tere whakatakotoranga, me te pāmahana papa.
Mō ngā tukanga PVD ionized, inā koa ko te whakatakotoranga pewa cathodic me te magnetron sputtering kaha-teitei, ka whakaatuhia te kiriata tipu ehara i te mea ki ngā momo whakatakotoranga kūpapa anake engari ki ngā katote pūngao hoki. Ina whakamahia he whakaaro tika mō te papa, ka tere ake ēnei katote ki te mata o te papa, ka whakawhiti i te pūngao ki te kiriata tipu.
Ka pā tēnei kaha whakauru ki te nekenekehanga o ngā ngota me ngā katote kua whakatakotoria ki runga i te mata. Mā te kaha rawaka ka taea e ngā adatom te wikitoria i ngā arai horapa ā-rohe, te heke ki ngā tūranga pai mō te kaha, me te whakakī i ngā āputa moroiti i roto i te kiriata e whanake ana. Nō reira, ka taea e te kiriata te whanake mai i tētahi hanganga porowhita ki tētahi hanganga moroiti kiato, kiato.
Nō reira, me whakaaro te mātotoru pūngao hei piriti nui i waenga i ngā tawhā tukanga PVD me te hanganga kiriata whakamutunga.
2. He aha te take e whakatau ai te whakaurunga pūngao i te kiato o te kiriata
I te wā tuatahi o te whakatakotoranga, kāore ngā ngota, ngā katote rānei e tae atu ana ki te paparanga e hanga tonu i tētahi paparanga kiato tino pai. Ka puta ake ō rātou pūngao ki te mata, ka heke, ā, ka āta hanga i ngā moutere ka honoa hei kiriata tonu.
Mena kāore i te rawaka te kaha nekeneke o ngā momo e tae mai ana, ka iti te nekenekehanga o te mata. Tērā pea ka noho tata tonu rātou ki ō rātou tūranga taunga tuatahi, ka hua ake he horapa koretake o te mata, ā, ka puta he āputa moroiti. I te haere tonu o te whakatakotoranga, ka taea e ēnei āputa te whanake hei hanganga moroiti poutū, he āhua pūwero.
He mea tino nui tēnei āhuatanga i roto i ngā tukanga whakatakotoranga pāmahana iti, i ngā pūnaha rānei e whakahaere ana me te kore e ranea te pupuhitanga katote.
Ina whakanuia te kaha e tukuna ana ki te kiriata e tipu ana ki tētahi taumata e tika ana, ka kaha ake te horapa o te mata. Ka taea e ngā momo kua whakatakotoria te heke puta noa i te mata, ka noho ki ngā tūranga iti iho te kaha, ko te pupuhi katote ka taea te whakatairanga i te whakaritenga anō o te ngota, te whakaiti i te hapa, me te katinga o te āputa. Ko te kiriata e hua ake ana he āhua matotoru ake, he hononga ā-mata kaha ake.
Mai i te tirohanga hanganga moroiti, ehara i te mea ko te "whakanui ake i te pūngao" anake te whāinga, engari ko te whakatū i te ōwehenga pūngao-ki-te rerenga e tika ana i te wā e tipu ana te kiriata.
3. Te Tūranga o te Pānga Papatūānuku
I roto i ngā tawhā tukanga PVD e wātea ana, ko te ngaohiko pīrori papa tētahi o ngā tikanga tino tika mō te whakahaere i te pūngao pupuhi katote.
Mā te whakamahi i te pānga kino ki te papa ka hangaia he pūmanawa hiko e whakateretere ana i ngā katote utu pai ki te mata o te papa. Ko te whakanui ake i te rahi o te pānga ka whakanui ake i te kaha pānga katote, ka taea te whakarei ake i te whakahohenga o te mata me te whakakīkī o te kiriata.
Hei tauira, i roto i te whakatakotoranga o TiN, CrN, TiAlN, DLC, me ētahi atu paninga mahi, ka taea e te āhua pāhekoheko tika te whakapai ake i te kiato kiriata, te pakeke, te piri, me te ātete ki te kakahu.
Heoi, kāore te hononga i waenga i te ngaohiko whakahāwea me te kounga o te kiriata i te rārangi. Mēnā ka nui rawa te kaha o te pupuhi katote, ka puta pea ētahi pānga kino, tae atu ki te reputtering, te whakaurunga, te kohikohinga ahotea toenga, te wera o te papa, te whakaputa hapa, tae atu ki te kino o te papa.
Ka taea hoki e te nui rawa o te pupuhi katote te tango i ngā ngota kua whakatakotoria i mua mai i te mata o te kiriata, ka whakaiti i te tere whakatakotoranga kupenga, ā, ka rerekē pea te hanganga paninga.
Nō reira, me whakatau te pānga pai rawa atu o te papa i runga anō i te rauemi o te papa, te pūnaha paninga, te momo katote, te mātotoru plasma, te tere whakatakotoranga, me ngā āhuatanga kiriata e hiahiatia ana, kaua e whai noa i te ngaohiko pānga teitei ake.
4. Me Whakaaro Ngātahi te Rerenga Ā-Iona me te Pūngao Ā-Iona
Ehara i te pūngao katote anake te mea e whakahaeretia ana te whakakīkī kiriata. He rite tonu te hiranga o te rerenga katote, arā, te maha o ngā katote e tae atu ana ki te papa mō ia wāhanga horahanga me te wā.
Ka taea e te rerenga katote pūngao-nui te whakarerekē nui i te kiriata e tipu ana, engari ki te iti rawa te rerenga katote, tera pea ka kore e ranea te pūngao katoa e whakawhitia ana ki te kiriata. I tetahi atu taha, ko te rerenga katote tino teitei i te nui rawa o te pūngao ka hua ake he pupuhi nui me te pupuhi anō kāore e hiahiatia, te uta wera rānei.
Nā konei, ko te whanaketanga o ngā tukanga PVD matatau e aro nui ana ki te whakahaere i te whanaungatanga i waenga i te kaha katote me te rerenga katote, kaua ki te aro ki te whakaaro ki te whakaaro o te pēhanga matū hei tawhā motuhake.
He mea tino nui tēnei whanaungatanga i roto i ngā tukanga whakatakoto ira-katote nui pērā i te cathodic arc PVD me te high-power impulse magnetron sputtering (HiPIMS). Mā te whakanui ake i te wāhanga ira-katote o te momo whakatakoto, ka whakaratohia e ēnei hangarau he ngāwari ake ki te whakahaere i te pūngao e tukuna ana ki te kiriata e tipu ana.
5. Te Kiato Pūngao me te Whanaketanga Hanganga Moroiti
Ka taea hoki te mārama ki te awe o te mātotoru o te pūngao mā te whanaketanga o te hanganga moroiti o te kiriata.
I raro i ngā āhuatanga whakatakotoranga iti te pūngao, ka taea e te nekehanga iti o te mata te arahi ki te tipu korekore, ki te tipu poutū rānei, inā koa ka iti te pāmahana o te papa, ā, kāore i te rawaka te nekehanga o ngā momo kua whakatakotoranga.
I te pikinga ake o te kaha e whakaurua ana i roto i tētahi matapihi tukanga e tika ana, ka nui ake te whai huatanga o te horapa o te mata, ā, ka āta piri haere te hanganga moroiti. Ka taea te whakaiti i ngā rohe kakano me ngā āputa i waenganui i ngā pou, i te mea ka mau tonu, ka pumau hoki te paninga.
Heoi, mā te pikinga ake o te mātotoru o te pūngao, ka taea e te tukanga te uru ki tētahi āhua e whakahaerehia ana e te pupuhi katote kaha. Ka piki haere te nui o te resputtering me te atomic peening, ka puta pea he ahotea toenga pēhi teitei. Ahakoa ka noho mātotoru tonu te paninga, ka taea e te ahotea ā-roto nui te whakaiti i te piri me te arahi ki te pakaru, ki te wehewehe rānei.
Nō reira, he matapihi tino pai te mātotoru o te pūngao, kaua ki tētahi hononga noa iho e hua ake ai he kiriata pai ake i te pūngao teitei ake.
6. Te Matū Pūngao me te Pānga "Te Whakapūtanga Atomika"
Ko tētahi o ngā tikanga nui e pā ana ki te pupuhitanga katote pūngao ko te pānga peening atomic.
I te wā e pupuhihia ana te kaha o te katote, ka whakawhitihia e ngā katote e tau mai ana te kaha ki ngā ngota o te mata, ka puta te nekehanga me te whakaritenga anō o te ngota o te rohe. Ka taea e tēnei te akiaki i ngā ngota ki ngā whirihoranga piripono ake, ā, ka pehi i te whanaketanga o te rōrahi tuwhera i roto i te kiriata e tipu haere ana.
Ko te mutunga iho ka nui ake te matotoru o te hanganga, ka nui ake te mārō me te pumau o te hangarau.
He mea tino nui tēnei tikanga mō ngā paninga PVD mārō. Mō ngā pūnaha pēnei i te TiN, CrN, TiCN, AlTiN, me ngā paninga nitride e pā ana, ka taea e te pupuhi katote tika te whai wāhi ki te kiato kiriata teitei me te whakapai ake i te mahi miihini.
Heoi anō, mā te nui rawa o te whāwhā ngota ka puta he ahotea toenga pēhanga nui. Nō reira, ehara i te mea ko te paninga he tino matotoru te paninga pai rawa atu mēnā ka nui ake tōna ahotea o roto i te kaha piri o te atanga papa/paninga.
Ko te whāinga mahi he whakatutuki i te taurite i waenga i te kiato kiriata, te ahotea toenga, te piri, te pakeke, me te tere whakatakotoranga.
7. Ka huri anō hoki te tere o te whakatakoto i te toenga pūngao
Kāore e taea te aromatawai i te mātotoru pūngao i runga i te tere whakatakotoranga.
Mena ka piki ake te tere o te whakatakoto i te mea kāore anō kia rerekē ngā āhuatanga o te pupuhi katote, ka heke pea te ōwehenga o te pupuhi katote kaha ki te rerenga whakatakoto e haere mai ana. Arā, he nui ake ngā rauemi e whakatakotoria ana me te kore he pikinga ōrite o te kaha e wātea ana hei whakatairanga i te horapa o te mata me te whakaritenga hanganga.
Ka hua ake pea tēnei i te nekehanga ki tētahi hanganga moroiti iti ake te kiato.
I tetahi atu taha, mā te pupuri i te ōwehenga rerenga katote-ki-kore e tika ana ka āwhina i te utu mō ngā huringa o te tere whakatakotoranga me te pupuri i te hanganga kiriata ōrite.
Koia te take me aro nui te whanaketanga o ngā tukanga PVD ahumahi ki te mana me te tere whakatakotoranga, engari ki te whanaungatanga hoki i waenga i te kiato o te iahiko katote, te kaha katote, te rerenga whakatakotoranga, me te pānga o te papa.
8. Ka Mahi Ngātahi te Pāmahana o te Papa me te Pāmatanga Ātona
Ko te pāmahana o te papa tētahi atu mea nui e pā ana ki te matotoru o te kiriata.
Mā te pūngao wera ka taea te nekeneke i ngā ngota kua whakatakotoria, ko te pupuhitanga katote ka taea te whakarato i te pūngao nekeneke tāpiri. Ka taea e ngā tikanga e rua te whakatairanga i te horapa o te mata me te whakaritenga hanganga.
Mō ngā papa e aro ana ki te pāmahana pērā i ngā kirihou hangarau, ngā wāhanga whatu, me ētahi rauemi hiko, kāore pea e taea te whakanui ake i te pāmahana o te papa. I ēnei wā, ka tino whai hua te pupuhi katote whakahaeretia nā te mea ka taea te whakarato i te pūngao tāpiri ki te kiriata e tipu ana me te kore e whakawhirinaki anake ki te whakamahana wera.
Koinei tētahi o ngā painga nui o ngā tukanga PVD āwhina-katote: ka taea te whakarei ake i te whakakīkī kiriata mā te pupuhi matūriki hihiko me te pupuri tonu i ngā pāmahana papa iti.
Ahakoa rā, ko te pupuhitanga katote tonu ka whakaputa wera. Nō reira, me aroturuki tonu te pāmahana o te papa puta noa i te tukanga whakatakoto hei ārai i te whakarerekētanga wera, te pirau rānei o ngā rauemi tairongo-pāmahana.
9. Me ōrite te mātotoru o te pūngao ki te pūnaha paninga
He rerekē ngā whakaritenga a ngā rauemi paninga mō te pupuhitanga katote me te whakaurunga pūngao.
Mō ngā paninga nitride mārō, he pai te whakamahi i te pupuhi katote kaha mō te whiwhi i te kiato teitei, te pakeke teitei, me te piri kaha. Mō ngā paninga whatu, mā te pupuhi nui ka puta he ahotea, ka whakarerekē rānei i te ōritetanga o te taupū whakaata. Mō ngā paninga whakapaipai whakarewa, mā te kaha nui o te kaha katote ka pā ki te āhua o te mata, te kanapa, te tae, me te ahotea toenga.
He tairongo ake ngā DLC me ētahi atu paninga waro ki te taurite i waenga i te kaha katote me ngā tikanga whakatakotoranga nā te mea ka taea e te kaha katote te awe i te whirihoranga hononga, nō reira ki te ōwehenga i waenga i te hononga sp² me te sp³.
Nō reira, kāore he "kiato pūngao tino pai" e tika ana mō ngā paninga PVD katoa. Me whakatū te matapihi tukanga tika i runga i te pūnaha rauemi, te papa, te matotoru o te kiriata, te tere whakatakotoranga, ngā āhuatanga miihini e hiahiatia ana, ngā whakaritenga whatu, me ngā herenga wera.
10. Mai i ngā Tawhā Tukanga ki te Mahi Kiriata
I roto i te hanga PVD ahumahi, me aromatawai te mātotoru pūngao mā roto i ngā āhuatanga kiriata ine, kaua mā roto i ngā tawhā tukanga anake.
Me whai wāhi te pūnaha whakauru pūngao kua tino arotauhia ki ngā whakapainga o te kiato kiriata, te pakeke, te piri, te ātete ki te kakahu, te ātete ki te waikura, te pumau whatu, me te mahi ārai, i runga i te tono.
Ka taea te whakamahi i ngā tikanga whakaahuatanga pēnei i te SEM whakawhiti-wāhanga, te XRD, te nanoindentation, te whakamātautau rakuraku, te ine ahotea toenga, te tātari taratara mata, me te mahere matotoru kiriata hei whakatū i te whanaungatanga i waenga i ngā tawhā tukanga me te mahi paninga.
Mā tēnei ka taea e te tukanga PVD te neke mai i te whakatikatika tawhā māmā ki tētahi matapihi tukanga pūnaha ake me te rautaki whakahaere hanganga moroiti.
Whakamutunga
I roto i te PVD, ko te mātotoru pūngao tētahi o ngā āhuatanga matua e whakahaere ana i te whakawhiti mai i ngā hanganga whakatakotoranga koretake ki ngā kiriata mātotoru, pumau hoki. Ka taea e te pūngao katote me te rere katote e tika ana te whakarei ake i te horapa o te mata, te whakatairanga i te whakaritenga ngota, te whakaiti i te hanganga āputa, me te whakapai ake i te mātotoru o te kiriata.
Heoi, kāore te kaha teitei e tohu aunoa i te pai ake o te mahi paninga. Mā te nui rawa o te pupuhi katote ka puta he resputtering, he wera o te papa, he ahotea toenga pēhanga teitei, me te kino o te atanga. Ko te mea nui ko te whakatū i tētahi taurite pai i waenga i te kaha katote, te rerenga katote, te tere whakatakotoranga, te pānga papa, te mātotoru plasma, me te pāmahana papa.
Nō reira, mō ngā taputapu PVD hou, ehara i te mea ko te kaha ki te whakahaere i te whakauru pūngao he huarahi noa iho ki te whakapiki i te pai o te whakatakotoranga—engari he kaha taketake mō te hanga hanganga kiriata moroiti me te whakatutuki i te mahi paninga pumau, ka taea te whakaputa anō.
