Hoʻohana nui ʻia ka uhi ʻana o ka vacuum i nā ʻāpana kaʻa, nā mea ʻokiʻoki, nā ʻōmole, nā mea uila, nā lako hoʻonaninani, a me nā ʻoihana ʻē aʻe e hoʻomaikaʻi i ka hana o ka ʻili a me nā waiwai hana. I ka wā o ke kaʻina hana uhi ʻana, waiho ʻia kahi ʻili lahilahi ma luna o ka ʻili o ka substrate ma lalo o nā kūlana vacuum, e hana ana i kahi uhi hana me nā waiwai kikoʻī e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa ʻana i ka pala, ka haʻahaʻa haʻalulu, a i ʻole kahi hiʻohiʻona hoʻonaninani.
ʻO kahi nīnau maʻamau, inā paha e hoʻopilikia ka uhi ʻana i ka vacuum iā ia iho i ka paʻakikī o ka mea substrate. ʻAʻole pono ka pane. I ka hapa nui o nā noi, ʻo ke kumu nui o ka uhi ʻana i ka vacuum ka hoʻololi ʻana i nā waiwai o ka ʻili o ka workpiece ma mua o ka hoʻololi ʻana i nā waiwai mechanical nui o ka substrate. Eia nō naʻe, pili ka hopena maoli i ka ʻenehana uhi, ka mahana o ke kaʻina hana, ka mea substrate, ke ʻano hana uhi, a me nā palena o ke kaʻina hana.
1. Hoʻololi nui ka uhi ʻana o ka Vacuum i nā waiwai o ka ʻili
ʻO nā ʻenehana uhi hakahaka e like me PVD (Physical Vapor Deposition), PECVD (Plasma-Enhanced Chemical Vapor Deposition), a me nā kaʻina hana waiho hakahaka ʻē aʻe e hana i kahi ʻili hana lahilahi ma luna o ka ʻili substrate.
ʻAʻole e like me ka mālama wela nui, hiki ke hoʻololi nui i ke ʻano metallurgical a me nā waiwai mechanical o kahi mea ma o kona mānoanoa, ʻo ka uhi vacuum maʻamau e hoʻopilikia wale i ka papa ʻili. ʻO ka mānoanoa o ka uhi ʻana ma ka pae micrometer a i ʻole sub-micrometer, ma muli o ke kaʻina hana noi a me ka waiho ʻana.
No ka laʻana, hiki i nā uhi PVD paʻakikī e like me TiN, TiCN, CrN, TiAlN, a me AlTiN ke hāʻawi i ka paʻakikī o ka ʻili a me ke kūpaʻa o ka ʻaʻahu ma mua o ka substrate ma lalo. Eia naʻe, ʻaʻole kēia manaʻo ua loli ka paʻakikī o ka substrate holoʻokoʻa i ka nui like.
No laila, i ka loiloi ʻana i ka hopena o ka uhi hakahaka ma ka paʻakikī, he mea nui e hoʻokaʻawale ma waena o ka paʻakikī o ka substrate a me ka paʻakikī o ka uhi ʻana.
2. Hiki i ka uhi ʻana o PVD ke hoʻonui i ka paʻakikī o ka ʻili?
I nā noi he nui, hoʻohana kūikawā ʻia ka uhi ʻana o PVD e hoʻonui i ka paʻakikī o ka ʻili.
Hiki i nā uhi paʻakikī i waiho ʻia e nā kaʻina hana e like me ka hoʻoheheʻe ʻana o ke arc cathodic a me ka magnetron sputtering ke hana i nā ʻōnaehana uhi paʻa a paʻa loa me ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu maikaʻi loa.
No nā mea hana ʻokiʻoki, no ka laʻana, hiki i kahi uhi PVD paʻakikī ke hōʻemi i ka ʻaʻahu abrasive, ka ʻaʻahu pipili, a me ka friction ma ka interface tool-workpiece. Hana ka uhi ma ke ʻano he papa pale ʻili ʻoiai ke hāʻawi nei ka substrate i ka paʻa pono a me ke kākoʻo mechanical.
No laila, ʻaʻole i hoʻoholo ʻia ka hana hope loa e ka paʻakikī o ka uhi ponoʻī, akā, e ka hui pū ʻana o:
Paʻakikī o ke uhi ʻana + pipili o ke uhi ʻana + mānoanoa o ke uhi ʻana + paʻakikī o ka substrate + pilina o ke uhi ʻana/substrate + hoʻolālā o ke uhi ʻana.
ʻAʻole hiki i kahi uhi paʻakikī loa ke hōʻoiaʻiʻo koke i ka hana maikaʻi inā palupalu loa ke substrate a inā ʻaʻole lawa ka pipili o ka uhi.
3. E hoʻopilikia anei ka mahana o ka uhi ʻana i ka paʻakikī o ka substrate?
ʻO kēia kekahi o nā mea nui i ka loiloi ʻana inā paha e hoʻopilikia ka uhi ʻana i ka vacuum i ka paʻakikī o ka substrate.
Hana nā kaʻina hana PVD a me PECVD like ʻole i loko o nā pae mahana like ʻole. I ka wā o ka waiho ʻana, ua hōʻike ʻia ka substrate i ka ikehu wela i hana ʻia e ka plasma, ka hoʻopōkā ʻana o ka ion, nā kumu mahu, a i ʻole nā kūlana hana ʻē aʻe.
No nā mea i pili i ka hoʻomehana wela, ʻo ka nui o ka mahana o ka substrate a i ʻole ka hoʻomehana wela lōʻihi paha e hoʻopilikia i ka microstructure mua a me nā waiwai mechanical.
Eia kekahi laʻana, loaʻa i kekahi mau kila mea hana paʻakikī ko lākou mau waiwai mechanical ma o nā kaʻina hana quenching a me tempering kikoʻī. Inā ʻoi aku ka mahana o ka uhi ʻana ma mua o ka mahana tempering kūpono, aia kahi hiki ke loaʻa nā hopena tempering, kahi e hōʻemi ai i ka paʻakikī o ka substrate.
No laila, no nā kila paʻakikī a me nā mea ʻē aʻe e pili ana i ka wela, pono e hoʻolālā ʻia ke kaʻina hana uhi e like me ke kūlana mālama wela o ka mea a me ka mahana hana i ʻae ʻia.
4. Ka hoʻopā ʻana o ka Ion a me ka hoʻololi ʻana o ka ʻili
I nā kaʻina hana PVD he nui, ua hoʻokomo ʻia ka substrate i ka ion bombardment ma mua a i ka wā o ka waiho ʻana.
Hiki i ke kālai ʻana o ka ion a i ʻole ka hoʻomaʻemaʻe plasma ke wehe i nā mea haumia o ka ʻili a hoʻoulu i ka ʻili substrate, e hoʻomaikaʻi ana i ka hoʻopili ʻana o ka uhi. I ka wā o ka waiho ʻana, hiki i ka hoʻopōʻino ion i kāohi ʻia ke hoʻopilikia i ka densification o ka kiʻiʻoniʻoni, ke koena o ke kaumaha, ka microstructure, a me ka hoʻopili ʻana o ka uhi.
Eia nō naʻe, ʻo ka nui o ka ikehu ion a i ʻole nā palena hana kūpono ʻole paha e hana i nā hopena maikaʻi ʻole e like me ka hoʻomehana nui ʻana o ka substrate, ka hōʻino ʻana o ka ʻili, a i ʻole ka hoʻonui ʻia o ke koʻikoʻi koena.
No laila, pono e hoʻomalu pono ʻia nā palena e like me ke voltage bias, ke au arc, ka mana hoʻokuʻu, ke kaomi hana, ka mahana o ka substrate, a me ka helu deposition e like me ka mea substrate a me ka ʻōnaehana uhi.
5. He ʻokoʻa ka paʻakikī o ka uhi ʻana mai ka paʻakikī o ka substrate
ʻO kahi kuhi hewa maʻamau, ʻo ia ka lilo ʻana o kahi ʻāpana hana i "paʻakikī" no ka mea ua waiho ʻia kahi uhi paʻakikī ma luna o kona ʻili.
ʻO ka ʻoiaʻiʻo, hana ka uhi ʻana i kahi ʻili paʻakikī i ka uhi ʻana o ka vacuum, ʻoiai ʻo ka paʻakikī o ka substrate e hoʻoholo nui ʻia e ke ʻano o kona mea mua a me ka mālama wela.
Eia kekahi laʻana, loaʻa paha i kahi mea ʻoki carbide kahi substrate paʻakikī a me kahi uhi PVD paʻakikī aʻe. Hoʻomaikaʻi ka uhi ʻana i ke kūpaʻa ʻana o ka ʻili a me ka hana tribological, ʻoiai ʻo ka substrate carbide e hāʻawi i ka ikaika a me ke kūpaʻa o ke kūkulu ʻana.
Pēlā nō, no nā ʻāpana kila paʻakikī, hiki i ka uhi PVD ke hāʻawi i kahi ʻili paʻakikī a ʻoi aku ka pale ʻana i ke komo ʻana me ka ʻole o ka hoʻololi nui ʻana i ka paʻakikī o ke kila ma lalo, inā e noho mau ka mahana waiho ʻana i loko o ka puka makani hana kūpono.
6. Pehea e pale aku ai i ka uhi ʻana o ka Vacuum mai ka hoʻopilikia ʻana i ka paʻakikī o ka substrate
No ka mālama ʻana i nā waiwai mechanical mua o ka substrate, pono e hoʻomaikaʻi ʻia ke kaʻina hana uhi e like me ka mea a me ka noi.
ʻO ka mea mua, pono e hōʻoia i ka mea substrate a me ke kūlana mālama wela ma mua o ka uhi ʻana. ʻOkoʻa nā palena wela o nā papa like ʻole o ke kila kila, ke kila kila, ka carbide, nā mea hoʻohuihui alumini, a me nā mea ʻē aʻe.
ʻO ka lua, pono e kāohi ʻia ka mahana o ka uhi ʻana i loko o kahi pae kūpono. No nā mea e pili ana i ka wela, hiki ke koho ʻia kahi PVD haʻahaʻa wela a i ʻole ke kaʻina hana waiho kūpono ʻē aʻe.
ʻO ke kolu, pono e hoʻomaikaʻi ʻia nā ʻōnaehana hana e like me ke anakahi uila, ka ikehu ion, ka nui o ka plasma, ka helu hoʻokaʻawale ʻana, ke kaomi hana, a me ka manawa hana e hoʻokō ai i ka hana uhi i koi ʻia me ka ʻole o ka hopena wela a i ʻole ka hopena ion.
ʻO ka mea hope loa, pono e loiloi ʻia nā ʻāpana i uhi ʻia ma o nā hoʻāʻo kūpono, me ka hoʻāʻo ʻana o ka microhardness, ka hoʻāʻo ʻana i ka hoʻopili ʻana o ka uhi, ka hoʻāʻo ʻana i ke komo ʻana, ke ana ʻana o ka ʻili, a me ka nānā ʻana i ka metallographic, ma muli o ka noi.
7. Hopena
No laila, pili anei ka uhi ʻana i ka vacuum i ka paʻakikī o ka mea?
Ma keʻano laulā, ʻo ka uhi ʻana i ka vacuum he hana ʻenekinia ʻili nui ia a ua hoʻolālā ʻia e hoʻololi i nā waiwai o ka ʻili o kahi mea ma mua o ka hoʻololi nui ʻana i kona paʻakikī nui. Hiki i nā uhi PVD paʻakikī ke hoʻomaikaʻi nui i ka paʻakikī o ka ʻili, ke kūpaʻa ʻana i ke kapa, ke ʻano friction, ke kūpaʻa ʻana i ka corrosion, a me ke ola lawelawe ʻoiai e mālama ana i nā waiwai mechanical o ka substrate.
Eia nō naʻe, hiki ke hoʻopilikia ʻia ka paʻakikī mua o ka substrate inā hoʻolauna ke kaʻina hana uhi i ka nui o ka hoʻomehana wela a i ʻole ka hoʻouka ʻana o ka ion kūpono ʻole, ʻoi aku hoʻi no nā kila i mālama ʻia i ka wela a me nā mea ʻē aʻe e pili ana i ka mahana.
No laila, he mea nui ke koho ʻana i ka ʻenehana hoʻokomo vacuum kūpono, ka mea uhi, ka mahana o ka substrate, nā kūlana hoʻopōkā ion, a me nā palena hana.
Me ka puka makani hana kūpono a me ka hoʻonohonoho ʻana o nā lako, hiki i ka uhi ʻana o ka vacuum ke hoʻokō i ka hui like i makemake ʻia o ka paʻakikī o ka ʻili kiʻekiʻe, ka hoʻopili ʻana o ka uhi ikaika, ke kūpaʻa ʻaʻahu maikaʻi loa, a me nā waiwai substrate paʻa, e hāʻawi ana i kahi hopena ʻenekinia ʻili kūpono no nā noi ʻoihana koi.
