Pamene kupanga kwamakono kukupitilira kufunafuna magwiridwe antchito apamwamba kuchokera kuzinthu zina, makamaka zomwe zimagwira ntchito pansi pamikhalidwe yovuta kwambiri monga kutentha kwambiri, kupanikizika kwambiri, ndi kukangana kwakukulu, ukadaulo wopaka utoto wakula kwambiri. Kugwiritsa ntchito zokutira zolimba kumakhala ndi gawo lalikulu pakukulitsa kulimba kwa zida, kulondola kwa makina, komanso magwiridwe antchito onse. Ukadaulo wa PVD (Physical Vapor Deposition) ndiwotsogola pantchito yatsopanoyi, ndikupititsa patsogolo luso lazopaka utoto.
No.1 Kodi PVD Process ndi chiyani?
Dongosolo la PVD limaphatikizapo kugwiritsa ntchito njira zakuthupi kuti asinthe zinthu zokutira kuchokera pamalo olimba kapena amadzimadzi kukhala mpweya wa mpweya, kenako ndikuziyika pagawo laling'ono podutsa mpweya kuti zipange zokutira yunifolomu, zolimba komanso zolimba. Poyerekeza ndi chikhalidwe cha mankhwala vapor deposition (CVD), ubwino waukulu wa PVD ndi kuthekera kwake kuyika zokutira pa kutentha kochepa, kuwongolera ndendende makulidwe ndi kapangidwe kake, komanso chilengedwe chake chokonda zachilengedwe komanso chosagwiritsa ntchito mphamvu.
No.2 Ubwino wa PVD mu Zopaka Zolimba
Chifukwa cha ubwino wake wapadera, teknoloji ya PVD imadziwika kwambiri pogwiritsira ntchito zokutira zolimba, makamaka m'madera omwe amafunikira kuuma kwakukulu, kukana kuvala bwino, komanso kukana kwa dzimbiri kwapamwamba. Ubwino waukulu wa njira ya PVD ndi:
1. Ultra-high Kuuma ndi Kuvala Kukaniza
PVD zokutira zolimba zimakulitsa kwambiri kuuma kwa chigawocho. Poika zinthu monga TiN (Titanium Nitride), TiAlN (Titanium Aluminium Nitride), ndi CrN (Chromium Nitride), kulimba kwa zokutira kumatha kufika 25GPa-63GPa kapena kupitilira apo. Zovala zolimbazi zimathandizira bwino kukana kuvala, kuchepetsa kuphulika kwa pamwamba, kumawonjezera kukana kwa okosijeni, ndikukulitsa moyo wautumiki wa zida, nkhungu, ndi zinthu zina.
2. Zabwino Kwambiri Kutentha Kwambiri Kukaniza
Zovala za PVD zimawonetsa kukana kutentha kwambiri, zomwe zimawapangitsa kukhala abwino pazinthu zomwe zimatentha kwambiri komanso kukangana kwakukulu kapena dzimbiri lamankhwala. Mwachitsanzo, zokutira za TiAlN sizimangopereka kuuma kwapadera komanso zimasunga bata pamatenthedwe okwera, zomwe zimawapangitsa kuti azigwiritsidwa ntchito kwambiri podulira zida ndi nkhungu zopangira makina otentha kwambiri.
3. Low Friction Coefficient for Kupititsa patsogolo Machining Mwachangu
Zopaka za PVD zimathandizira kukwaniritsa ma ultra-low friction coefficients, kuchepetsa mikangano yakuthupi ndi kuvala, zomwe zimapangitsa kuti makina azigwira bwino ntchito komanso mawonekedwe apamwamba. Izi ndizopindulitsa makamaka pakukonza makina olondola komanso njira zodula kwambiri.
4. Kusamalidwa ndi chilengedwe komanso Mwachangu
Poyerekeza ndi njira zachikhalidwe zokutira, njira ya PVD simafuna mankhwala owopsa, zomwe zimapangitsa kuti ikhale luso losunga zachilengedwe. Kuphatikiza apo, zida zokutira za PVD zimagwira ntchito bwino kwambiri, zomwe zimathandizira kuyika mwachangu kuti zikwaniritse zofunikira zopanga zazikulu.
Na.3 Minda Yogwiritsira Ntchito PVD Yopaka Yolimba
PVD Hard Coating makina opangira zokutira zolimba amagwiritsidwa ntchito kwambiri m'mafakitale omwe amafunikira magwiridwe antchito apamwamba. Magawo ena ofunikira ogwiritsira ntchito ndi awa:
1. Kudula Zida ndi Nkhungu
Popanga zida ndi nkhungu, makamaka zida zodulira zomwe zimawonekera kutentha kwambiri ndi kukangana, zokutira za PVD zimakulitsa kwambiri kukana, kukana dzimbiri, komanso kuuma. Zovala za TiN zimagwiritsidwa ntchito kwambiri potembenuza zida, zodula mphero, ndi kubowola, pomwe zokutira za TiAlN zimagwiritsidwa ntchito kwambiri pakugwiritsa ntchito mothamanga kwambiri, kumathandizira kwambiri kudula zida komanso moyo wautumiki.
2. Zida Zagalimoto
Pazigawo zamainjini zamagalimoto monga masilinda, ma pistoni, ndi mavavu, zokutira zolimba za PVD zimapereka kukana kutentha kwambiri komanso kukana kuvala, kuchepetsa mikangano, kukulitsa moyo wazinthu, komanso kupititsa patsogolo magwiridwe antchito agalimoto.
4. Kuyambitsa Zhenhua FMA0605 PVD Zida Zopangira Zolimba
Ubwino wa Zida
Kusefedwa koyenera kwa arc macro-particles; Zovala za Ta-C zimapereka magwiridwe antchito apamwamba komanso magwiridwe antchito apamwamba.
Imakwaniritsa kuuma kopitilira muyeso, zokutira zolimba kwambiri zosatentha kwambiri, kugundana kocheperako, komanso kukana kwa dzimbiri. Kuuma kwapakati kumafika 25GPa-63GPa.
Cathode imagwiritsa ntchito ukadaulo wamagalimoto apawiri kuphatikiza koyilo yakutsogolo ndi stacking yokhazikika ya maginito, imagwira ntchito limodzi ndi makina a ion etching ndi mawonekedwe atatu amitundu ingapo kuti akwaniritse bwino.
Okonzeka ndi lalikulu m'mimba mwake cathodic arc, amene amaonetsetsa kwambiri kuzirala katundu pansi pa mkulu panopa. Kuthamanga kwa malo a arc ndikothamanga, kutsika kwa ionization ndikwambiri, ndipo kutsika kumathamanga. Izi zimathandizira kuyika kwa zokutira zowuma komanso zosalala zokhala ndi kukana kwa okosijeni wapamwamba komanso kutentha kwambiri.
Kuchuluka kwa Ntchito:
Zidazi zimatha kuyika AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, ndi zokutira zina zolimba kwambiri zosatentha kwambiri, zomwe zagwiritsidwa ntchito kwambiri mu nkhungu, zida zodulira, nkhonya, zida zamagalimoto, ma pistoni, ndi zinthu zina.
