Sezvo kugadzira kwemazuva ano kuri kuramba kuchida mashandiro akakwirira kubva kuzvikamu, kunyanya izvo zvinoshanda mumamiriro ezvinhu akaoma akadai sekupisa kwakanyanya, kumanikidzwa kwakanyanya, uye kukweshana kwakasimba, tekinoroji yekuputira yave kukosha zvakanyanya. Kushandiswa kwezvipfeko zvakasimba kunoita basa guru mukusimudzira kugara kwenguva refu kwezvishandiso, kunyatsogadzira michina, uye kushanda zvakanaka kwechigadzirwa chose. Tekinoroji yekurapa pamusoro pePVD (Physical Vapor Deposition) ndiyo iri pamberi pekuvandudzwa kwehunyanzvi munzvimbo iyi, ichitungamira kufambira mberi muhunyanzvi hwekuputira.
Nhamba 1 Chii chinonzi PVD Process?
Maitiro ePVD anosanganisira kushandisa nzira dzepanyama kushandura zvinhu zvekufukidza kubva pachimiro chakasimba kana chemvura kuita chimiro chegasi, wozozviisa pamusoro pe substrate kuburikidza nekuiswa kwemhepo kuti zvigadzire chipfeko chakafanana, chakaoma, uye chinogara kwenguva refu. Kana tichienzanisa nekushandiswa kwemakemikari ekuputira kwemhepo (CVD), mabhenefiti makuru ePVD ari mukukwanisa kwayo kuisa machira patembiricha yakaderera, kudzora ukobvu hwemachira nekuumbwa kwawo, uye hunhu hwayo husingakuvadzi nharaunda uye husingadyi simba zvakanyanya.
Nhamba 2 Mabhenefiti ePVD muHard Coatings
Nekuda kwezvakanaka zvayo zvakasiyana, tekinoroji yePVD inozivikanwa zvakanyanya mukushandisa machira akaomarara, kunyanya munzvimbo dzinoda kuomarara kwakanyanya, kuramba kupfeka zvakanaka, uye kuramba ngura zvakanyanya. Zvakanakira zvikuru zvemaitiro ePVD zvinosanganisira:
1. Kuomarara kwakanyanya uye Kuramba Kupfeka
Mapurasitiki akaomarara ePVD anowedzera kuomarara kwezvikamu. Nekuisa zvinhu zvakaita seTiN (Titanium Nitride), TiAlN (Titanium Aluminum Nitride), uye CrN (Chromium Nitride), kuomarara kwepurasitiki kunogona kusvika 25GPa–63GPa kana kupfuura. Mapurasitiki akaomarara aya anonyatso vandudza kusakara, anoderedza kukweshana kwepadenga, anowedzera kusachena, uye anowedzera hupenyu hwebasa rezvishandiso, mapundu, nezvimwe zvikamu.
2. Kuramba Kwakanaka Kwekupisa Kwakakwirira
Mapendi ePVD anodzivirira kupisa kwakanyanya, zvichiita kuti akwanise kushandiswa muzvinhu zvinopisa zvakanyanya uye zvinokanganisa ganda zvakanyanya kana kuti zvinoora nemakemikari. Semuenzaniso, mapendi eTiAlN haangopi chete kuoma kwakanyanya asiwo anochengetedza kugadzikana kwechimiro pakupisa kwakanyanya, zvichiita kuti ashandiswe zvakanyanya mukucheka maturusi uye maforoma ekushandisa mukugadzira machining pakupisa kwakanyanya.
3. Kushanda Kwakaderera Kwekukweshana Kwebasa Kuti Kushandiswe Pakugadzira Machining Kuve Nekubudirira
Mapurasitiki ePVD anobatsira kuwana ma coefficients ekukweshana akaderera zvakanyanya, zvichideredza kukweshana kwezvinhu uye kupera, izvo zvinowedzera kushanda zvakanaka kwemuchina uye kunaka kwenzvimbo yacho. Izvi zvinobatsira zvikuru pakugadzira nemazvo uye kucheka nekukurumidza.
4. Inogarika uye Inoshanda Zvikuru
Kana tichienzanisa nemaitiro echinyakare ekuputira, maitiro ePVD haadi makemikari akawanda anokuvadza, zvichiita kuti ive tekinoroji isingakuvadzi nharaunda. Pamusoro pezvo, michina yekuputira yePVD inoshanda zvakanaka, zvichiita kuti kuiswa kwayo nekukurumidza kusvike pazvinodiwa pakugadzirwa kukuru.
Nhamba 3 Minda yekushandiswa yePVD Hard Coating
Michina yePVD Hard Coating ye hard coating inoshandiswa zvakanyanya mumaindasitiri anoda kushanda kwepamusoro-soro. Dzimwe nzvimbo dzakakosha dzekushandisa dzinosanganisira:
1. Zvishandiso zveKucheka neMakumbo
Mukugadzira zvishandiso neforoma, kunyanya zvezvishandiso zvekucheka zvinosangana nekupisa kwakanyanya uye kukweshana, maPVD coatings anowedzera zvakanyanya kuramba kupfeka, kuramba ngura, uye kuomarara. MaTiN coatings anowanzo shandiswa mukushandisa maturusi ekutenderedza, magayira, uye mabhora, nepo maTiAlN coatings achishandiswa zvakanyanya mukushandisa maturusi ekukurumidzira, zvichivandudza zvikuru kushanda zvakanaka kwezvishandiso uye hupenyu hwebasa.
2. Zvikamu zveMotokari
Kune zvikamu zveinjini dzemotokari zvakaita semasirinda, mapistoni, nemavharuvhu, maPVD hard coating anopa simba rakanaka rekudzivirira kupisa kwakanyanya uye kusakara, zvichideredza kukweshana, kuwedzera hupenyu hwezvikamu, uye kuwedzera mashandiro emotokari.
4. Kusuma Zhenhua FMA0605 PVD Hard Coating Equipment
Zvakanakira Midziyo
Kusefa zvakanaka kwema arc macro-particles; machira eTa-C anopa zvese kushanda zvakanaka uye kushanda zvakanaka.
Inoomesa zvakanyanya, inovhara zvakasimba zvisingatsvi zvakanyanya, ine simba shoma rekukweshana, uye inodzivirira ngura zvakanyanya. Avhareji yekuoma kwayo inosvika 25GPa–63GPa.
Cathode inoshandisa tekinoroji ine madhiraivha maviri inosanganisa coil iri pamberi uye permanent magnet stacking, ichishanda pamwe chete ne ion etching system uye three-dimensional multi-angle fixture kuti iwane nzvimbo inoshanda.
Yakashongedzerwa ne arc yakakura ine dhayamita cathodic, iyo inoita kuti kutonhora kutonhorere zvakanaka mumamiriro ekunze ane simba guru. Kumhanya kwekufamba kwenzvimbo ye arc kunokurumidza, ionization rate yakakwira, uye deposition rate inokurumidza. Izvi zvinogonesa deposition ye denser uye yakapfava ine resistance yepamusoro ye oxidation uye performance yepamusoro-soro.
Mashandisirwo Ekushandisa:
Midziyo iyi inogona kuisa AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, nedzimwe mbatya dzakasimba dzisingapise kupisa kwakanyanya, idzo dzakashandiswa zvakanyanya muzviumbwa, maturusi ekucheka, zvibhakera, zvikamu zvemotokari, mapistoni, nezvimwe zvigadzirwa.
