1. Ubuchwepheshe be-CVD obushisayo
Izembatho eziqinile ngokuvamile ziyizimbotshana ze-ceramic zensimbi (i-TiN, njll.), ezakhiwe ngokusabela kwensimbi ekufakweni nasekufakweni kwegesi esebenzayo.Ekuqaleni, ubuchwepheshe be-CVD obushisayo babusetshenziselwa ukuhlinzeka amandla okuqalisa wokusabela okuhlangene ngamandla ashisayo ekushiseni okuphezulu okungu-1000 ℃.Lokhu kushisa kulungele kuphela ukufaka i-TiN nezinye izinto eziqinile kumathuluzi e-carbide kasimende.Kuze kube manje, kusewubuchwepheshe obubalulekile ukufaka inhlanganisela ye-TiN-Al20 kumakhanda amathuluzi e-carbide ayindilinga.
2. I-ion ye-cathode engenalutho kanye ne-arc ion yocingo olushisayo
Ngawo-1980s, ukumbozwa kwe-ion cathode okungenalutho kanye ne-arc ion ion yocingo eshisayo kwasetshenziswa ukufaka amathuluzi okusika amboziwe.Bobabili lobu buchwepheshe bokuhlanganisa i-ion buwubuchwepheshe bokufaka i-arc discharge ion, ngezinga le-ionization yensimbi elifinyelela ku-20% ~ 40%.
3. I-cathode arc ion enamathela
Ukuvela kwe-cathodic arc ion coating kuye kwaholela ekuthuthukisweni kobuchwepheshe bokufaka ama-coatings aqinile ezibunjeni.Izinga le-ionization le-cathodic arc ion coating lingama-60% ~ 90%, okuvumela inani elikhulu lama-ion ensimbi kanye nama-ion egesi asabelayo ukuthi afinyelele indawo yokusebenza futhi aqhubeke nokusebenza okuphezulu, okuholela ekufakweni kokuphendula kanye nokwakheka kwezingubo eziqinile ezifana I-TiN.Njengamanje, ubuchwepheshe bokufaka i-cathodic arc ion coating busetshenziswa kakhulu ukufaka ama-coatings aqinile ezibunjeni.
Umthombo we-cathode arc ungumthombo wokuhwamuka kwesimo esiqinile ngaphandle kwechibi elincibilikisiwe elingaguquki, futhi indawo yomthombo we-arc ingabekwa ngokungafanele, ithuthukise izinga lokusebenzisa isikhala segumbi lokumboza futhi ikhulise umthamo wokulayisha isithando somlilo.Izimo zemithombo ye-cathode arc zihlanganisa imithombo emincane eyindilinga ye-arc ye-cathode, imithombo ye-columnar arc, kanye nemithombo eyisicaba eyisicaba emikhulu.Izingxenye ezihlukene zemithombo emincane ye-arc, imithombo ye-columnar arc, nemithombo emikhulu ye-arc ingahlelwa ngokuhlukana ukuze kufakwe amafilimu anezingqimba eziningi namafilimu e-nano multilayer.Phakathi naleso sikhathi, ngenxa yezinga eliphezulu le-ionization yensimbi ye-cathodic arc ion coating, ama-ion ensimbi angakwazi ukumunca amagesi amaningi okusabela, okuholela ezinhlobonhlobo zenqubo kanye nokusebenza okulula ukuze kutholakale ukunamathela okuhle kakhulu okuqinile.Kodwa-ke, kukhona amaconsi amaholo ku-microstructure yongqimba olunamathelayo olutholwe yi-cathodic arc ion coating.Eminyakeni yamuva, kuye kwavela ubuchwepheshe obuningi obusha ukuze kucwengisiswe ukwakheka kwesendlalelo sefilimu, okuye kwathuthukisa ikhwalithi yefilimu yokuhlanganisa i-arc ion.
