- Ubuchwepheshe be-CVD obushisayo
Izembatho eziqinile ngokuvamile ziyizimbotshana ze-ceramic zensimbi (i-TiN, njll.), ezakhiwe ngokusabela kwensimbi ekufakweni nasekufakweni kwegesi okusebenzayo. Ekuqaleni, ubuchwepheshe be-CVD obushisayo babusetshenziselwa ukuhlinzeka amandla okuqalisa we-Combination reaction by thermal energy at izinga lokushisa eliphezulu elingu-1000 ℃. Lokhu kushisa kulungele kuphela ukufaka i-TiN nezinye izinto eziqinile kumathuluzi e-carbide kasimende. Kuze kube manje, kusewubuchwepheshe obubalulekile bokufaka inhlanganisela ye-TiN – Al2O3 kumakhanda amathuluzi e-carbide anosimende.
- I-ion 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 be-arc discharge ion coating, ngezinga le-ionization yensimbi elifinyelela ku-20% ~ 40%.
- I-cathode arc ion coating
Ukuvela kwe-cathodic arc ion cating 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 nama-ion egesi asabelayo ukuthi afinyelele phezu kwendawo yokusebenza futhi aqhubeke nokusebenza okuphezulu, okuholela ekufakweni kokusabela kanye nokwakheka kwezingubo eziqinile njenge-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-micro-structure ye-coating layer etholwe 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.
