1. Ubuchwepheshe be-CVD obushisayo
Izimbozo eziqinile ikakhulukazi ziyimbozo zensimbi ze-ceramic (i-TiN, njll.), ezakhiwa ukusabela kwensimbi ekumbozweni kanye ne-reactive gasification. Ekuqaleni, ubuchwepheshe be-thermal CVD basetshenziswa ukuhlinzeka ngamandla okusebenza okusabela okuhlangene ngamandla okushisa ekushiseni okuphezulu okungu-1000 ℃. Lokhu kushisa kufaneleka kuphela ekufakeni i-TiN nezinye izimbozo eziqinile kumathuluzi e-carbide aqinisiwe. Kuze kube manje, kusewubuchwepheshe obubalulekile ukufaka izimbozo ze-TiN-Al20 ezihlanganisiwe emakhanda amathuluzi e-carbide aqinisiwe.
2. Ukugqoka kwe-ion ye-cathode engenalutho kanye nokugqoka kwe-ion ye-arc ye-wire eshisayo
Ngawo-1980, i-hollow cathode ion coating kanye ne-hot wire arc ion coating kwakusetshenziswa ukufaka amathuluzi okusika ambozwe nge-coating. Zombili lezi zobuchwepheshe ze-ion coating ziwubuchwepheshe be-arc discharge ion coating, ngesilinganiso se-ionization sensimbi esifinyelela ku-20% ~ 40%.
3. Ukwembozwa kwe-ion ye-arc ye-cathode
Ukuvela kwe-cathodic arc ion coating kuholele ekuthuthukisweni kobuchwepheshe bokufaka i-hard coating kuma-mold. Izinga le-ionization le-cathodic arc ion coating lingu-60% ~ 90%, okuvumela inani elikhulu lama-metal ion nama-reaction gas ion ukuthi afinyelele phezulu kwe-workpiece futhi aqhubeke nokusebenza okuphezulu, okuholela ekufakweni kwe-reaction kanye nokwakheka kwe-hard coating njenge-TiN. Njengamanje, ubuchwepheshe be-cathodic arc ion coating busetshenziswa kakhulu ukufaka i-hard coating kuma-mold.
Umthombo we-cathode arc ungumthombo wokuhwamuka kwesimo esiqinile ongenalo ichibi elincibilikisiwe eliqinile, futhi indawo yomthombo we-arc ingabekwa ngokungahleliwe, kuthuthukiswe izinga lokusetshenziswa kwesikhala segumbi lokumboza futhi kwandiswe umthamo wokulayisha wesithando. Izimo zemithombo ye-cathode arc zifaka imithombo emincane ye-cathode arc eyindilinga, imithombo ye-columnar arc, kanye nemithombo emikhulu ye-arc eyisicaba engunxande. Izingxenye ezahlukene zemithombo emincane ye-arc, imithombo ye-columnar arc, kanye nemithombo emikhulu ye-arc zingahlelwa ngokwehlukana ukuze kufakwe amafilimu anezingqimba eziningi namafilimu e-nano multilayer. Okwamanje, ngenxa yesilinganiso esiphakeme se-ionization yensimbi se-cathodic arc ion coating, ama-ion ensimbi angamunca amagesi amaningi okusabela, okuholela ebangeni lenqubo ebanzi kanye nokusebenza okulula ukuthola izingqimba eziqinile ezinhle kakhulu. Kodwa-ke, kunezinhlayiya ezincane esakhiweni esincane sengqimba yokumboza etholwe yi-cathodic arc ion coating. Eminyakeni yamuva nje, kuye kwavela ubuchwepheshe obusha obuningi bokulungisa isakhiwo sengqimba yefilimu, okuthuthukise ikhwalithi yefilimu yokumboza i-arc ion.
