- Itekhnoloji ye-Thermal CVD
Iingubo ezilukhuni ziyintsimbi ye-ceramic (i-TiN, njl.), ezenziwe ngokusabela kwesinyithi kwi-coating kunye ne-gasification esebenzayo. Ekuqaleni, itekhnoloji ye-Thermal CVD yayisetyenziselwa ukubonelela amandla okusebenza okuHlanganisa ukusabela ngamandla obushushu kubushushu obuphezulu be-1000 ℃. Eli qondo lobushushu lilungele kuphela ukufaka i-TiN kunye nezinye iingubo eziqinileyo kwizixhobo ze-carbide zesamente. Ukuza kuthi ga ngoku, kusebuchwephesha obubalulekileyo bokufaka i-TiN - i-Al2O3 yokwambathisa ehlanganisiweyo kwiintloko zezixhobo ze-carbide ezisamente.
- Ukwaleka kwe-ion ye-cathode kunye ne-arc ion yocingo eshushu
Ngeminyaka yoo-1980, i-cathode ion coating kunye ne-arc ion yocingo eshushu yasetyenziswa ukufaka izixhobo zokusika ezigqunyiweyo. Zombini ezi teknoloji zokugquma i-ion ziyi-arc discharge ion tekhnoloji yokwaleka, kunye nesantya se-ionization yesinyithi ukuya kuthi ga kwi-20% ~ 40%.
- Cathode arc ion ukutyabeka
Ukuvela kwe-cathodic arc ion cating kuye kwakhokelela ekuphuhlisweni kobuchwephesha bokubeka iingubo ezinzima kwiimbumba. Izinga le-ionization ye-cathodic arc ion coating yi-60% ~ 90%, evumela ukuba inani elikhulu leeyoni zetsimbi kunye ne-ion yegesi yokusabela ukuba ifikelele kumphezulu we-workpiece kwaye igcine umsebenzi ophezulu, okukhokelela ekufakweni kwe-reaction kunye nokwakhiwa kwee-coatings ezinzima ezifana ne-TiN. Okwangoku, itekhnoloji yokugquma i-cathodic arc ion isetyenziswa ikakhulu ukufaka ii-coatings eziqinileyo kwi-mold.
Umthombo we-arc we-cathode ngumthombo we-solid-state evaporation ngaphandle kwe-pool edibeneyo etyhidiweyo, kwaye indawo yomthombo we-arc inokubekwa ngokungekho mthethweni, ukuphucula izinga lokusetyenziswa kwendawo yegumbi lokugquma kunye nokwandisa amandla okulayisha eziko. Imilo yemithombo ye-arc ye-cathode ibandakanya imithombo encinci ye-arc ye-cathode ye-arc, imithombo ye-columnar arc, kunye nemithombo ye-arc enkulu ye-rectangular. Amacandelo ahlukeneyo emithombo emincinci ye-arc, imithombo ye-columnar arc, kunye nemithombo emikhulu ye-arc inokulungiswa ngokwahlukileyo ukuze ifake iifilimu ze-multi-layer kunye ne-nano multilayer films. Okwangoku, ngenxa yomgangatho ophezulu we-ionization yesinyithi ye-cathodic arc ion coating, ii-ion zetsimbi zinokufunxa iigesi eziphendulayo ezingaphezulu, okukhokelela kuluhlu olubanzi lwenkqubo kunye nokusebenza okulula ukufumana i-coatings egqwesileyo enzima. Nangona kunjalo, kukho amathontsi arhabaxa kwi-micro-structure ye-coating layer efunyenwe yi-cathodic arc ion coating. Kwiminyaka yakutshanje, ubugcisa obuninzi obutsha buye bavela ukuze kuphuculwe isakhiwo sefilimu, eye yaphucula umgangatho wefilimu yokugqoka i-arc ion.
