1. Itekhnoloji ye-CVD eshushu
Iingubo eziqinileyo ikakhulu ziingubo zesinyithi zeseramikhi (iTiN, njl.njl.), ezenziwe yimpendulo yesinyithi kwingubo kunye negesi esabelayo. Ekuqaleni, iteknoloji yeCVD yobushushu yayisetyenziselwa ukubonelela ngamandla okusebenza kwempendulo edibeneyo ngamandla obushushu kubushushu obuphezulu be-1000 ℃. Olu bushushu lufanelekile kuphela ekubekeni iTiN kunye nezinye iingubo eziqinileyo kwizixhobo ze-carbide ezifakwe isamente. Okwangoku, kuseyiteknoloji ebalulekileyo ukufaka iingubo zeTiN-Al20 ezihlanganisiweyo kwiintloko zezixhobo ze-carbide ezifakwe isamente.
2. Ugqunywe nge-ion ye-cathode engenanto kunye nogqunywe nge-ion ye-arc ye-wire eshushu
Kwiminyaka yoo-1980, i-hollow cathode ion coating kunye ne-hot wire arc ion coating zazisetyenziselwa ukufaka izixhobo zokusika ezigqunyiweyo. Zombini ezi teknoloji zokugqunywa kwee-ion ziiteknoloji zokugqunywa kwee-arc discharge ion coating, ezinezinga le-ionization yesinyithi elifikelela kwi-20% ~ 40%.
3. Ukwambathisa i-arc ion ye-cathode
Ukuvela kwe-cathodic arc ion coating kukhokelele ekuphuhlisweni kwetekhnoloji yokufaka ii-hard coating kwi-molds. Izinga le-ionization le-cathodic arc ion coating yi-60% ~ 90%, okuvumela inani elikhulu lee-metal ions kunye nee-reaction gas ions ukuba zifikelele kumphezulu we-workpiece kwaye ziqhubeke nokusebenza okuphezulu, okubangela ukufakwa kwe-reaction kunye nokwenziwa kwee-hard coating ezifana ne-TiN. Okwangoku, itekhnoloji ye-cathodic arc ion coating isetyenziswa kakhulu ukufaka ii-hard coating kwi-molds.
Umthombo we-cathode arc ngumthombo wokufuma wesimo esiqinileyo ongenalo ichibi elinyibilikisiweyo elizinzileyo, kwaye indawo yomthombo we-arc ingabekwa ngokungacwangciswanga, nto leyo ephucula izinga lokusetyenziswa kwendawo yegumbi lokugquma kunye nokwandisa amandla okulayisha esitovini. Iimilo zemithombo ye-cathode arc ziquka imithombo emincinci ye-arc ye-cathode ejikelezayo, imithombo ye-arc ye-columnar, kunye nemithombo ye-arc enkulu ethe tyaba. Izinto ezahlukeneyo zemithombo ye-arc encinci, imithombo ye-arc ye-columnar, kunye nemithombo emikhulu ye-arc zinokucwangciswa ngokwahlukeneyo ukuze kufakwe iifilimu ezinamaleko amaninzi kunye neefilimu ze-nano multilayer. Okwangoku, ngenxa yesantya esiphezulu se-ionization yesinyithi se-cathodic arc ion coating, ii-ion zesinyithi zinokufunxa iigesi ezininzi zokusabela, nto leyo ekhokelela kuluhlu olubanzi lwenkqubo kunye nokusebenza okulula ukufumana iingubo eziqinileyo ezintle. Nangona kunjalo, kukho amaconsi amakhulu kwisakhiwo se-microstructure yomaleko wokugquma ofunyenwe yi-cathodic arc ion coating. Kwiminyaka yakutshanje, kuye kwavela ubuchwepheshe obutsha obuninzi bokuphucula isakhiwo somaleko wefilimu, nto leyo eye yaphucula umgangatho wefilimu yokugquma ye-arc ion.
