Iindlela eziqhelekileyo zokufaka iingubo eziqinileyo

1. Itekhnoloji ye-CVD yobushushu

Iingubo eziqinileyo ikakhulu ziingubo zesinyithi zeseramikhi (iTiN, njl.njl.), ezenziwe yimpendulo yesinyithi kwingubo kunye negesi esabelayo. Ekuqaleni, iteknoloji yeCVD yobushushu yayisetyenziselwa ukubonelela ngamandla okusebenza kwe-Combination reaction ngamandla obushushu kubushushu obuphezulu be-1000 ℃. Olu bushushu lufanelekile kuphela ekubekeni iTiN kunye nezinye iingubo eziqinileyo kwizixhobo ze-carbide ezifakwe isamente. Okwangoku, iseyiteknoloji ebalulekileyo yokufaka iingubo ze-TiN-Al2O3 ezihlanganisiweyo kwiintloko zezixhobo ze-carbide ezifakwe isamente.

1. Ingubo ye-ion ye-cathode engenanto kunye nengubo ye-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%.

1. Ugqunywe nge-arc ion ye-cathode

Ukuvela kwe-cathodic arc ion cating 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 we-solid-state ongenamanzi anyibilikisiweyo, 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 yezinga eliphezulu le-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 amancinci kwisakhiwo esincinci somaleko 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 i-arc ion.
