Ezi ngubo ziqinileyo ziphucula ngempumelelo ukuxhathisa ukuguguleka, zinciphise ukurhawuzelelwa komphezulu, zonyusa ukuxhathisa ukubola, kwaye zandisa ubomi benkonzo yezixhobo, iimolds, kunye nezinye izinto.
2. Ukumelana okugqwesileyo kobushushu obuphezulu
Iingubo zePVD zinokumelana okubalaseleyo nobushushu obuphezulu, nto leyo eyenza ukuba zilungele izinto eziphantsi kobushushu obuphezulu kunye nokungqubana okuphezulu okanye ukubola kweekhemikhali. Umzekelo, iingubo zeTiAlN aziboneleli nje kuphela ngobunzima obungaqhelekanga kodwa zigcina uzinzo lwesakhiwo kumaqondo obushushu aphezulu, nto leyo eyenza ukuba zisetyenziswe kakhulu kwizixhobo zokusika kunye neenkuni kwizicelo zoomatshini bokushisa obuphezulu.
3. I-Coefficient ephantsi yokuHlanganisa ukuze kuphuculwe ukusebenza kakuhle kweMishini
Iingubo zePVD zinceda ekufezekiseni ii-coefficients zokungqubana eziphantsi kakhulu, zinciphisa ukungqubana kwezinto kunye nokuguguleka, nto leyo ephucula ukusebenza kakuhle koomatshini kunye nomgangatho womphezulu. Oku kuluncedo ngakumbi kwiinkqubo zokugaya ngokuchanekileyo kunye nokusika ngesantya esiphezulu.
4. Inobuhlobo nokusingqongileyo kwaye isebenza kakuhle kakhulu
Xa kuthelekiswa neendlela zokugquma zemveli, inkqubo ye-PVD ayifuni zininzi zeekhemikhali eziyingozi, nto leyo eyenza ukuba ibe yiteknoloji enobuhlobo nokusingqongileyo. Ukongeza, izixhobo zokugquma ze-PVD zisebenza kakuhle kakhulu, nto leyo evumela ukufakwa ngokukhawuleza ukuhlangabezana neemfuno zemveliso enkulu.
Inombolo 3: IiNdawo zokusetyenziswa zePVD Hard Coating
Oomatshini bePVD Hard Coating abasetyenziswa kakhulu kumashishini afuna ukusebenza okuphezulu komphezulu. Ezinye zeendawo eziphambili zokusetyenziswa ziquka:
1. Izixhobo zokusika kunye neeMbumba
Kwimveliso yezixhobo kunye nokungunda, ingakumbi kwizixhobo zokusika ezivezwe kumaqondo obushushu aphezulu kunye nokungqubana, iingubo zePVD ziphucula kakhulu ukumelana nokuguguleka, ukumelana nokugqwala, kunye nobunzima.
