Iingubo ze-PVD zibonisa ukumelana nobushushu obubalaseleyo, zizenza zilungele amacandelo aphantsi kobushushu obugqithisileyo kunye nokukhuhlana okuphezulu okanye ukubola kweekhemikhali. Umzekelo, iingubo zeTiAlN aziboneleli kuphela ngobulukhuni obukhethekileyo kodwa zikwagcina uzinzo kumaqondo obushushu aphakamileyo, zizenza zisetyenziswe ngokubanzi kwizixhobo zokusika kunye nokubumba ubushushu obuphezulu bezicelo zomatshini.
3. I-Coefficient ye-Friction ephantsi yoPhuculo oluPhuculweyo lokuSebenza
Iingubo ze-PVD zinceda ukufezekisa i-ultra-low friction coefficients, ukunciphisa ukukhuhlana kwezinto kunye nokunxiba, okwandisa ukusebenza kakuhle komatshini kunye nomgangatho ophezulu. Oku kunenzuzo ngakumbi kumatshini ochanekileyo kunye neenkqubo zokusika ngesantya esiphezulu.
4. Isebenzisana kakuhle nokusiNgqongileyo kwaye iSebenza ngokuPhezulu
Xa kuthelekiswa nobuchule bokwambathisa bemveli, inkqubo yePVD ayifuni imichiza emininzi eyingozi, nto leyo eyenza ukuba ibe bubugcisa obunobuhlobo nokusingqongileyo. Ukongeza, izixhobo zokugquma zePVD zisebenza ngokufanelekileyo, zenza ukuba ukubekwa ngokukhawuleza kuhlangabezane neemfuno ezinkulu zemveliso.
No.3 Iinkalo zeSicelo sePVD yoKugquma ngoNqanaba
Oomatshini bokugquma be-PVD abaqinileyo bezogquma basetyenziswa ngokubanzi kumashishini afuna ukusebenza okuphezulu komphezulu. Ezinye iindawo eziphambili zesicelo ziquka:
1. Izixhobo zokusika kunye neeMolds
Kwimveliso yesixhobo kunye nokungunda, ngakumbi izixhobo zokusika ezivezwe kumaqondo obushushu aphezulu kunye nokungqubana, iingubo zePVD zonyusa kakhulu ukuxhathisa ukunxiba, ukuxhathisa ukubola, kunye nokuqina.
