Kev Tsim Kho Ntawm PVD Technology
Mar 23, 2020| Kev tsim kho PVD thev naus laus zis
PVD thev naus laus zis tau tsim nyob rau xyoo 1970s. Cov yeeb yaj kiab npaj muaj qhov zoo ntawm siab hardness, tsis tshua muaj kev sib txhuam coefficient, zoo hnav tsis kam thiab tshuaj lom neeg ruaj khov. Thawj daim ntawv thov kev ua tiav zoo nyob rau hauv kev ua haujlwm ntawm kev kub ceev steel cuab tam tau nyiam cov xim ntawm kev tsim kev lag luam thoob plaws ntiaj teb. Piv nrog rau cov txheej txheem CVD, txheej txheem PVD muaj qhov kub tsis tshua muaj kev kub ntxhov thiab tsis muaj qhov cuam tshuam rau qhov khoov zog ntawm cov cuab yeej cov cuab yeej thaum ntsuas kub qis dua 600 ℃. Kev nyuaj siab sab hauv lub xeev ntawm zaj duab xis yog cov kev nyuaj siab, uas yog qhov tsim nyog dua rau txheej precision thiab complex carbide txiav cov cuab yeej. Cov txheej txheem PVD tsis muaj qhov tsis zoo rau kev tiv thaiv ib puag ncig, uas yog nyob rau hauv txoj kab nrog cov kev taw qhia txhim kho ntawm kev tsim khoom ntsuab niaj hnub. Tam sim no, PVD txheej tshuab tau dav siv hauv kev kho cov xim kho ntawm carbide kawg milling cutter, tho qhov, tho qhov, tho qhov, roj qhov xyaum, reamers, cov kais, indexable milling cutters, tshwj xeeb zoo li cutters, vuam cutters, thiab lwm yam.
PVD thev naus laus zis tsis tsuas txhim kho qhov sib zog ntawm cov zaj duab xis nrog cov cuab yeej matrix khoom siv, tab sis kuj txhim kho txheej txheej los ntawm thawj tiam ntawm TiN mus rau ntau txheej txheej txheej xws li TiC, TiCN, ZrN, CrN, MoS2, TiAlN, TiAlCN, tin -aln, CNX, DLC thiab ta-c.
