Cov lus Askiv luv luv rau lub cev vapor deposition, lossis PVD, yog lub cev vapor deposition. Nws suav nrog kev siv lub tshuab nqus tsev ruaj khov, tsis tshua muaj hluav taws xob, lub tshuab hluav taws xob siab tam sim no, cov pa tawm mus rau vaporize thiab ionize cov khoom siv, thiab acceleration ntawm hluav taws xob teb kom tso cov khoom vaporized thiab nws cov tshuaj tiv thaiv cov khoom ntawm lub workpiece.
Xyoo 1970s pom qhov kev taw qhia ntawm PVD thev naus laus zis, thiab cov yeeb yaj kiab tsim tau txais txiaj ntsig los ntawm cov yam ntxwv zoo li lub zog hardness, tsis tshua muaj kev sib txhuam coefficient, zoo hnav tsis kam, tshuaj lom neeg ruaj khov, thiab lwm yam.Global industrial industries tau mloog zoo rau kev siv thawj zaug hauv kev lag luam. high-speed steel tej cuab yeej. Lawv tau ua haujlwm zoo dua ntawm cov txheej txheem rau cov khoom siv ceramic thiab cemented carbide thaum tsim cov khoom siv txheej txheej. Tshawb nrhiav kev siv txheej txheej.
PVD txheej txheem as opposed to CVD processThe internal stress state of the film is compressive stress, which is more suited for coating carbide precision and complex tools. Cov txheej txheem PVD tsis muaj qhov tsis zoo rau ib puag ncig thiab yog nyob rau hauv txoj kab nrog kev txhim kho ntawm kev tsim ntsuab niaj hnub. Kev ua haujlwm kub yog qhov tsawg, thiab lawv tsis muaj kev cuam tshuam rau kev khoov lub zog ntawm cov khoom siv thaum kub qis dua 600 degree .Tam sim no, txheej txheej txheej rau cemented carbide kawg mills, xyaum, kauj ruam xyaum, roj qhov xyaum, reamers, kais, indexable milling inserts, cov cuab yeej tshwj xeeb zoo li, vuam cov cuab yeej, thiab lwm yam yog nquag siv PVD txheej tshuab. Nrog PVD thev naus laus zis, cov txheej txheem txheej tau hloov ntawm TiN mus rau TiC, TiCN, ZrN, CrN, MoS2, TiAlN, TiAlCN, TiN- AlN, CNx, DLC, thiab ta-C txheej, ntxiv rau ntxiv dag zog rau kev sib txuas ntawm cov yeeb yaj kiab thiab cov khoom siv matrix.
