PVD txheej txheej txheej txheem thiab txheej txheem thev naus laus zis cuam tshuam

PVD txheej txheej txheej txheem thiab txheej txheem thev naus laus zis cuam tshuam

PVD yog lub npe luv ntawm lub cev nqus dej (Lub cev Vapor Deposition) ua lus Askiv. Nws hais txog kev siv hluav taws xob qis, high-current arc tawm tshuab hauv qab lub tshuab nqus tsev, thiab kev siv cov pa tawm los uaLub hom phiajEvaporate thiab ionize vaporized substance thiab gas, thiab siv qhov nrawm ntawm lub tshuab hluav taws xob kom tso cov tshuaj vaporized thiab nws cov tshuaj tiv thaiv ntawm cov khoom ua haujlwm.

 

PVD thev naus laus zis tau tshwm sim nyob rau xyoo 1970s, thiab cov yeeb yaj kiab npaj tau muaj qhov zoo ntawm kev ua kom siab, qis txhuam coefficient, zoo hnav tsis kam thiab tshuaj lom neeg ruaj khov, thiab lwm yam. Thawj qhov ua tiav daim ntawv thov hauv thaj tsam ntawm cov cuab yeej siv hlau txiav ceev tau nyiam mloog zoo los ntawm kev tsim khoom lag luam thoob ntiaj teb. Thaum txhim kho kev ua tau zoo thiab muaj kev ntseeg siab txheej txheej txheej, lawv kuj tau ua tiav cov txheej txheej tob tob hauv cov cemented carbide thiab cov cuab yeej txiav tej hub. Txheej Kev Tshawb Fawb.

 

 

Sib piv nrog txheej txheem CVD,Txheej txheem PVDKev ua haujlwm kub tsawg, thiab nws tsis muaj qhov cuam tshuam rau qhov khoov lub zog ntawm cov cuab yeej cov khoom thaum qhov ntsuas kub qis dua 600 ℃; lub xeev kev nyuab siab sab hauv ntawm zaj duab xis yog kev nyuab siab, uas yog qhov tsim nyog rau txheej txheej ntawm carbide qhov tseeb thiab cov cuab yeej nyuaj; txheej txheem PVD tsis muaj kev cuam tshuam tsis zoo rau ib puag ncig, thiab ua raws li Txoj Cai Kev Txhim Kho ntawm kev tsim ntsuab tshiab tam sim no, PVD txheej thev naus laus zis tau siv dav hauv txheej txheej txheej ntawm cov cemented carbide kawg mills, kev xyaum, kauj ruam xyaum, roj qhov xyaum, reamers, cov kais dej, indexable milling inserts, tshwj xeeb-puab cov cuab yeej, vuam cov cuab yeej, lwm yam..

 

PVD thev naus laus zis tsis tsuas yog txhim kho kev sib zog ua kom muaj zog ntawm cov yeeb yaj kiab thiab cov cuab yeej matrix khoom, tab sis txheej txheej kuj tseem tsim los ntawm TiN mus rau TiC, TiCN, ZrN, CrN, MoS2, TiAlN, TiAlCN, TiN-AlN, CNx, DLC, thiab ta-C. txheej.
