PVD txheej yog ib qho ntawm cov thev naus laus zis tseem ceeb rau kev npaj cov ntaub ntawv nyias nyias
Cov txheej zaj duab xis muab cov khoom nto nrog cov qauv hlau thiab xim nplua nuj, txhim kho kev hnav tsis kam thiab kev tiv thaiv corrosion, thiab ntev lub neej kev pabcuam.
Sputtering thiab vacuum evaporation yog ob txoj kev PVD txheej txheem tseem ceeb tshaj plaws.
1. Kev Txhais Lus
Kev tso pa tawm ntawm lub cev yog ib hom kev loj hlob ntawm cov pa tawm ntawm lub cev. Cov txheej txheem tso pa tawm yog ua tiav hauv lub tshuab nqus tsev lossis cov pa roj tsawg, uas yog, hauv cov ntshav kub qis.
Cov khoom siv los ua cov txheej yog cov khoom khov. Tom qab "ua pa los yog sputtering", ib txheej khoom khov tshiab uas txawv ntawm cov khoom siv hauv paus yog tsim rau ntawm qhov chaw ntawm qhov.
2, Cov txheej txheem yooj yim ntawm PVD txheej
1. Kev tso tawm cov khoom me me los ntawm cov khoom siv raw (los ntawm kev ua kom qhuav, sublimation, sputtering thiab decomposition);
2. Cov khoom me me raug thauj mus rau lub substrate (cov khoom me me sib tsoo nrog ib leeg, ua rau muaj ionization, recombination, reaction, energy exchange thiab movement direction change);
3. Cov khoom me me sib sau ua ke, ua nucleate, loj hlob thiab tsim zaj duab xis rau ntawm lub substrate.
