PVD txheej tshuab rau cov rooj tog zaum

Rooj tog PVD txheej tshuab yog cov khoom siv tshwj xeeb siv los tso nyiaj siab rau saum npoo ntawm cov vaj huam sib luag lossis cov vaj huam sib luag. Nws siv cov pa hluav taws xob lub cev ua kom muaj tuab, zoo nkauj thiab ua haujlwm zaj duab xis nyob rau saum npoo ntawm substrate, ho txhim kho qhov zoo thiab muaj nuj nqis ntawm cov rooj tog khoom lag luam.

Cov Khoom Muaj Toj Zoo

Siab Hardness thiab Hnav Kuj: Cov txheej tsim (xws li tin, zrn, tic, thiab lwm yam) uas txhim kho qhov chaw thiab hnav tsis kam. Nws tsis yooj yim kom tau khawb thiab hnav tom qab ntev - tsis siv, thiab nws tseem zoo li tshiab.

Zoo heev corrosion

Cov txheej txheej ntom thiab kev siv tshuaj tsis ruaj khov thiab muaj kev tiv thaiv zoo heev - {{} ecidation muaj peev xwm.

Zoo bonding zog

Cov txheej sib khi tau ruaj khov rau lub substrate thiab tsis yooj yim rau tev tawm.

Nplua nuj ua kom zoo nkauj cuam tshuam

Ntau thiab cov xim ruaj khov: cov xim sib xyaw ua xim, muaj kev muaj zog ntau, muaj zog ntawm kev ntxhib los mos. Tsis muaj fading: Cov xim nkag mus tob rau hauv txheej thiab tsis yooj yim faded lossis tsaus ntuj los ntawm lub teeb, oxidation lossis hnav me me.

Kev Zoo Nkauj Lub Cev thiab Kev Ruaj Ntseg
Kev kub siab kuj: cov txheej tuaj yeem ruaj khov txawm tias muaj qhov kub siab dua thiab tsis yooj yim hloov xim.
Tshuaj Kuj: Nws muaj zoo tsis kam rau cov tshuaj ntxuav ib txwm, hws, qaug zog acids thiab tsis muaj zog alkalis, thiab lwm yam.

Siab -} kawg rooj tog hlau Cheebtsam

Xws li cov rooj zaum hlau, thav duab, cov txheej txheem hniav zoo nkauj tsis yog tsuas yog siv cov khoom siv sib xyaw ua ke ntawm cov khoom kim heev thiab tsim cov rooj tog zaum tag nrho thiab tsim ntawm cov rooj tog zaum tag nrho thiab tsim cov rooj tog zaum tag nrho thiab tsim cov rooj tog zaum.

Qhov no ua rau PVD txheej thev naus laus zis ntawm kev kho cov khoom hauv niaj hnub no, muab cov rooj tog zaum zoo los txhim kho cov khoom lag luam niaj hnub, ua kom muaj kev lag luam siab.
