Titanium plating yog txheej txheej txheej ntawm titanium hlau los ntawm electrochemical method
Tso lus
"Titanium plating" yog txheej txheej ntawm titanium hlau zaj duab xis los ntawm cov txheej txheem electrochemical.
Titanium plating yog nyob rau hauv kub kub, nqus titanium kub rauv, titanium, zirconium hlau. Cov hlau los yog alloy vapor yog ionized los ntawm lub ci tawm ntawm cov roj inert, thiab cov ions tau nrawm los ntawm cov hluav taws xob hluav taws xob thiab sib sau ua ke ntawm cov phaj tsis zoo stainless hlau, yog li tsim cov yeeb yaj kiab hlau nplua nuj thiab zoo nkauj. Qhov no tseem hu ua PVD txheej, uas yog lub cev vapor deposition. Stainless hlau txheej, tseem hu ua stainless hlau titanium / zirconium txheej, yog nyob rau hauv lub thawv nqus tsev vacuum, ib tug ionic zaj duab xis txheej ntawm titanium / zirconium compound yog tsim nyob rau saum npoo ntawm stainless hlau, thiab zaj duab xis txheej yuav tsis ploj mus ntau xyoo nyob rau hauv ib tug sab nraum zoov ib puag ncig. Daim ntawv thov ntawm PVD txheej thev naus laus zis feem ntau muab faib ua ob pawg: cov txheej txheem zoo nkauj thiab cov cuab yeej txheej. Lub hom phiaj ntawm cov hniav plating yog tsuas yog los txhim kho cov tsos, zoo nkauj muaj nuj nqi thiab xim ntawm lub workpiece, thiab ua rau lub workpiece ntau hnav-resistant thiab corrosion-resistant mus cuag nws cov kev pab cuam lub neej; Qhov no feem ntau yog siv nyob rau hauv ntau yam kev lag luam kho vajtse, xws li lub qhov rooj thiab qhov rais hardware, locks, chav dej kho vajtse thiab lwm yam lag luam.
Argon ua cov pa ua haujlwm rau lub tshuab nqus tsev plating
1. Thaum plating cov yeeb yaj kiab hlau, argon feem ntau yog siv los ua cov roj ua haujlwm. Nws yog ib qho roj inert thiab yuav tsis tsim oxidation thaum lub substrate yog rhuab nyob rau hauv lub nqus tsev vacuum. Feem ntau hais lus, argon yog siv los kho lub siab ntawm lub cub tawg, thiab cov nyhuv ntawm cov xim tsis pom tseeb!
2. Cov pa oxygen feem ntau yog siv los npog cov yeeb yaj kiab uas tsis yog xim hlau, xws li TiO2, yog li tsis tas yuav txhawj xeeb txog cov yeeb yaj kiab oxidation tom qab txheej.
3. Nitrogen yog cov roj uas rushed mus rau hauv lub tshuab nqus tsev chamber thaum lub hom phiaj yog hloov thiab coated, thiaj li hais tias lub siab nyob rau hauv lub nqus tsev vacuum chamber thiab atmospheric siab yuav tsum sib npaug zos, kom lub hau yuav qhib thiab lub hom phiaj yuav coated. nrog rau lwm txheej ntawm zaj duab xis.
