Kev kho tshuaj roughening
Coarsening kev kho mob yog coj cov tshuaj roughening tshuaj mus rau hauv lub boiling xeev, thiab kev txiav txim ntawm lub sij hawm yuav tsum tau nres thaum lub nto ntawm tus cab kuj yog tag nrho cov xim tooj liab. Cov txheej txheem no feem ntau cuam tshuam nrog molybdenum oxide thiab tooj liab oxide nyob rau saum npoo ntawm cov cab kuj. Tom qab cov tshuaj tiv thaiv oxide ua tiav, tooj liab yuav txo qis cov tshuaj tiv thaiv, tsim cov yeeb yaj kiab tooj liab uas npog lub substrate, zoo heev tiv thaiv kev tsim cov oxide zaj duab xis dua [2].
2.2.2 Tshuaj tua kab mob tshem tawm
Demembraning kev kho mob yuav tsum tau tshem tawm tag nrho cov tooj liab zaj duab xis nyob rau saum npoo ntawm cov cab kuj los ntawm cov tshuaj detachment tov nyob rau hauv chav tsev kub. Vim qhov tseeb tias cov yeeb yaj kiab tooj liab tsim thaum lub sijhawm coarsening tsuas yog npog lub substrate, yog tias tsis tshem tawm, nws yuav cuam tshuam rau cov txheej txheem tom ntej thiab yooj yim ua rau tsis xws luag xws li tev, foaming, thiab adhesion tsis zoo. Tom qab tshem tawm, qhov saum npoo yuav yog qhov ci molybdenum substrate. Lub sijhawm no, kev ua kom thiab npib tsib xee plating yuav tsum tau nqa tawm hauv lub sijhawm luv tshaj plaws los tiv thaiv cov khoom los ntawm oxidized dua.
2.2.3 Tom qab plating kev kho cua sov
Vim yog tsim cov qauv ntxeem tau thaum lub sij hawm tooj liab infiltration txoj kev rau kev ua molybdenum tooj liab cov ntaub ntawv, ua ke nrog tej yam mechanical ua, electroplating npib tsib xee tsis txaus los sau thiab npog lub qhov, thiab yuav tsum tau high-temperature tshav kub kev kho mob θ Kev kho cua sov ntawm 900 ~ 980 degree thiab t rau 20 ~ 30 feeb. Lub hom phiaj yog txhawm rau txheeb xyuas qhov ua tau zoo ntawm kev kho mob ua ntej, tshem tawm cov pa roj thiab lwm yam khoom los ntawm lub qhov hws, thiab ua cov txheej txheem thib ob ntawm cov khoom siv. Tom qab kev kho cua sov, cov cab kuj tuaj yeem plated nrog kub ntawm cov pa nickel nruab nrab txheej.
