Deoxidation thiab pickling ntawm titanium alloys

Kev kho deg feem ntau yuav tsum tau thaum lub sij hawm thiab tom qab kev kho cua sov kom tshem tawm cov hlau nto oxide nplai thiab ntau yam kuab paug, txo cov kev ua ntawm cov hlau liab qab, thiab tseem ua ntej thiab thaum lub sij hawm siv cov txheej tiv thaiv thiab ntau yam txheej txheem ntawm titanium thiab nws cov alloys. Kev siv cov txheej txheem no txhim kho kev ua haujlwm ntawm cov hlau nto, xws li tiv thaiv corrosion, oxidation, thiab hnav.
Cov txheej txheem pickling ntawm titanium thiab nws cov alloys nyob ntawm seb hom (cov yam ntxwv) ntawm oxide txheej thiab cov txheej txheem cov tshuaj tiv thaiv uas twb muaj lawm, uas tau cuam tshuam los ntawm cov txheej txheem kub kub thiab qhov nce hauv kev ua haujlwm kub (xws li forging, casting, vuam, thiab lwm yam. .). Ntawm qhov kub ua haujlwm qis lossis kub cua kub hauv qab li ntawm 600X, tsuas yog ib txheej oxide nyias xwb. Thaum qhov kub thiab txias, thaj chaw muaj pa nplua nuj diffusion yog tsim nyob ze ntawm ib txheej oxide, uas yuav tsum tau muab tshem tawm los ntawm kev ntxuav cov kua qaub. Muaj ntau txoj hauv kev los tshem tawm oxide nplai tuaj yeem siv tau: cov cuab yeej siv rau kev tshem tawm cov tuab oxide txheej thiab cov txheej txheej tawv tawv, cov txheej txheem tshem tawm oxide nplai hauv cov ntsev da dej, thiab cov txheej txheem tshem tawm oxide nplai los ntawm cov kua qaub ntxuav hauv cov kua qaub.
Feem ntau, kev sib xyaw ua ke ntawm ntau txoj hauv kev tuaj yeem siv tau, xws li kev tshem tawm oxide nplai thiab tom qab pickling, Xwb, kev sib xyaw ntawm ntsev da dej thiab tom qab ntxuav kua qaub yuav siv tau los tshem tawm oxide nplai. Nyob rau hauv cov ntaub ntawv ntawm oxide thiab diffusion txheej tsim nyob rau hauv ntau dua kub, tshwj xeeb txoj kev yuav tsum tau siv. Txawm li cas los xij, thaum rhuab mus rau 600X ntawm qhov kub thiab txias, feem ntau ntawm cov oxide txheej tsim tuaj yeem yaj los ntawm kev ntxuav cov kua qaub.
