Kev kho deg feem ntau yuav tsum tau ua thaum thiab tom qab kev kho cua sov kom tshem tawm cov nplais oxide thiab ntau yam kab mob ntawm cov hlau nto, txo cov kev ua haujlwm ntawm cov hlau liab qab, thiab siv cov txheej tiv thaiv thiab ntau yam txheej txheej ntawm titanium thiab nws cov alloys. Kev kho deg yuav tsum tau ua ua ntej thiab thaum lub sij hawm txheej txheej txheej. Cov txheej no yog siv los txhim kho cov khoom ntawm cov hlau nto, xws li tiv thaiv corrosion, oxidation thiab hnav.
Cov txheej txheem pickling ntawm titanium thiab nws cov alloys yog txiav txim siab los ntawm hom (cov yam ntxwv) ntawm oxide txheej thiab cov txheej txheem tshuaj tiv thaiv uas twb muaj lawm, thiab hom txheej txheej no cuam tshuam los ntawm cov txheej txheem cua kub kub thiab qhov nce hauv kev ua haujlwm kub (piv txwv li. forging, casting, vuam, thiab lwm yam).
Tsuas yog ib txheej oxide nyias yog tsim los ntawm kev ua haujlwm qis dua lossis kub kub ntawm 600X lossis qis dua. Nyob rau hauv qhov kub thiab txias, ib qho chaw uas muaj oxygen-nplua nuj diffusion yog tsim nyob ze ntawm ib co oxide txheej, uas yuav tsum tau eluted los ntawm acid. Ntxiv nrog rau cov txheej txheem oxygen-nplua nuj diffusion no. Muaj ntau txoj kev descaling tuaj yeem siv tau: kev siv tshuab los tshem tawm cov txheej txheem oxide tuab thiab cov txheej txheej tawv tawv, descaling hauv molten ntsev da dej thiab pickling hauv cov kua qaub kom tshem tawm cov nplai.
