Thaum cov ntsiab lus hydrogen hauv titanium tubing ntau dhau lawm, qhov cuam tshuam toughness thiab lub zog tensile yuav txo qis vim yog brittleness, yog li cov ntsiab lus hydrogen hauv titanium tubing feem ntau tau teev tseg kom tsis pub ntau tshaj {{0}} .015%. Txhawm rau txo qhov nqus ntawm hydrogen, cov khoom hauv kev kho cua sov yuav tsum tau muab tshem tawm ua ntej cov ntiv tes, dov zeb cov cim, roj thiab lwm yam khoom seem, tsis muaj dej vapor nyob rau hauv qhov chaw ntawm lub qhov cub kho cua sov. Yog hais tias cov ntsiab lus hydrogen ntawm lub titanium raj tshaj qhov tso cai, nws yuav tsum tau muab tshem tawm los ntawm lub tshuab nqus tsev annealing. Dehydrogenation ntawm lub tshuab nqus tsev annealing feem ntau yog nyob rau hauv 538-760 degree , tsawg dua 0.066 Pa siab los tuav 2-4 teev.
Thaum qhov kub tsis tshaj 540 ° C, oxide zaj duab xis nyob rau saum npoo ntawm lub titanium raj yuav tsis thickened, thiab nyob rau hauv lub kub kub kho kub (760 ° C los yog ntau tshaj), tus nqi oxidation yuav ceev ceev, Tib lub sijhawm, cov pa oxygen mus rau sab hauv nthuav dav ntawm cov khoom siv los tsim cov txheej txheem diffusion - cov pa phem txheej. Oxygen contamination txheej muaj ib tug siab nkig piv uas ua rau tawg thiab puas rau ntawm qhov chaw.
Tshem tawm cov pa paug txheej txheej muaj cov txheej txheem kev ua haujlwm (xws li sandblasting, chav chipping, thiab lwm yam), los yog pickling, tshuaj milling thiab lwm yam kev siv tshuaj, hauv kev kho cua sov, lub sij hawm cua sov yuav tsum luv luv kom ntau li ntau tau raws li qhov chaw ntawm kom ntseeg tau tias kev kho cua sov meteoric nce, tab sis kuj nyob rau hauv lub tshuab nqus tsev vacuum los yog inert gases (argon, nitrogen, thiab lwm yam) nyob rau hauv lub cua sov rauv. Daim ntawv thov tsim nyog kuj tseem tuaj yeem zam lossis txo cov pa phem uas tsim los ntawm titanium raj qhov chaw rhuab hauv cua sov.
