Titaniyamu ndi okosijeni zimapanga filimu yamphamvu komanso wandiweyani yomwe ili pamwamba pawo. Muzinthu zambiri zowononga zowonongeka, filimu ya oxide iyi imakhala yokhazikika komanso yovuta kusungunuka. Ngakhale itawonongeka, malinga ngati pali mpweya wokwanira, imatha kudzikonza yokha ndikuyambiranso mwamsanga.

Chitsulo cha titaniyamu cha mavavu a titaniyamu chimakhala ndi kukhazikika kwabwino komanso kuthekera kodziyendetsa pakathiridwa okosijeni kukhala mafilimu oonda m'malo owononga kwambiri. Makhalidwe ake amatha kukana dzimbiri mwamphamvu pansi pazikhalidwe zosiyanasiyana zogwirira ntchito. Ma valve a titaniyamu amadalira kukhazikika kwa mankhwala a filimu ya passive oxide pamwamba pawo muzofalitsa zowononga kuti zisawonongeke m'malo ogwirira ntchito. Kwa kusalowerera ndale, oxidizing, ndi kuchepetsa mofooka malo ochezera, filimu ya passive oxide yokha imakhala yokhazikika. Kuchepetsa zowononga media ndi kutentha kwambiri kapena otsika pH mfundo, kuti apititse patsogolo bata la kungokhala chete okusayidi filimu awo, dzimbiri zoletsa monga mpweya, madzi, heavy metal ayoni, ndi anions akhoza kuwonjezeredwa, ndi pamwamba ion kusinthidwa ndi anodizing mankhwala angathe. kugwiritsidwa ntchito kukonza kukana kwa dzimbiri ndi kuuma kwapamtunda kwa titaniyamu pochepetsa media.
