Precious Metal Cr yokhala ndi corrosion resistance

Chromium ufa ndi ufa wachitsulo womwe umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.Amapangidwa ndi kuchepetsa chromium oxide ndi aluminiyamu ufa mu ng'anjo yotentha kwambiri, zomwe zimapangitsa kuti pakhale ufa wabwino, wakuda wakuda ndi chiyero chapamwamba.

Chimodzi mwazinthu zodziwika bwino za ufa wa chromium ndi kukana kwake kwa dzimbiri.Amagwiritsidwa ntchito kwambiri popanga zitsulo zosapanga dzimbiri komanso ma alloys otentha kwambiri pazamlengalenga ndi mafakitale amagalimoto.Makhalidwe olimbana ndi dzimbiri a Chromium amathandizira kukulitsa kulimba komanso moyo wautali wa ma aloyiwa, kuwapangitsa kukhala abwino kugwiritsidwa ntchito m'malo ovuta.

Kupatula pa ntchito yake popanga zitsulo zachitsulo, ufa wa chromium umagwiritsidwanso ntchito ngati utoto popanga utoto, inki, ndi utoto.Kukula kwa tinthu ting'onoting'ono kwa ufa wa chromium kumapangitsa kukhala chisankho chabwino popanga zitsulo zapamwamba kwambiri.Zotsirizirazi zimapereka zokutira zokhazikika, zosagwirizana ndi dzimbiri zowala kwambiri, zomwe zimawapangitsa kukhala oyenera kugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza mafakitale amagalimoto ndi ndege.

Chromium ufa amagwiritsidwanso ntchito popanga zinthu zina, monga nickel-chromium alloys, zomwe zimagwiritsidwa ntchito kwambiri popanga zinthu zotentha.Ma alloys awa ndi abwino kuti agwiritsidwe ntchito pakutentha kwambiri, chifukwa cha malo osungunuka kwambiri komanso kukana dzimbiri.

Mwachidule, ufa wa chromium ndi chinthu chosunthika chokhala ndi zinthu zabwino kwambiri zokana dzimbiri.Amagwiritsidwa ntchito kwambiri popanga zitsulo zosapanga dzimbiri, ma alloys otentha kwambiri, komanso zitsulo zomaliza.Makhalidwe ake amapanga chisankho choyenera kuti chigwiritsidwe ntchito m'malo ovuta komanso kutentha kwambiri, ndikupangitsa kuti ikhale yotchuka m'mafakitale osiyanasiyana.
