Qhov sib txawv ntawm titanium phaj thiab stainless hlau

Yog hais tias nws yog cov ntshiab titanium phaj, nws tsuas yog muaj cov tshuaj titanium. Titanium yog lub teeb heev. Feem ntau siv nyob rau hauv kev lag luam aerospace, tshuaj thiab kuj yog corrosion resistant, yog li no tus nqi siab dua.
Stainless hlau yog pheej yig dua. Lawv kuj tau siv ntau dua. Yog vim li cas vim li cas stainless hlau tsis yooj yim rau xeb yog cuam tshuam nrog cov ntsiab lus chromium hauv cov hlau ntau tshaj 12.5%. Chromium can quickly form a dense passivation film on the steel surface in oxidizing corrosion and non-corrosive media to prevent the metal matrix from being damaged. Thaum cov ntsiab lus chromium siab dua 12.5%, qhov ntom ntom thiab ruaj khov passivation zaj duab xis yog tsim. Lub peev xwm los tiv thaiv xeb hloov pauv sai thiab muaj peev xwm tiv thaiv xeb tau zoo heev. Qhov no yog vim li cas cov ntsiab lus chromium hauv stainless hlau yuav tsum tshaj 12%.
Muaj 304 cov khoom siv tshuaj 1Cr18Ni9Ti feem ntau siv hauv cov ntaub ntawv stainless hlau, ib qho zoo li xa mus rau cov ntsiab lus carbon. Cr18 hais txog cov ntsiab lus chromium. Ni9 hais txog cov ntsiab lus ntawm NiTi, uas yog, titanium hauv titanium phaj.
