Titanium Qib 12 yog dab tsi?
Qib 12 titanium (Ti-0.3Mo-0.8Ni) muaj kev txhim kho corrosion ntau dua piv rau cov khoom lag luam uas muaj cov ntshiab titanium, thaum tuav tau zoo heev machinability thiab nruab nrab lub zog. Cov hlau no tau tsim los txuas cov kev sib txawv ntawm cov titanium ntshiab thiab kim dua corrosion-resistant alloys xws li Qib 7 titanium.
Los ntawm kev ntxiv molybdenum thiab npib tsib xee, Qib 12 titanium nthuav tawm cov kev tiv thaiv zoo tshaj plaws los txo cov kua qaub, crevice corrosion, thiab siab -kub chloride ib puag ncig, ua rau nws zoo tagnrho rau cov khoom siv tshuaj, cov khoom siv hluav taws xob, thiab cov khoom siv rau cov xov xwm corrosive uas cov ntshiab titanium qhov kev ua tau zoo twb dhau ntawm nws qhov txwv.
