Lub corrosion tsis kam ntawm niobium hlab piv rau titanium lossis stainless hlau?
Ntshiab nb seamless yeeb nkab
Niobium hlab muaj zoo dua corrosion tsis kam dua li titanium thiab stainless hlau, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig (piv txwv li hydrochloric acid, sulfuric acid).
Titanium yog muaj zog thiab lub teeb, thaum Niobium muaj peev xwm tsim oxide txheej, ua rau nws muaj ntau ruaj nyob hauv cov tshuaj xeb.
Stainless hlau, thaum kev lag luam, corrodes sai dua nyob rau hauv cov xwm txheej zoo sib xws. Niobium feem ntau siv nyob rau hauv kev tsim cov tshuaj uas muaj tshuaj lom neeg, cov khoom siv cua sov, thiab cov khoom siv hluav taws kub.
