Titanium muaj zog corrosion kuj nyob rau hauv alkali thiab alkaline xov xwm. Ob qho tib si sodium hydroxide, potassium hydroxide, ammonia, calcium hydroxide, thiab magnesium hydroxide yog cov tshuaj tiv thaiv corrosion heev. Tus nqi corrosion ntawm titanium hauv boiling saturated calcium hydroxide, magnesium hydroxide, thiab ammonia dej yog yuav luag 0. Nyob rau hauv qhov kub thiab txias thiab siab concentration sodium hydroxide tov, xws li 50 feem pua ~ 73 feem pua kuaj ntawm 188 degree, tus nqi corrosion yuav ntau tshaj 1 09mm/a. Txawm li cas los xij, hydrogen embrittlement rhiab heev ntawm titanium nyob rau hauv high-temperature alkaline kua yuav tsis raug ignored. Thaum qhov kub siab tshaj 77 degree thiab pH tus nqi ntawm cov tshuaj alkali ntau dua 12, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov muaj peev xwm ntawm hydrogen nqus thiab hydrogen embrittlement ntawm titanium hauv cov tshuaj alkali.
