Corrosion of titanium materials by sodium sulfite solution
Thread Content
What is the corrosion effect of sodium sulfite solution on titanium materials? What if it is in acidic or alkaline conditions, with the presence of impurities such as sulfate ions and sodium chloride? (Temperature less than 120 degrees). I appreciate your advice!
Chloride ions find it difficult to disrupt the passivation of titanium; therefore, titanium has good corrosion resistance to chloride ions. However, it is highly susceptible to corrosion in reducing acids such as hydrochloric acid and sulfuric acid. Titanium exhibits good corrosion resistance to most alkaline solutions (even those containing free chlorine), but suffers severe corrosion in alkaline solutions containing ammonia. Moreover, in the boiling alkaline solution of PH12, titanium absorbs hydrogen, which may lead to hydrogen embrittlement
