FAILURE ANALYSIS OF HYDROGEN CORROSION OF CHEMICAL EQUIPMENTS MADE OF TITANIUM ALLO
钛制换热器氢腐蚀破坏失效分析

Failure analysis of two chemical equipments made of titanium alloy were conducted by means of macroscopic and microscopic analysis,chemical composition analysis as well as microstructure analysis.The results showed that both of the two chemical equipments made of titanium failed because of hydrogen corrosion.The titanium absorbed hydrogen and led to formation of large amount of TiH2,which then caused the corrosion failures such as brittle breaking and flaking off on the surface of titanium equipments.
