Research Progress of Corrosion-resistant Titanium Alloys

Titanium and its alloys were widely employed in the field of Marine engineering because of their excellent corrosion resistance, however, because of the potential corrosion risks in the corrosive environment with high temperature, high-concentration acids and the presence of specific ions, the further application was limited in nuclear power, petrochemical and other fields. Therefore, the corrosion-resistant titanium alloys become an important direction in the field of titanium alloy research.The effects of the corrosion resistance of titanium alloys were introduced by several typical corrosion-resistant titanium alloys, including alloying elements, microstructure and corrosion environment. On this basis, the urgent problems and future research directions in the field of corrosion resistant titanium alloys were put forward
