摘要
Abstract
The effect of pure Ti alloyed with different Ru content on the microstructure and electro-chemical behaviour was studied for the need of further improvement in corrosion resistance and con-ductivity of titanium bipolar plates in proton exchange membrane water electrolysis environments.Res-ults indicated that the α-Ti equiaxed grains were refined,the corrosion resistance was improved with the increase of Ru content.The Warburg impedance appeared in the low frequency region of impedance spectroscopy obtained at OCP.When the Ru content is below 0.08％,the passivation film formed by po-larizing at 0.8 V vs Ref for 6 h exhibits p-type semiconductor behavior,and the conductivity remains constant.关键词
