Mo合金化纯Ti电化学行为研究
The investigation of Mo alloying on the electrochemical behaviour of pure Ti
摘要
Abstract
The effect of pure Ti alloyed with different Mo 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 volume fraction of β phase increased,the grain size of α phase decreased,and the corrosion resistance was improved with the increase of Mo content.The warburg impedance appeared in the low frequency region of impedance spectroscopy obtained at open circuit potential(OCP).When the Mo content was below 1.0%,there were many corrosion pits on the surface after electrochemical corro-sionthe.Passivation film formed by polarizing at 1.0 V vs Ref for 4 hours exhibited n-type semiconduct-or behavior,and the conductivity increasesd with Mo content greater than 1.0%.关键词
