摘要

A comparative assessment of the corrosion resistance of conventionally manufactured (CM) wrought titanium and titanium produced by advanced technologies is studied. Powder metallurgy (PM), additive manufacturing (AM), and secondary manufacturing (SM) are chosen as the advanced titanium production methods. According to electrochemical tests, it is shown that titanium produced by advanced methods has worse corrosion resistance than wrought titanium (CM→AM→PM→SM). Its structural features (residual porosity, coarse grain, and elevated content of impurities) explain the lower corrosion resistance of titanium produced by the proposed methods.
