摘要：
A comparative assessment of the corrosion resistance of & alpha; and near-& alpha; (Ti-Al-Mo-V-Zr) titanium alloys produced by traditional technology (TT) and additive manufacturing (AM) was carried out. Electron beam melting was used for additive manufacturing of titanium alloys. The AM titanium alloys have poorer corrosion resistance in a 20 wt.% hydrochloric acid compared to TT ones. The relationship between corrosion resistance and the microstructure of titanium alloys manufactured by different technologies was established. Namely, corrosion resistance deterioration of AM & alpha;- and near-& alpha; titanium alloys is explained by the formation Widmannstatten and metastable martensitic structures.
