Abstract Electrochemical measurements in 1 M HCl solution were performed to investigate the corrosion behaviour of Ti–6Al–4V alloy fabricated by electron beam melting (EBM) with cylindrical axes deviating from the building direction by 0°, 45°, 55°, and 90°. Microstructure characterization before and after the tests was carried out by using a variety of methods The results suggested that the corrosion resistance of EBM alloy in 1 M HCl solution increased slightly in the order of 45°, 90°, 55°, and 0°. Such difference can be ascribed to the grain boundary density and β phase constitution, which varied with the building direction.

电子束熔炼Ti-6Al-4V合金耐腐蚀性能的构造方向依赖性

摘要 在 1 M HCl 溶液中进行电化学测量以研究通过电子束熔化 (EBM) 制造的 Ti-6Al-4V 合金的腐蚀行为，其圆柱轴偏离构建方向 0°、45°、55°和 90 °。使用多种方法对试验前后的显微组织进行表征 结果表明，EBM 合金在 1 M HCl 溶液中的耐腐蚀性能在 45°、90°、55°和 0° 的顺序中略有增加。这种差异可以归因于晶界密度和β相组成，它们随构建方向而变化。
