Abstract

In this study, the selective laser melting Ti6Al4V alloy was modified for the first time by hot stamping post-treatment. The hot stamping treatment improved corrosion resistance, almost 2.38 times the selective laser melting sample. The improved corrosion resistance was attributed to the reduction of porosity with 67.7 % (0.62 % → 0.20 %) and average grain size with 29.9 % (3.65 μm → 2.56 μm) while the increase of β phase fraction with 368.8 % (0.16 % → 0.75 %) and low angle grain boudary fraction with 57.4 % (15.34 % → 24.15 %). Hence, this study concluded that the hot stamping treatment was a feasible method to enhance the corrosion resistance of selective laser melting Ti6Al4V alloy.

采用热冲压后处理提高选择性激光熔化Ti6Al4V合金的耐蚀性

本研究首次采用热冲压后处理方法对选择性激光熔化Ti6Al4V合金进行了改性。热冲压处理提高了耐蚀性，几乎是选择性激光熔化样品的2.38倍。孔隙率降低了67.7%(0.62%→0.20%)，平均晶粒尺寸降低了29.9% (3.65 μm→2.56 μm)， β相分数提高了368.8%(0.16%→0.75%)，低角晶界分数提高了57.4%（15.34%→24.15%）。因此，本研究认为热冲压处理是提高选择性激光熔化Ti6Al4V合金耐腐蚀性能的可行方法。
