本工作旨在综合评价不同表面改性对Ti6Al4V合金选区激光熔凝(SLM)、铸造和锻造表面粗糙度的影响。对Ti6Al4V表面进行了Al_2O_3(70~100µm)和ZrO_2(50~130µm)喷丸处理，用0.017摩尔/dm~3氢氟酸对120 S进行了酸蚀处理，并进行了喷丸和酸蚀的组合处理。结果表明，SLM法制备的Ti6Al4V零件表面粗糙度的优化与铸造法和锻造法有很大的不同。实验结果表明，激光烧结和Al_2O_3喷丸-HF腐蚀制备的Ti6Al4V合金表面粗糙度较高(Ra=2.043µm，Rz=11.742µm)，而铸态和锻造的Ti6Al4V合金表面粗糙度分别为(Ra=1.466，Rz=9.428 m)和(Ra=0.940，Rz=7.963 m)。Ti6Al4V锻造件表面粗糙度Ra=1.631µm，Rz=10.953µm，高于SLM Ti6Al4V件(Ra=1.336µm，Rz=10.353µm)和铸造Ti6Al4V件(Ra=1.075µm，Rz=8.904µm)。
This work aimed to comprehensively evaluate the influence of different surface modifications on the surface roughness of Ti6Al4V alloys produced by selective laser melting (SLM), casting and wrought. The Ti6Al4V surface was treated using blasting with Al2O3 (70–100 µm) and ZrO2 (50–130 µm) particles, acid etching with 0.017 mol/dm3 hydrofluoric acids (HF) for 120 s, and a combination of blasting and acid etching (SLA). It was found that the optimization of the surface roughness of Ti6Al4V parts produced by SLM differs significantly from those produced by casting or wrought processes. Experimental results showed that Ti6Al4V alloys produced by SLM and blasting with Al2O3 followed by HF etching had a higher surface roughness (Ra = 2.043 µm, Rz = 11.742 µm), whereas cast and wrought Ti6Al4V components had surface roughness values of (Ra = 1.466, Rz = 9.428 m) and (Ra = 0.940, Rz = 7.963 m), respectively. For Ti6Al4V parts blasted with ZrO2 and then etched by HF, the wrought Ti6Al4V parts exhibited higher surface roughness (Ra = 1.631 µm, Rz = 10.953 µm) than the SLM Ti6Al4V parts (Ra = 1.336 µm, Rz = 10.353 µm) and the cast Ti6Al4V parts (Ra = 1.075 µm, Rz = 8.904 µm).
