Abstract

Aiming to the problem of surface roughness caused by the adhesion of powder on the surface of TC4Ti-alloy fabricated by Selective Laser Melting (SLM), the influence of chemical etching process, including the formula of etching solution and process parameters, on the surface roughness of the SLMed Ti-alloy was investigated. The results shown that the ratio of HF/HNO₃ of the etching solution and the etching time are the main influencing factors. Among them, HF play an important role in reducing the surface roughness of the fabricated Ti-alloy. However, this reducing effect of HF will be weakened as the ratio of HF/HNO₃ decreases. For a constant ratio of HF/HNO₃ (say HF/HNO₃=1/4), the surface roughness decreases obviously with the increasing etching time, but when the etching time is too long, it will cause damage to the substrate. After etching in the solution of HF∶HNO₃=1∶4 for 9 minutes, the surface roughness of the fabricated TC4 Ti-alloy is 2.52 μm. At the same time, the etching process has little effect on the size of the sample (with c.a.0.12 mm of thickness reduction), in other words, the etching process reached an optimal state at this time.

Key words: metallic materials selective laser melting TC4 titanium alloy chemical corrosion surface roughness
