Abstract

Objectives: The Ti6Al4V ELI alloy produced via laser powder bed fusion (L-PBF) has attracted interest for use in dental applications. However, surface finishing is an important property that can be managed by various methods. The purpose of this study was to investigate the effects of electropolishing (EP) on the surface roughness and corrosion resistance of L-PBF Ti6Al4V ELI alloy.

Materials and methods: The present study explored the influence of current density (0.3 A/cm²), voltage (15 V), and distance (2 and 4 cm) on the surface quality of L-PBF-printed Ti6Al4V ELI. The potentiodynamic polarization testing was performed to investigate the corrosion behavior of electropolished Ti6Al4V ELI alloy plates.

Statistical analysis: The data variation was compared at different conditions of EP using a one-way analysis of variance and Tukey's post hoc testing at a significance level of 5%.

Results: This study showed that EP significantly reduced the surface roughness and enhanced corrosion resistance of printed Ti6Al4V ELI alloy with the best result achieved by using 15 V and 2 cm of anode-cathode distance.

Conclusion: This study indicates that customized EP settings are crucial for optimizing the surface properties of Ti6Al4V ELI for use in dental and biomedical applications. However, the corrosion resistance can be reduced due to increased porosity resulting from the EP treatment.

电抛光优化L-PBF Ti6Al4V ELI合金表面质量及其对牙用耐蚀性的影响

目的：采用激光粉末床熔合法制备Ti6Al4V ELI合金在牙科领域的应用备受关注。然而，表面处理是一个重要的特性，可以通过各种方法来管理。研究了电抛光（EP）对L-PBF Ti6Al4V ELI合金表面粗糙度和耐蚀性的影响。材料与方法：本研究探讨了电流密度（0.3 A/cm2）、电压（15 V）和距离（2 cm和4 cm）对l - pbf印刷Ti6Al4V ELI表面质量的影响。采用动电位极化试验研究了电抛光Ti6Al4V ELI合金板的腐蚀行为。统计分析：采用单向方差分析和Tukey事后检验，显著性水平为5%，比较不同EP条件下的数据差异。结果：本研究表明，EP可以显著降低Ti6Al4V ELI合金的表面粗糙度，增强其耐蚀性，其中在15 V和2 cm的阳极阴极距离下效果最好。结论：该研究表明，定制EP设置对于优化Ti6Al4V ELI的表面性能至关重要，可用于牙科和生物医学应用。然而，由于EP处理导致的孔隙率增加，耐腐蚀性可能会降低。
