摘要
为提高选区激光熔化(SLM)医用Ti6Al4V钛合金的成形质量, 优化了激光分区扫描工艺参数。通过正交实验和单因素实验, 对比分析了分区扫描策略和传统整体扫描策略下成形零件的显微组织结构特征、致密度、尺寸精度和表面质量, 总结了SLM成形医用Ti6Al4V钛合金的典型表面形貌。研究结果表明, 分区扫描策略不仅能获得尺寸精度高和表面质量良好的钛合金成形件, 而且能显著改善悬垂面的成形效果。
Abstract
In order to improve the forming quality of medical Ti6Al4V titanium alloys by selective laser melting (SLM), the process parameters of laser partition scanning are optimized. By the orthogonal experiment and single factor experiment, the microstructure characteristic, efficiency of space filling, dimensional accuracy and surface quality of formed parts under the partition scanning strategy and the traditional overall scanning strategy are compared and analyzed. The typical surface morphologies of medical Ti6Al4V titanium alloys formed by SLM are summarized. The research results show that the partition scanning strategy can not only increase the dimensional accuracy and surface quality of titanium alloys, but also significantly improve the forming effect of overhanging surfaces.
