不只堆叠，更要融合--激光粉末床打印 CoCrMo–Ti6Al4V 复合材料的工艺优化

From Layering to Bonding: A Process Strategy for CoCrMo–Ti6Al4V Composite Fabrication Using Selective Laser Melting

摘要

本研究聚焦钴铬钼合金（CoCrMo）与钛合金（Ti6Al4V）的跨材料体系复合制备难题，系统开展了基于选择性激光熔融（SLM）技术的复合制造工艺研究。通过优化激光功率这一关键工艺参数，并结合外部支撑件辅助，实现异质材料的界面冶金结合。微观表征表明，CoCrMo 疏松层的引入可有效缓解异质材料间的热应力失配，使界面结合强度显著提升。研究证实，基于参数–结构双维度调控策略，可稳定制备具有稳定异质界面的 CoCrMo–Ti6Al4V 复合材料。
