摘要
在阐述了复合增材制造技术的含义及关键技术特征的基础上,对基于机加工的复合增材制造、基于激光辅助的复合增材制造、基于喷丸的复合增材制造、基于轧制的复合增材制造四种复合增材制造技术的特点与优势进行了总结,并介绍了一种全新的激光锻造复合增材制造技术,其可与多种增材制造复合并能有效细化晶粒、消除缺陷和重构应力分布,最后指出了复合增材制造技术在耦合机理、参数优化及装备研制方面的发展趋势。
Based on expounding the technical meaning and key features of hybrid additive manufacturing (hybrid-AM),the features and advantages of hybrid-AM by machining,by laser processing,by shot-peering and by rolling are summarized and analyzed. Then,a new technology named hybrid-AM by laser forging is introduced,which can be coupled with other AM processes and effectively refine grains,eliminate defects and reconstruct stress distribution. Finally,the development trend of hybrid-AM technology in coupling mechanism,optimization of multi-processes parameters and equipment manufacturing is discussed.
