摘要/Abstract

摘要： 由于金属材料增材制造技术的逐层成形过程特点，增材制造件存在着一些难以避免的问题，如表面粗糙、残余应力较高及由于粉末熔融不完全引起的亚表面微裂纹及气孔等，无法直接进行装配应用。综述结合了近年来国内外不锈钢增材制造件后处理工艺的研究成果及不锈钢增材制造件的缺陷类型，分析了不同增材制造工艺的区别及用途，以及目前国内外对增材制造件工艺参数的优化进展，热处理、机械加工等后处理工艺的国内外研究现状，总结了不锈钢增材制造件后处理工艺的关键问题，探讨了不锈钢增材制造件后处理工艺发展趋势。

关键词: 增材制造, 不锈钢材料, 后处理工艺, 可加工性, 残余应力

Abstract: The parts fabricated by Additive Manufacturing (AM) cannot be used directly due to the defects caused by layer-by-layer formation of AM, including coarse surface, high residual stress, and pores/micro cracks beneath the surface caused by insufficient melting. The review summarizes the research results of the post-treatment processes of stainless steel additive manufacturing components at home and abroad and the defect types of stainless steel additive manufacturing components, analyzes the differences and uses of different additive manufacturing processes, and current domestic and international optimization progress of the process parameters of the additive manufacturing components, heat treatment, mechanical processing and other post-treatment processes, The key problems of post-treatment process of stainless steel additive manufacturing pieces are summarized, and the development trend of post-treatment process of stainless steel additive manufacturing pieces is discussed.

Key words: additive manufacturing, stainless steel material, post-processing technology, machinability, residual stress
