摘要
作为一种固态沉积技术,冷喷涂增材制造(CS-AM)存在的主要问题是喷涂制备材料的塑性较差,而后续热处理可以有效改善这一问题,相关研究涉及冷喷涂Cu、Zn、Al、铝合金、Ti、Ti6Al4V、低碳不锈钢等金属涂层(材料)。本文概述了热处理对冷喷涂增材制造上述金属涂层(材料)电阻率、耐腐蚀性能以及力学性能的影响,为热处理在冷喷涂增材制造中的应用提供参考。
As a solid-state deposition technique,the main problem with cold spraying additive manufacturing(CSAM)is the poor ductility of sprayed depositions.Subsequent heat treatment can effectively solve this problem,related researches involved Cu,Zn,Al,aluminum alloy,Ti,Ti6Al4V and low carbon stainless steel coatings produced by cold spraying.This paper summarizes the effects of heat treatment on the electrical resistivity,corrosion resistance and mechanical properties of cold sprayed coatings,so as to provide guidance for application of heat treatment in cold spraying additive manufacturing.
