摘　　要：SS316L alloy coupled with Inconel625 alloy were combined with Ti6Al4V or Inconel718 alloy through wire arc additive manufacturing technique to manufacture functionally graded materials(FGMs).Two FGMs,namely 60%SS316L+20%Inconel625+20%Ti6Al4V composite and 60%SS316L+20%Inconel625+20%Inconel718 composite,were prepared.The tensile strength,elongation,yield strength,hardness,cross section area of the parent material,and composition were analysed.Results illustrate that the 60%SS316L+20%Inconel625+20%Inconel718 composite has better mechanical properties than 60%SS316L+20%Inconel625+20%Ti6Al4V composite,and the comprehensive properties of 60%SS316L+20%Inconel 625+20%Ti6Al4V composite are better than those of the parent material SS316L.Hence,the composite of 60%SS316L+20%Inconel625+20%Inconel718 is optimal.Due to its high strength,the 60%SS316L+20%Inconel625+20%Inconel718 composite has great application potential in the field of high pressure pneumatic tool and defence tool.通过电弧增材制造技术,将 SS316L合金和Inconel625合金与Ti6Al4V或Inconel718合金结合,制备功能梯度材料(FGMs)。制备了2种FGMs,分别为60% SS316L+20% Inconel625+20% Ti6Al4V复合材料和60% SS316L+20% Inconel625+20% Inconel718复合材料。对抗拉伸强度、伸长率、屈服强度、硬度、母材的横截面积和成分进行了分析。结果表明,与 60% SS316L+20% Inconel625+20%Ti6Al4V 复合材料相比,60% SS316L+20% Inconel625+20% Inconel718 复合材料具有更好的力学性能;同时,60% SS316L+20%Inconel625+20% Ti6Al4V复合材料的综合性能优于母材SS316L。因此,60% SS316L+20% Inconel625+20% Inconel718复合材料是最佳选择。由于其高强度,60% SS316L+20% Inconel625+20% Inconel718复合材料在高压气动工具和防御工具中具有巨大的应用潜力。
