摘　　要：以MoSi2/316L梯度材料作为过渡层,采用放电等离子烧结技术实现了MoSi2与316L不锈钢的连接,着重研究了烧结温度、烧结压力及保温时间对MoSi2/316L接头组织形貌的影响。结果表明:烧结温度与压力的升高有利于改善接头组织与形貌,保温时间对连接性能影响不大;在50MPa、1050℃×10min工艺条件下,可得到致密的MoSi2/316L连接接头,该接头无宏观缺陷及层间开裂,界面结合紧密,组织形貌良好。Joining MoSi2 to 316L stainless steel was investigated using the spark plasma sintering （SPS） technique. The influence of sintering temperature, sintering pressure, and holding time on morphology of MoSi2/316L joints was studied as well. It demonstrates that increase of the sintering temperature and pressure can improve the joints morphology. Holding time has marginal effect on joint properties. The dense MoSi2/316L, joint produced at pressure of 50MPa, temperature of 1 050℃ for 10min has no any macrodefect.
