摘要
研究了ＱＳｎ４－４－２．５锡青铜与４５＃钢的扩散连接，以及工艺参数对接头性能的影响，确定了锡青铜与钢扩散连接的最佳工艺参数：连接温度Ｔ＝８２０℃～８５０℃，连接压力Ｐ＝１．０ＭＰａ～２．０ＭＰａ，连接时间ｔ＝２０ｍｉｎ，接头抗拉强度可达１８０ＭＰａ以上，并运用金相、扫描电镜对接头进行了微观分析。
The diffusion bonding technology of Tin bronze QSn4-4-2.5 to steel was investigated in this paper. The influence of processing parameters on tensile strength of joints was studied, and a good quality joint of strength was up to 180 MPa was obtained with optimum bonding parameters of bonding temperature T =820℃～850℃, bonding pressure P =1.0 MPa～2.0 MPa, bonding time t=20 min.Microstructure of the joints was analyzed by metallurgical microscope and SEM.
