本成果研究了45#钢与锡青铜的扩散连接,确定了钢与锡青铜扩散连接的最佳工艺参数(连接温度820℃～850℃,连接压力1.0ＭＰａ～2.0ＭＰａ,连接时间20ｍｉｎ),接头抗拉强度可达180ＭＰａ以上。运用金相扫描电镜对接头进行了微观分析。本成果研究的某航空发动机中精密摩擦副要求使?
The results discussed the diffusion bonding between 45 # steel and tin bronze, and determined the best technological parameters of diffusion bonding between steel and tin bronze (connection temperature 820 ℃ ~ 850 ℃, connection pressure 1.0MPa ~ 2.0MPa, connection time 20min) Tensile strength up to 180MPa or more. The microstructure of the joint was analyzed by metallographic scanning electron microscope. The results of the study of aero-engine precision friction requirements make?
