With the increase of revolution and load in modern automobile, the behavior requirement for material becomes higher and higher. In order to improve further the mechanic and technologic properties, the preparation process and technique of steel-copper double metal axle bush material made by powder metallurgy method was investigated. The main composition of copper alloy powder was QCuPb24Sn1. The experiments show that the quality of products is affected by physic properties of QCuPb24Sn1 powder, sintering parameter, rolling parameter, the quality of steel backing and its treating. The measure results show that metallurgical bonding is gained between steel backing and copper alloy with the interfacial bond strength reaching 200~300MPa, which improves the thermal fatigue resistance strength. The interfacial diffusion of alloying element is an important factor to microstructure, apparent hardness and interfacial bond strength.

随着现代汽车发动机转速及负荷的增加,对轴承轴瓦材料的性能要求也愈来愈高。为进一步改善铜铅合金轴瓦材料的机械、工艺性能,试验研究了以QCuPb24Sn1为主要成份的粉末冶金钢铜合金双金属翻边轴瓦材料的制备过程与工艺技术。试验表明,QCuPb24Sn1合金粉末的物理化学性能、烧结工艺参数、轧制工艺参数、钢背材质及其处理是影响材料性能的主要因素。并用法向拉伸强度检测、弯头强度检测、硬度试验、金相性能检测等方法检测了制品的有关性能。结果表明,粉末冶金法制得的铜铅合金与钢背间形成了牢固的冶金结合,界面法向结合强度可达到200~300MPa,显著提高了材料的抗疲劳强度;元素在界面两侧的扩散是影响材料显微组织、表观硬度及界面结合强度的关键。
