近年来柴油机和汽油机的发展,要求进一步改进轴承材料。本文介绍新轴承材料的发展及其在试验台上的试验结果。 在高性能的铝基三层轴承中,用电镀的CuSn结合层代替常用的Ni栅层,改善了磨合性,提高了使用寿命。 在常用的CuPb三层轴承中。用同一种CuSn合金加在表面镀层与Ni栅层之间作为中间后,可以提高大功率发动机轴承的使用寿命。 上述发展项目已经发展到生产阶段。 本文介绍三个改进项目,它们的目的是改进在重负荷应用条件下,钢—铝和钢—铜—铅轴承(下作钢—A1和钢—CuPb)的性能。所有三个项目全部或多或少地发展到大量生产阶段。本文第一部分讨论新的CuSn层,用于A1和CuPb两种轴承。第二部分介绍物理蒸气喷镀的应用,它将A1Sn20喷镀到CuPb轴承上.
In recent years, the development of diesel engines and gasoline engines requires the further improvement of bearing materials. This article describes the development of new bearing materials and their test results on a test bench. In the high-performance aluminum-based three-layer bearings, the use of electroplating CuSn bonding layer instead of the common Ni grid layer to improve the run-in and improve service life. In commonly used CuPb three-bearing. With the same kind of CuSn alloy added between the surface coating and the Ni grid as the middle, you can increase the service life of high-power engine bearings. The development project has been developed to the production stage. This article describes three improvement projects whose purpose is to improve the performance of steel-aluminum and steel-copper-lead bearings (steel-A1 and steel-CuPb) under heavy-load application conditions. All three projects are all more or less developed to mass production. The first part of this article discusses the new CuSn layer for both A1 and CuPb bearings. The second section describes the use of physical vapor deposition, which will AlSn20 sprayed onto CuPb bearings.
