摘要
轴承零件(套圈及滚子)在激光微精处理后所产生的影响因轴承材料的不同而异。普通轴承钢GCr15在激光微精处理后虽能产生有利于润滑的微凸体,但在微凸体与基体之间存在一弱化过渡区;而Cr4Mo4V在微精处理后既能产生高硬度的微凸体,又不存在弱化的回火过渡区。因此,该材料在微精处理后既有较高的高温疲劳强度,又有较好的润滑性能,这为提高航空发动机主轴承使用寿命提供了有益的途径。附图6幅,参考文献4篇。
Bearing elements, that is, rings and rollers, neve different influence according to different materials after laser micro precision treatment . Although common bearing steel GCrl5 after laser micro precision treatment can form transverse ronghness which is of benefit to Inbrication, yet a weakenedre-gion can also be formed between transverse roughness and s bstrate . M50 after laser micro precision treatment can not only form highly hard transverse roughness, but also doesn't form a weakened tempering region. Thus, this material after laser micro precision treatment has both higher temperature fatique strength and better lubrication property. This provides a useful way for improving the service life of rolling bearings in aircraft engines.
