【Abstract】 The characteristics of three kinds of head section bearing hardening processes, such as boronizing, carbide welding and laser phase change hardening are analyzed. A comparative study is carried out on the aspects of structural features, abrasion test and bearing test are made with the hardening processes denoted above. The test results show that the performance of head section bearing would be optimized with the process of laser phase change.更多还原
