| Abstract: |
| Axle is an important part of transmission supporting parts, which transfers movement and power. Its main failure mode is wear. In order to choose a proper repairing method for axles with worn-out failure and implement under corresponding repairing technology condition, to ensure the repairing quality and improve the repairing efficiency, comparative study was conducted on three kinds of surface technology methods including electric arc spraying, electric brush plating and electric spark deposition from the aspects of theory and practical application. The results showed that all three methods could repair the worn-out axle under proper technology parameters. When the wear status of axle was well distributed wear and the wearing capacity was within a certain range (usually limited to 2 mm), electric arc spraying with mechanic combination was chosen to repair the failure axle. When the wear status of axle was well distributed wear and the wearing capacity was small (usually limited to 0. 5 mm), electric brush plating with mechanic combination and Waals forces combination was chosen to repair the failure axle. When the wear status of axle was groove or other forms, electric spark deposition with metallurgy combination was chosen to repair the failed axle. |
