镍-金刚石复合镀层修复磨损电动机主轴工艺

A Process to Repair the Worn Main Shaft for 380kW Motor by Composite Ni-diamond Coating

通过对380kW电动机磨损主轴失效原因的分析,提出了修复该零件的新工艺。采用镀覆特殊镍—Ni-金刚石复合镀层体系,提高了镀层与基体,镀层与工作层的结合力,增加了修复层的硬度,改善了主轴配合面的耐磨性,使修理质量得到了提高。

A new repairing technology was proposed based on the failure analysis of worn main shaft of 380kW motor. The adhesion between the coating and coating, coating and basis material was increased by using the special Ni-Composite Ni-diamond coating system, and the hardness of the repairing coating was increased. So that the wear resistance of the repaired surface of main shaft and the repairing quality were improved.
