摘　　要：介绍了激光再制造技术的原理、方法及其在球墨铸铁曲轴修复中的具体应用,通过对再制造发动机曲轴的具体方法研究,找出适合球墨铸铁曲轴修复的再制造工艺,并且研究了曲轴修复后涂层的组织和性能、摩擦磨损性能,结果表明,通过适当的再制造方法对曲轴进行修复,可以得到满意的制造表层组织和性能,有效延长曲轴的使用寿命。This paper introduces the principles and methods of the technology of laser remanufacturing. And specific application in the restoration of nodular cast iron crankshaft.by studying the specific method of the restored workpiece for laser manufacturing, the technology of laser manufacturing for restored crankshaft of modular cast iron have been found. The organization, properties and frictional wear of laser remanufacturing coating for restored crankshaft of nodular cast iron are also studied. The result shows that the restoring crankshaft of nodular cast iron by using the method of laser remanufacturing can get satisfactory and organization, and the performance and the service life of crankshaft are effectively prolonged.
