摘要
Abstract
Four major types of remanufacturing techniques,namely,brush plating,thermal spraying,TIG welding and laser deposition,are compared in terms of their characteristics and suitability for remanufacture of high-speed train unit axles.And the advantages of laser remanufacturing technique as a new-type manufacturing technology are summarized.It is clear that laser deposition is overall superior to the other three.Further discussion is provided regarding the equipment and key technology of laser deposition,the characteristic of microstructure of laser deposition layer,and the development of metal powder materials.More importantly,ultrasonic impact treatment is introduced to relieve the residual stress.It is indicated that laser deposition with proper powder materials and surface posttreatment should be able to meet the remanufacturing requirement of high-speed train unit axles.关键词
