Based on the foreign remanufacturing mode,which relies mainly on Part-Replacing Repair Method and Size-Changing Repair Method,China has explored and practiced the new remanufacturing mode,which relies mainly on Surface Repair and Performance Improving Method.The aim of remanufacturing forming is to renew rapidly the original size of the waste components rapidly,and then improve their service performance.The advanced surface engineering technology,especially the high density heat source surface forming technology,is the important technique to carry out rapid forming.Based on the arc heat source,plasma heat source and laser heat source,three kinds of high density heat source remanufacturing forming technologies,such as high speed arc spraying forming technology,micro-arc plasma forming technology,and laser cladding forming technology,have been developed.The benefits of remanufacturing forming based on advanced surface engineering technologies are great.
