Based on the analysis of the typical construction machinery parts failure mode, the properties of the arc spray coating and the application background were introduced. The application status of high velocity arc spraying developed in anticorrosion oil equipment, pump plungers, boiler equipment and automobile engine and several other construction machinery parts fields were overviewed. Furthermore, the prospect of the high velocity arc spraying technology using remanufacturing in construction machinery parts was also analyzed in detail . It may be have the important guidance in remanufacturing developed in repair of construction machinery parts.
