| Abstract: | Laser cladding technique for rapidly repairing and surface strengthening metal stamping die was investigated. This tethnology is characterized hy using the method of laser cladding and special Ni-based tungsten earbide alloy powder to repair the damaged parts of the moht or to strengthen the surface of the unold. Furthermore, this technology is also applied to repair the hroken wheel hard with high pressure mold, to acquire metal ceramic layer without porosity and cracks,which can proolonz the service life of the high-hard pressture wheel mold |
