| Abstract: | Optimization of process variables for laser cladding or Ni based alloy coating and30%(vol) TiCp, WCP and SiCp, respectively reinforcing Ni based alloy composite coatingswas performed using replaced powder method. The effect of laser cladding process can be assessed based on the dilution and clad appearance of the coatings. There exists an optimalpower density range for each kind of coating associated with the balance of the forgiving ofthe cladding process and the refinement of the final microstructure of the clad. |
