【Abstract】 The microstructure characteristics of three kinds of rein-forced layers respectively produced by laser remelting,alloying and cladding are de-scribed by comparing the processes of the above three methods. The thickness, hardness and wear properties of laser treated layers are analyzed. It is pointed out that laser cladding is one of the most prospectively applicable method for improving wear properties of aluminium alloys.更多还原
