| Abstract: | The effect of coating, which is formed with laser cladding and plasma spurt welding on base metal of anti acid stainless steel, on anti corrosion has be studied.A 5kW laser with CO 2 flow transverse is used for cladding Co base alloy or Ni base alloy powder replaced on the base metal. Comparing with the plasma spurt welding layers, the laser cladding layers have lower defect rate and dilution rate effected by base metal. And they have higher finished product rate, hardness and strength, fine microcrystal grain size, etc. The results of the test show that the laser cladding layers have superior properties of resistance to corrosion. |
