ANALYZE AND RESEARCH OF CORROSION RESISTANCE OF LASER CLADDING LAYER ON THE ANTI-ACID STAINLESS STEEL SURFACE

摘要

The effect of coating, which is formed with laser cladding and plasma spray welding on the base metal of anti-acid stainless steel, on anti-corrosion has been analyzed and 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 spray welding layers, the laser cladding layers have lower defect rate and higher product rate. The result of test shows that the laser cladding layers have higher corrosion resistance properties.
