Abstract

The laser controlled reactive synthesis method was developed to realize the synthesis and cladding of Ni3A1 intermetallic coating with expected thickness, width and low dilution on a steel substrate at a lower laser density of 3~3.5x 103W/cm2 by using the exothermic reaction. The clad is continuous and smooth, with few defects and excellent bonding with the steel substrate. Compared with the laser cladding of other alloys and ceramics without exothermic reaction, the cladding of intermetallic coating by laser controlled reactive synthesis can save a great amount of energy.
