Powdery alloy processing material in site by movable laser smelt-coating process

A movable field processing alloy powder material for the laser melting is to reinforce the nickel-base alloy using the below elements: Cr, W, Mo, Al, Ti, Co; also it can be added with the Co, C, N, Nb, Cu, B, Si and the minim rare-earth metal which can be the Ce, Y and the Hf. The invention has the high hardness, the strength and the low melting point, high wearing resistance. It has improved the cracking resistance, moldability, the stability and the uniformity of the laser melting layer. So it can repair the high temperature alloy, the carbon steel, the structural steel and the stainless steel by the laser melting.
