Spray powder in the thermal spray material occupies a very important position. Thermal spraying alloy powder including nickel-based, iron-based and cobalt-based alloy powder, according to different coating hardness, respectively, used in mechanical parts repair and protection. Thermal spraying technology after years of development in the country has formed a complete equipment research and production system, currently engaged in the work of more than 20 units, capable of producing all types of oxyacetylene flame spraying equipment, spray melting Equipment, arc spraying equipment, complete sets of plasma spraying equipment, spray welding equipment, all kinds of special equipment and so on.
