Description:

Metal powder spray gun (metal powder spray torch) oxyacetylene flame self-fluxing alloy powder spray torch is a high temperature generated by the combustion of oxyacetylene flame, and the workpiece which has been subjected to surface degreasing and rust cleaning in advance, using oxyacetylene The flame is heated to 300-400oC, and then the spray tip is sprayed from the surface of the workpiece to 120-150mm. The self-fluxing alloy powder is evenly sprayed on the surface of the workpiece through the oxyacetylene flame, and then flame-melted to the surface after specular reflection. The molten position is moved so that the alloy powder and the workpiece base material are mutually dissolved, mutually diffused, and mutually infiltrated to form a dense and firm metallurgical bonding layer. If a variety of different alloy powders are used, the reinforced surface layer can be achieved with different properties such as abrasion resistance, corrosion resistance, high temperature resistance and impact resistance.
