The surface treatment method can remove the unstable foreign matters on the metal surface, such as unstable burr, white layer and isolated alloy composition, smooth the surface defects such as micro cracks and small holes, and smooth the irregular surface with sharp edges to form a metal surface suitable for coating.
In the processing step, the powder with predetermined particle size and abrasive properties is mixed with compressed air, and then blown to the target metal surface at a predetermined pressure to remove unstable burrs, white layers or separated substances on the surface.
A good surface treatment has a predetermined particle size and abrasive performance. The two powders are mixed with compressed air, and then blown to the metal surface under a predetermined pressure, so that the sharp corners of the metal surface become round and flat, and the small holes flatten.
The powder is mixed with compressed air, and then blown to the target metal surface under a predetermined pressure to form fine irregularity. The size of fine concave convex is preferably 1-5 μ. The metal material is a metal material with any metal surface treatment method.
