Surface Treatment

By using some physical, chemical, mechanical, or composite methods to make the metal surface have a different organizational structure, chemical composition, and physical state from the matrix, thereby enabling the treated surface to have different properties from the matrix.

A method used to improve the surface condition and mechanical, physical, or chemical properties of a workpiece. Generally, products manufactured by mechanical processing methods such as casting require further cleaning, hardening, grinding, polishing, painting, or electroplating on all or part of their surfaces to enhance their various characteristics, smoothness, and aesthetics.

Effect:

1. Increase the mechanical properties such as surface hardness, wear resistance, and fatigue resistance, and apply them to molds, pistons, cylinders, tool machines, slides, shafts, gears, etc.

2. Improve surface roughness and friction, apply to sliding surfaces of mechanical components, shafts and bearings, cutting tools, tools, etc.

3. Change the surface's reflection of light, selective absorption, weather resistance and other characteristics, and apply them to mirrors, automotive and locomotive parts, etc.
