Surface treatment is a process method to artificially form a surface layer on the surface of the substrate which has different mechanical,physical and chemical properties from the substrate. The purpose of surface treatment is to meet the corrosion resistance,wear resistance,decoration or other special functional requirements of the product.
For the metal castings,our common surface treatment methods are mechanical polishing,chemical treatment,surface heat treatment,spraying surface,surface treatment is to clean the surface of the workpiece,cleaning,deburring,deoiling, deoxidizing skin.
Principle of steel black oxide:
1. Blackening (bluing) oxidation film characteristics and application scope of steel chemical oxidation treatment also known as bluing.
The thickness of the film is about 0.5~1.5 microns, so it has no effect on the size of the workpiece. Since oxidation is carried out in an alkaline solution, no hydrogen embrittlement is generated in the oxidized workpiece.
The main composition of the oxide film is Fe3O4, called magnetic iron oxide. Compared with the oxidation film formed naturally in the air, the film layer is uniform and tight, but measured by the coverage standard, its protective performance is still very poor, need to dip soap liquid, dip oil or passivation treatment, protective performance and lubrication performance can be improved.
Oxidation is mainly used for precision parts of machinery, instruments, guns, etc., as well as protective and decorative workpieces that cannot be replaced by other cladding. Spring steel, thin steel wire, and steel sheet parts are also commonly used as protective oxide film.
