Bearing metal surface treatment

Metal material surface treatment techniques with metal heat treatment and surface heat treatment are not a type of concept. Generally, the metal surface protection and modification is called the metal material surface treatment, and changing the metal material surface organization structure and mechanical properties index is called the metal surface heat treatment.

Contents of surface protection: electroplating, coating, chemical treatment layer; electroplating includes (galvanizing, copper, chromium, lead, tin, tin, cadmium, cadmium, etc.); coating includes (paint coating, electrostatic powder spraying process); chemical treatment includes (blackening treatment, phosphorization treatment). On the other hand is the surface modification of metal, also known as surface optimization, is with the aid of ion beam, laser, plasma new method, change the surface and interpretation of the surface of the material of segmentation, structure and quality, with the traditional gold and surface outsourcing technology of new thin layer material, or make the traditional material can have better parts. The modern surface modification technology mainly includes physical vapor deposition (PD), chemical vapor deposition (CVD), plasma chemical vapor deposition (PCVD), ion injection and ion beam deposition.

Metal surface treatment process

There are mechanical polishing, chemical polishing, phosphorization coating, spray spray, electroplating electrophoresis, oxidation blackening, coloring, anodic oxidation.

Surface treatment process of metal steel

The range of surface treatments is wide. Some are to increase the surface hardness, some for anticorrosion, some for beauty. In general, there is surface heat treatment, such as chloride quenching, carburization process, and blue; polishing; spraying; plating; and also used for cold hardening.
