Surface treatment is the earliest by changing the mechanical, physical and chemical properties of the substrate material surface, so as to improve the product corrosion resistance, wear resistance and other performance of the surface protection technology, the traditional surface treatment methods mainly include: galvanized, electrophoresis, blue, black, passivation, phosphating, spraying, coloring, baking paint, immersion, shot blasting and so on. But at present, it has been widely developed in a variety of applications in metal, glass, plastic and other material component surface decoration or other special functional requirements of the surface processing technology, to achieve corrosion resistance, appearance, texture, function and other aspects of excellent performance.
The role of surface treatment:
Improve surface corrosion resistance and wear resistance, slow down, eliminate and repair material surface changes and damage;
To make ordinary materials have a special function of the surface;
Save energy, reduce costs and improve the environment.
Using modern physics, chemistry, metal science and heat treatment and other disciplines of technology to change the status and properties of the surface of the parts, so that it and the core material for optimal combination, in order to achieve the predetermined performance requirements of the process method, known as surface treatment process.
