DIN2391 St35 St37 St52 For Hydraulic Systems Black Phosphating Seamless High Precision Steel Tube
Phosphating is a surface treatment process in which a chemical reaction forms a film on the surface (phosphating film).
Phosphating process is mainly used on the metal surface, the purpose is also to provide a layer of protective film for the metal surface, so that the metal and air isolation, to prevent its corrosion; Can also be used for some products before painting the bottom, with this layer of phosphating film can improve the adhesion and corrosion resistance of the paint layer, improve the decorative so that the metal surface looks more beautiful, and can also play a role in the lubrication of some metal cold processing.
After phosphating treatment can make the workpiece in a long time will not oxidize rust, so phosphating treatment is widely used, is also a commonly used metal surface treatment process, in the automobile, shipbuilding, machinery manufacturing and other industries more and more applications.
1. Classification and application of phosphating
Usually, a surface treatment is presented with a color, but phosphating treatment can be based on actual needs, through the use of different phosphating agents will show different colors, which is that we often see phosphating treatment with gray, color or black.
Iron phosphating: after phosphating, the surface will show rainbow color and blue, so it is also known as color phosphorus, phosphating liquid mainly with molybdate as raw material, will form rainbow color phosphating film on the surface of iron and steel materials, also mainly used for coating the bottom layer, in order to achieve corrosion resistance of the workpiece and improve the binding force of the surface coating.
