Phosphatization, which is mainly used as a pretreatment in paint and lubrication applications, is one of the most important surface treatments today.
It is widely used to protect metals from corrosion and to facilitate cold forming processes.
It is very important that the surface is free of grease, rust and other dirt before plating to ensure proper adhesion of the phosphate plating to the surface.
In the industry, it can be applied in three ways as iron phosphate, zinc phosphate and manganese phosphate.

Iron Phosphate:It is the oldest phosphatization method. Although its application, installation and operation costs and controls are easy, the corrosion resistance is low compared to other types.
For this reason, it is preferred for plating products that will work in closed environments which are not exposed to much corrosion.

Zinc Phosphate: It is a phosphating type which is widely used in automotive and supply industry, electronic tool industry which require long term corrosion resistance.
Although it is suitable for bad weather conditions, it is resistant to lower pressure and temperature than manganese phosphate plating.

Manganese Phosphate:It is the hardest, best corrosion and highest wear resistance plating type among all phosphate platings.
Due to its ability to absorb and retain oil for a long time, its use is common for gear, motor, piston etc. moving parts.
