🔬 A Chemical Conversion Process
Unlike coatings that deposit an external layer (such as painting), phosphating is a conversion treatment. The steel surface reacts actively with a solution based on phosphate ions.
This reaction transforms the metal’s surface layer into a coating of microcrystalline metal phosphates, which are integrated directly into the material.
🛡️ Resistance and Versatility
Phosphating is widely used in the mechanical industry due to its distinctive properties:
- Corrosion Resistance: The phosphate layer acts as a stable chemical barrier that slows down the oxidation of the steel.
- Wear Resistance: The crystalline structure of the coating reduces friction and improves resistance to mechanical wear, making it ideal for components subject to rubbing.
- Lubricating Properties: Often, phosphating (especially manganese phosphating) is used to better retain lubricating oils on the surface of the parts.
🏗️ The Perfect Base for Other Treatments
Besides being an excellent final coating, phosphating is the “primer” par excellence:
Thanks to its controlled porosity and chemical nature, it guarantees exceptional adhesion for subsequent treatments, such as painting or the application of protective oils. This ensures that the final coating is much more resistant to peeling and underlying corrosion.
