The acidic phosphating
One of the most frequent ways for achieving phosphate coatings on metals is through acidic phosphating. This method uses acidic solutions containing phosphate compounds that form a thin and uniform coating of phosphate on the surface. Phosphate coating not only promotes corrosion resistance, but it also enhances the adhesion of following coatings like paint or powder.
Advantages
- Increased corrosion resistance
- Improved adherence
- Minimizing friction
