Surface Treatment Chemicals: Phosphate Coating

Surface Treatment Chemicals – Phosphate Coating   Ferrous and non-ferrous metals undergo oxidation when combined with the oxygen in the air, resulting in corrosion. Thanks to surface treatments, corrosion is prevented and the metal is protected. Our company also produces chemicals serving such purposes. These chemicals, under the MET-Treat® brand, are developed in our R&D department to make them environmentally friendly and harmless. We ensure that the chemicals we produce are used in the most appropriate way by our customers with our expert technical staff in the field. In ferrous and steel materials, phosphating and black oxidation, and in aluminum and aluminum alloys, anodizing and chromium-free coating / chromate coating prevent the corrosion that would otherwise occur, creating a suitable environment for the next process to be applied. In this article, we will discuss phosphating and black oxidation in ferrous and steel materials.

Phosphate Coating

Phosphate coating of iron and steel is one of the most important surface treatment methods of today. Modern metal processing systems could not be carried out without phosphate coating processes being performed. Phosphating is widely used throughout the entire industry where metal is used. We can list the main areas where the phosphating process is used as follows: It is used in the protection of metals from corrosion together with paint and polymer film coatings, in cold forming processes such as wire drawing, pipe drawing, and deep drawing, in the protection of metals from corrosion together with protective oils and waxes, and in corrosion protection processes prior to final treatment applications.
