THIS PRODUCT HAS BEEN TREATED WITH MANGANESE PHOSPHATING
Some items in our range undergo manganese phosphating, a metal surface treatment applied mainly to steel and some alloys.
The process consists of applying a layer of manganese phosphate onto the surface of the material to improve corrosion resistance and reduce wear.
How manganese phosphating works:
- Pre-treatment: the metal is thoroughly cleaned and prepared to remove oils, grease, oxides and any other contaminants from the surface;
- Treatment with phosphate solutions: the metal surface is immersed in an aqueous solution containing manganese salts, such as manganese phosphate (Mn3(PO4)2), which reacts with the metal to form a phosphate layer;
- Formation of the phosphate layer: the phosphate coating that is formed is microporous. This feature allows it to retain lubricants and oils, improving the anti-wear properties of the material;
- Rinsing and drying: the component is rinsed and dried at the end of the treatment to remove all solution residues.
Properties and advantages of the manganese phosphate layer:
- It has a microporous structure that retains lubricants and oils, ensuring optimal lubrication of metal surfaces.
- It promotes paint adhesion, making it ideal for components requiring subsequent protective treatments.
- Despite not forming an absolute barrier, manganese phosphate coating offers corrosion protection, especially in moderately aggressive environments, preventing oxidation and rust formation.
- It is wear-resistant. Its high durability makes it particularly suitable for components subjected to harsh working conditions, such as gears, motors and transmission components.
- It provides superior tribological properties, promoting lubrication and reducing friction between moving metal surfaces. This helps prevent wear and tear and prolongs the service life of components, even under high load and stress conditions.
- It ensures less friction between contact parts, improving smoothness and is perfect for gears and moving mechanisms.
- It reduces the need for maintenance because the layer retains its properties over time and increases the overall reliability of the component.
