ZINC PHOSPHATE COATING-MANGANESE PHOSPHATE COATING WITH DRY-TO-THE TOUCH OILING
ZINC PHOSPHATE COATING
MANGANESE PHOSPHATE COATING
Manganese phosphate coatings are mainly used to facilitate lubrication by reducing friction between reciprocal sliding surfaces. Being a sacrificial treatment, after a first phase of running-in, perfectly specular surfaces are obtained. Similarly, to zinc phosphate coating, also manganese phosphate coating can be impregnated with lubricating oils and waxes thus improving corrosion resistance.
The phosphate coating is velvety in appearance and varies in colour from dark grey and black; the weight of the deposited phosphate layer is included between 7 and 30 g/m2.
- Corrosion resistance
- Wear resistance of moving mechanical parts
- Facilitation of cold forming (drawing and extrusion)
- Excellent base for subsequent lubrication with oils and waxes
- Improved performance of further application of paint coatings and surface finishes
