Manganese phosphating

steelprototypingISO 9001

The process of black Manganese Phosphating, resistant to corrosion, is applied on steel and cast iron surfaces It consists mainly of iron and manganese phosphate and reduces wear and tear on workpieces such as pistons, rings, cam shafts, engines, cams, and other similar surfaces. Layer weight may vary between 10 and 30 gr/m2 Among its properties we have the following: -It allows a quick braking of moving workpieces without wear, avoiding the contact of metal surfaces with metal. -It gives the workpiece a lower coefficient of friction, acting as an anti-seize finish. -Increases the lubrication of treated surfaces, since the coating absorbs oil. -It covers light scratches produced by the previous regrinding operations. -It slows the corrosion of the base metal. -The distribution and thickness of the coating is completely uniform throughout the workpiece since it is a chemical finish. Post Finishes The process of Manganese Phosphate may be finished with any of these finishes or combining several of them: -LUBRICANTS FOR FRICTION COEFFICENT (In any of its options) -DEHYDROGENATION -WATER-REPELLENT OILS -PATCH NYLON, MICROENCAPSULATION, ETC Resistance to Corrosion -From 05 to 48 Hours under Red Corrosion or base metal corrosion, according to phosphate layer and protection oil applied
