Heavy Weight Manganese Phosphating Solution for Iron and Steel

INTRODUCTION

Manganese phosphating is a process used to produce crystalline, oil absorptive coating with excellent wear resistance. These coatings are applied to facilitate initial break in of new parts such as piston rings, crankshaft, cylinder liners, differential gears and transmission gears. The etch pattern produced by manganese phosphate on the surface of parts greatly improves oil retention and prevents galling of contact surfaces. In addition to their anti-friction characteristics, manganese phosphate coatings exhibit excellent corrosion resistant properties when used with suitable post rinse and rust preventative oil.
