We offer manganese phosphate coating to shafts and hollow shafts up to 900 mm length with controlled thickness. The phosphate coatings need not stand for an extended length of time, because it is in the initial movements, that parts can be damaged and require lubricity eg. scoring of gears usually takes place in the first few revolutions, during this time, phosphate coating prevents intimate contact of the faces.
As the coating broken down in the operation, some of it is packed into pits or small cavities formed in the mating surfaces by the etching action of the acid during phosphating. Long after break-in, this material packed into the pits prevents direct contact of mating surfaces.
