Improvement of wear resistance of parts by the combined method
With the aim of improving the coating quality, productivity and economy of solid lubricant, the solid lubricating coating was applied with a binder based on phenol-formaldehyde resin. The coating was applied combined method using ultrasonic hardening treatment, which allows to obtain on the surface of a regular microrelief, covered with a thin film formed by the friction modifiers. Deformation of the coating with ultrasound has led to a significant improvement of the quality of the coating, increasing the adhesion strength of the coating to the substrate, reduces the porosity of the surface layers, reduced surface roughness, the orientation of the solid lubricant in the layer parallel to the plane of sliding"extra" coverage.
