Enhancement of Reliability of Machines and Materials by Friction Plating
A process of friction plating was developed for modification of the surface of metal items by strain hardening combined with application of protective coatings aimed to improve corrosion resistance, hardness, wear resistance and other functional properties. Friction plating is performed by means of a metal wire brush rotating at high speed. Coating material in the form of a rod or strip is pressed with a certain force to the rotary wire brush. In the contact zone, coating material is heated up to a high temperature. Particles of coating material are picked up by the ends of brush wires and transferred onto the treated surface. At the same time, the surface of the product is conditioned and heated. Investigations of friction plating have shown that plastic deformation of the surface layer combined with application of coating material particles ensures their strong adhesion to the substrate.
