Abstract

The influence of an external magnetic field on the Ni–P–PTFE electroless composite coating process is investigated experimentally, and the mechanism of action of the field is discussed. The microstructure, hardness and friction coefficients of the composite coatings are determined, as is their elemental composition, and their corrosion resistance is tested. The results show that the external magnetic field accelerates the chemical plating reaction, leading to a dramatic increase in the rate of deposition of the coating. The presence of the magnetic field during plating leads to significant improvements in the quality of the coatings obtained in terms of increased particle content, better antifriction properties, greater corrosion resistance, greater density, lower porosity and better adhesion.
