摘要： The present invention is applicable to composite particles for composite dispersion plating used for forming a self-lubricating composite dispersion coating and a method of plating using such composite particles as well as a plating (coating) using the same. The purpose of the invention is to obtain a composite particle for composite dispersion plating which is comprised of a particle with an excellent capability of reducing the friction and a low or very low specific gravity, and a method of plating using such composite particles. In this invention, each of the composite particles includes a friction-reducing mother or core particle (1) encapsulated with shell particles (2) comprised of the same components as a base metal of a composite dispersion plating bath (5). This provides a composite particle for composite dispersion plating which is comprised of a particle with an excellent capability of reducing the friction and a low or very low specific gravity. As a result, the composite particles can form an eutectic system in a plating layer without addition of any surfactant.
