A METHOD FOR MANUFACTURING A SOLID PLATING MATERIAL AND THE SOLID PLATING MATERIAL MANUFACTURED BY THE METHOD

摘要

A process for producing a solid-plated material having a coating layer excellent in conductivity and durability. A coating fluid containing an organic binder is mixed with conductive particles for plating and metal particles for binding to prepare a suspension. The suspension is sprayed on core particles which are being centrifugally fluidized to thereby form on th e surface of the core particles a coating layer comprising the plating particl es and the binding metal particles tenaciously bonded with the organic binder. Thereafter, the core particles are heated to a temperature not lower than th e melting point of the binding metal particles to thereby remove the organic binder by pyrolysis and simultaneously melt the binding metal particles. Thu s, a fusion-bonded layer containing the plating particles tenaciously bonded ca n be formed on the surface of the core particles. When particles of a material having excellent conductivity are used as the particles for plating, a solid - plated material having a coating layer excellent in conductivity and durability can be produced.
