Abstract
Ceramics particles of Al2O3 and SiC (mean diameter:'40-770μm) were coated with fine metal particles of Al, Ni, Co, Mo and W (mean diameter: 5-10μm) by the agglomeration coating technique in which ceramics particles containing polyethylene glycol as binder were mixed with metal particles in a rotating cylinder and heated above the melting point of polyethylene glycol so that metal particles were fixed on the surface of ceramics particles by the molten binder. The quantity of metal coating reached a maximum of about 60 vol%. Coarser ceramics particles attained a larger quantity of metal coating. The addition of Al-stearate to metal particles was effective to disperse metal particles and increase the surface coverage of the coating.
