PURPOSE:To obtain a uniform plating film contg. silica, etc., and to increase the lightness when the surface of powder in an aq. suspension is brought into an electroless plating reaction, by adding silica sol, etc., to the suspension. CONSTITUTION:Powder of a base material to be plated is put in an aq. soln. to prepare an aq. suspension and the surface of the powder in the suspension is brought into an electroless plating reaction. At this time, silica sol and/or alumina sol is added to the suspension and a uniform plating film contg. silica and/or alumina is obtd. |
