Abstract
A process for coating an electrically nonconductive material with a metal by attaching a less noble metal or a compound thereof, in pulverous form, to the surface of the electrically nonconductive material and spraying a solution of the nobler metal on the surface thus coated in order to cause the nobler metal to adhere to the surface.
Claims7
A process for coating an electrically nonconductive material with a metal, comprising impregnating the surface of the nonconductive material with a metal or compound thereof in pulverous form less noble than the metal used for coating the surface of the nonconductive material, by first applying a coarser powder of said less noble metal or compound having a particle size of approximately 50-500 .mu.m and then, on the surface, applying a finer powder of said less noble metal or compound having a particle size of 1-50 .mu.m, and finally spraying a solution of the nobler metal on the surface of the electrically nonconductive material.
