Abstract
The process of electro-depositing a smooth level coating of metal, e.g. chromium on to a base metal containing surface depressions comprises filling in the surface depressions with a viscous electrically conductive plastic containing a conductive powder mixture consisting of 10-90% flaky particles and 90-10% fibrous particles, the particles comprising Fe, N, Co or Fe3O4 or Cu2O, hardening said plastic, removing excess plastic thereby forming a level surface and electro-depositing a smooth level metal coating on said surface. The plastic may comprise a polyester resin, for instance prepared by the reaction of glycerine and fumaric acid, the reaction product being cross-linked by further reaction with styrene. A polymerization catalyst such as a solution of methyl ethyl ketone peroxide in dimethyl phthalate may be used. Before treatment the base metal may be vapour degreased with trichloroethylene, cleaned by blasting with grit, and heated to about 95 DEG C. for 4 hours to liberate any gases occluded therein.ALSO:An electrically conductive composition comprises a resin vehicle and a conductive powder consisting of 10-90% flaky particles and 90-10% fibrous particles, said particles consisting of iron, iron alloy, cobalt, nickel, magnetite or cuprous oxide. The resin vehicle may be a saturated or unsaturated polyester resin. Saturated polyester resins used may be formed by reaction of phthalic anhydride, isophthalic acid, hexahydrophthalic anhydride or tetrachlorophthalic anhydride with ethylene glycol, propylene glycol, butylene glycol, diethylene glycol or dipropylene glycol. Unsaturated polyesters used may be formed using fumaric or citrionic acids, e.g. with glycerine, or maleic acid. The resins may be set by heating, by use of an oxidizing agent, e.g. methyl ethyl ketone peroxide, or by cross linking with a vinyl monomer, e.g. styrene diallyl phthalate, vinyl toluene, triallyl cyanurate, methyl vinyl ketone, acrylonitrile or an acrylic ester such as methyl methacrylate.
