Abstract

A resin coating is bonded to a metal base by treating a clean surface of the base with an oxidising agent, a metal powder and a resin, at least the treatment with the resin being effected at a temperature above the fusion temperature of the resin. The surface may be contacted with a composite coating comprising the oxidising agent, the metal powder and the resin, at least the oxidizing agent being in intimate contact with the surface, and the contacted surface is heated to a temperature above the fusion temperature of the resin. The surface may be treated with an oxidising agent; and is thereafter heated to above the fusion temperature of the resin and contacted with a mixture of resin powder and metal, or a dilute solution of the resin is applied to the surface and the surface is then heated to above the fusion temperature of the resin and whilst at this temperature, the metal powder is applied on the fused resin surface and the resin powder is applied thereon. The clean surface may be heated above the fusion temperature of the resin; at which temperature resin which has been treated with a solution of an oxidising agent and dried, is applied and metal powder is applied to the resin, or at which temperature metal powder which has been treated with a solution of an oxidising agent and dried, is applied and resin is applied to the metal powder. The oxidising agent may be chromic acid, molybdic and/or vanadic acid. The treated base may be allowed to cool, or may be heated to above the fusion temperature of the resin and resin is applied thereto, e.g. from a fluidized bed. The resin may be a chlorinated polyether or a fluorocarbon resin. The coating material may be applied as an aqueous or solvent dispersion of particles and fused into a coherent layer, by dipping the heated metal into a loosely settled bed of thermoplastic powder, by contacting the heated metal with a bed of powder in a state of aeration intermediate that of a fluidised bed and the loosely settled powder, or by spraying the heated metal with thermoplastic powder. The thermoplastic material may be nylon, chlorinated polyethers and fluorocarbon resins, e.g. polytrifluorochloroethylene. the metal may be aluminium, iron and steel, other metals and alloys. The metal surface may be cleaned by blasting or pickling. The metal powder may be of aluminium, silver, copper, nickel, iron, chromium, antimony, tin, molybdenum, or palladium.
