ABSTRACT:
Metal-polymer composite articles, e.g., knobs, nuts, trimmings or ornaments, automotive components including grilles, headlamp bezels and surrounds, wheel covers, trim, hubs and like parts, having silvery hued metal surfaces comprise surface plating composed essentially of an alloy of tin and Group VIII metal that is durably joined to a supportive solid body containing a directly electroplateable polymeric material, e.g., a composition wherein carbon black and sulfur are combined with a polymer. Polyvinyls, polyolefins, polystyrenes, elastomers, polyamides and polyesters are among the suitable polymers. A durably adherent layer of nickel-based metal is disposed between the body and the surface plating. Durability of the surface plating includes resistance to thermal cycling and to salt spray corrosion. Disclosure includes process whereby article is prepared with electroplating of nickel-based and tin-based metal strata to provide desirable composite articles expeditiously at low cost for high quality production.
