    Abstract: In a mechanical plating process, oxidation-prone metals, such as aluminum, titanium, magnesium, and mixtures thereof, can be applied to metal substrates without the corrosion problems encountered in the prior art. To avoid such problems, the substrate is plated with the oxidation-prone metal and relatively minor amounts of an immersion metal and, optionally, a protective metal. The immersion metal which can be salts or oxides of metals selected from the group consisting of tin, copper, nickel, cadmium, zinc, lead, and mixtures thereof coats the oxidation-prone metal in forming a mechanical plating coating and prevents formation of an oxide layer on the oxidation-prone metal. The protective metal which may be selected from the group consisting of zinc, cadmium, and mixtures thereof prevents oxidation of the plated metal substrate when exposed to the environment. An etching agent is used either prior to and/or during mechanical plating.

    Abstract: A method is disclosed for treating the surface of a polymeric plastic substrate in a chemical plating process incorporating a preliminary chromic acid etch followed by one-step activation in a tin-palladium hydrosol. The method involves the step of immersing the substrate in a dilute aqueous acid solution of stannous chloride between the etching and activating steps.

    Abstract: A METHOD OF AND COMPOSITION FOR PROMOTING ADHESION BETWEEN PLATED METAL AND A PLASTIC SUBSTRATE, IN WHICH THE ACTIVE AGENT IS PROVIDED IN FINELY DIVIDED DISPERSED OR COLLOIDAL AQUEOUS EMULSION FORM. THE ACTIVE AGENTS ARE ANY OF A GROUP OF LOW MOLECULAR WEIGHT ORGANIC UNSATURATED COMPOUNDS OF THE FATTY ACID TYPE, AND MORE ESPECIALLY OF THE GROUP OF NATURALLY OCCURRING PRODUCTS SUCH AS LINSEED, TALL, TUNG AND CASTOR OILS, TURPENTINE AND SIMILAR WOOD ROSINS. THESE, WHEN DISPERSED IN WATER TO PROVIDE STABLE EMULSIONS, ARE USED AS A PRETREATMENT BATH FOR PLASTIC SUBSTRATES, PRIOR TO PLATING OF THE SUBSTRATE, IN ORDER TO PROMOTE THE FORMTAION OF A STRONGER BOND BETWEEN THE METAL PLATE AND SUBSTRATE.

    Abstract: A procedure is disclosed for modifying the topography of the surface of a polymer substrate to improve the bonding capability of the surface of the polymer in respect to subsequently applied coatings such as metal films, paints and inks. The procedure involved comprises first laminating a sacrificial, anodized metal foil to the substrate surface by heat and pressure, chemically stripping away that foil and then developing preferably, by a supplemental chemical stripping treatment, a network of microscopic fissures and cracks which is believed to incipiently form in the surface by the laminating process. Thereafter the treated substrate may be activated and electrolessly plated by conventional methods, followed by an added electrolytic or electroless plating if desired, to provide a metal film of execellent adhesion. Alternatively, standard vacuum metallizing procedures may be used to provide the initial or finished metal coating. Adhesion of other, nonmetallic, coatings such as paints and inks is also improved by the process.
