Abstract: A process for chrome plating magnesium and its alloys. The process uses a combination of electroless nickel plating, a multi-stage copper coating transition system and multiple layers of electrodeposited nickel to form a corrosion resistant system of substantial impermeability and interlayer adherence suitable for direct chromium electroplating.

Abstract: An improved method for plating and metallizing plastic articles is disclosed. A polymer is selected to mold a three-dimensional plastic article for use with miniaturized electronic devices. Patterns are structured onto the surface of the plastic article by means of laser direct structuring or by multi-shot injection molding. The patterns on the plastic article are activated with a colloidal palladium solution. The activated patterns are then plated with copper and nickel using electroless baths. Optionally, the patterns are flash gold plated to improve bonding, solderability and contact resistance.
