Abstract

Mechanical components, e.g. piston rods for hydraulic cylinders, made from metal with a chromium coating have an intermediate coating of nickel-phosphorus. An independent claim is included for a method for producing the components by electrolytic coating in a bath of electrolyte containing nickel and phosphorus, followed by electroplating with chromium.
