[origin: WO9503905A1] A casting process is disclosed for producing a workpiece, in particular a piston, made of two different materials. In order to solidly bind the base material and a second material, the piece to be cast is galvanically provided before casting with a chromium-containing layer and is then moulded by an Alfin process.
