  • Publication number: 20050123683
    Abstract: A method and apparatus for improving the corrosion resistance of chrome plated materials. After the materials to be chrome plated are mechanically abrasively polished, but before they are reverse etched, they are power washed with a high-pressure liquid. A sprayer with nozzles directed inwardly towards the materials directs water onto the material at pressures in the range of 1000 or 2500 to 3000 psi. After the materials are chrome plated, they are heated above the melting point of a buffing compound, and then the heated materials with the buffing compound applied are buffed. An induction heater is used, before or after the buffing compound is applied. Computer controls, responsive to operator input of the cross-sectional size, composition and/or speed of movement of the chrome plated materials, to in turn regulate the power to an induction coil heater.
