ABSTRACT In the present study, a lining process for carbon steel using shot peening was investigated to improve the surface properties such as corrosion and oxidation resistances. In the shot lining, a foil set on a metal workpiece is pelted with many hard shots at a high velocity. The foil can be bonded to the surface of the workpiece due to plastic deformation induced by the collision of the shots. In the experiment, an air-type shot peenig machine with an electrical heater was employed. The shot speed and the coverage are controlled in the experiment. The effects of shot conditions and the heating temperature on the bondability were examined. To improve surface properties such as wear resistance and corrosion resistance, alloying of the lined foils was also attempted by heat treatment. The metal foil was successfully bonded to the surface of the substrate. It was found that surface properties of carbon steel could be improved by the shot lining process.
