ABSTRACT:
Rust is removed from the surfaces of metallic objects by focusing a laser beam on successive increments of the surface so that the beam causes evaporation of rust. The laser is a gas laser and is designed to effect pulsed emission of coherent radiation. The output power of the laser is selected in such a way that the beam cannot melt or evaporate the parent metal.
