Abstract

A method of using laser energy for treating a metal work-piece to modify chemical properties of a surface of the metal work-piece. The method includes the step of applying a material to a surface of a metal work-piece. The material is corrosive with respect to the surface. The method also includes the step of improving a resistance to corrosion of the surface by initiating a chemical reaction between the corrosive material and the surface with a laser.
