ABSTRACT:
An epsilon iron nitride surface layer of high surface wear resistance is formed on a steel component by gas nitriding or nitrocarburizing and, according to the invention, includes the preliminary step of heating the component to the nitriding temperature in an atmosphere which is inert to the metal of the component.
