Purpose This specification covers the engineering requirements for producing a continuous thin epsilon-iron-carbonitride compound layer on parts by means of a gaseous@ low temperature carbon enriched nitriding process. The process is intended to utilize an atmosphere of high nitriding potential that produces a compound layer. If the compound layer is intended to be controlled automatically@ AMS2759/12 shall be used. Application This process has been typically used to increase resistance to wear and fatigue and to improve corrosion resistance on ferrous metals@ such as carbon@ low-alloy@ and tool steels@ and cast irons@ but usage is not limited to such applications. This process can be selectively applied to wear areas of the component (see 8.5).
