The study revealed advantages and limitations of the ionitriding process, and documented the production sequences required for the case-hardening of AlSl 4140 and Nitralloy 135M steels. Determination of processing criteria included cleaning, loading, selective case-hardening, treatment times and temperatures, and geometric considerations. The production sequence was established for four weapon components presently manufactured at Rock Island Arsenal. Evaluation of processing times and quality of the case-hardened components revealed that significant advantages are gained when the ionitriding process is used for production.
