Description
Summary:This literature review focuses on the nitriding treatments of nickel-based superalloy UNS N07718, also called INCONEL 718. This alloy was selected due to the relevance of this alloy in the aerospace and oil and gas industries. The referenced studies reflect a clear trend towards improving superalloys through advanced nitriding processes, highlighting plasma nitriding as one of the most promising techniques to enhance alloy 718 against corrosion and wear. The importance of optimizing nitriding parameters, such as temperature and time, is emphasized to increase wear and corrosion resistance while minimizing adverse effects like delamination or the formation of undesirable phases. Finally, the most appropriate alternatives for future research are recommended.
