  • ARTICLES WITH NITROGEN ALLOY PROTECTIVE LAYER AND METHODS OF MAKING SAME
    Publication number: 20200407830
    Abstract: Provided are materials that include one or more metals in solid solution with a level of nitrogen that is at a concentration higher than the a solubility limit of nitrogen in the alloy in a liquid state at atmospheric pressure. The materials may be utilized as a protective layer on a substrate, such as an Al containing substrate. Also provided are methods of forming the solid solution materials and articles employing them on a surface of a substrate.
