  • Layered coating system with a MCrAlX layer and a chromium rich layer and a method to produce it
    Patent number: 9222163
    Abstract: A layer system and a method for producing a component having such a layer system are provided. The layer system includes a substrate a substrate, at least one MCrX layer on the substrate, and a chromium-rich layer on or in the at least one MCrX layer. X includes at least one element selected from the group consisting of yttrium (Y), silicon (Si), aluminum (Al) and boron (B). M includes at least one element selected from the group consisting of nickel (Ni) and cobalt (Co).

  • THERMAL BARRIER COATINGS
    Publication number: 20120164473
    Abstract: Coated products are described comprising a metallic substrate, an aluminium-rich layer, a chromia-forming layer and a thermally insulating top coat. The chromia-forming layer is located between the substrate and the thermally-insulating top coat. The aluminium-rich layer is located between the substrate and the chromia-forming layer. The coating may be used to provide protection of parts exposed to conditions of relatively high temperatures, heat flux, and/or corrosive environments, such as the conditions in industrial gas turbines using poorer-quality fuels (such as bio-fuels).
