    Abstract: Compounds of formula: Al wCo xM yare new. M is Ni and/or Cr and at least 30 mass% of the compound has a quasi-crystalline structure. W = 70 - 76 and w + x + y = 100. Independent claims are included for: (A) coatings made form or containing the compounds; (B) coating systems containing a coating made from the compounds; (C) multi-layer coating systems containing two or more of the coating systems; (D) use of the compounds as heat-insulating coatings for components subjected to high temperature, especially turbine steam inlets (333) and blades (357); and (E) use of compounds containing aluminum and manganese, at least 30 mass% of the compound having a quasi-crystalline structure, for the same purpose.

    Abstract: The invention relates to a product (1), in particular a gas-turbine blade (1), having a metallic basic body (2) to which a protective layer (3, 4) for protecting against corrosion is bonded. The protective layer (3, 4) has an inner layer (3) of a first MCrAlY alloy and an outer layer (45) having a second MCrAlY alloy, which is bonded to the inner layer (3). The second MCrAlY alloy is predominantly in the gamma-phase. The invention also relates to a process for producing a protective layer (3, 4) in which the outer layer (4) is produced by re-melting a region of the inner layer (3) or by deposition of an MCrAlY alloy from a liquid phase.
