    Abstract: The invention relates to a protective layer for the protection of a component against corrosion and oxidation at elevated temperatures. Previously known protective layers with a high Al and/or Cr content, which are additionally reinforced with Re, form brittle phases that embrittle further during use due to the influence of carbon. The inventive protective layer is composed of 0.5 to 2 percent rhenium, 24 to 26 percent cobalt, 15 to 21 percent chromium, 9 to 11.5 percent aluminum, 0.05 to 0.7 percent yttrium and/or at least one equivalent metal from the group comprising scandium and the rare earth elements, 0 to 1 percent ruthenium, the remainder consisting of cobalt and/or nickel and production-related impurities. Said protective layer is subject to hardly any embrittlement resulting from Cr/Re precipitations.

    Abstract: Procedimiento para el revestimiento de un sustrato (1), que presenta al menos un orificio (4), en el que en una primera etapa el al menos un orificio (4) se cubre con un tapón (16), en otra etapa se aplica al menos una capa(13) sobre una superficie (3) del sustrato (1), tratándose en el caso del procedimiento de aplicación para la capa (13) de un procedimiento de revestimiento a bajas temperaturas, que se encuentran por debajo de 250°C, especialmente por debajo de 100°C, y en otra etapa tiene lugar una irradiación de una superficie (15) de la al menos una capa (13), de modo que se proporciona una mejor adherencia y homogeneización de las partículas en la zona próxima a la superficie de la capa (13).

    Abstract: Highly oxidation resistant components as known in state of the art disclose a MCrAlY layer, which shows a poor anchoring between the thermal barrier coating and the oxide layer on the MCrAlY layer. The inventive heat resistant component (1) discloses a MCrAlY layer (16), which has an outer layer (19) of the composition of ²-NiAl or ³-Ni, so that a meta-stabile aluminium oxide is formed, which leads to a good anchoring of the thermal barrier coating (13) to the thermally grown oxide layer.
