    摘要: A method is provided for coating a hollow, internally cooled blade (1) of a gas turbine, in which method an outer coating (5) comprising an MCrAlY-based bonding layer (6) and a ceramic thermal barrier layer (9) of zirconium oxide is applied to the base material (3) of the blade (1) on the outer side of the blade (1) and an inner coating (4) comprising a Cr diffusion layer (7) is applied to the base material (3) of the blade (1) on the inner side of the blade (1). The MCrAlY-based bonding layer (6) is thereby applied to the finished blade (1). At the same time, along with the inner coating (4), the Cr diffusion layer (7) is also applied to the MCrAlY-based bonding layer (6) of the outer coating (5) by chemical vapour deposition. Subsequently, an Al diffusion layer (8) and an outer brittle Al build-up layer are applied by chemical vapour deposition to the bonding layer (6) coated with the Cr diffusion layer (7). After that, the outer brittle Al build-up layer is removed by an abrasive treatment and the ceramic thermal barrier layer (9) is applied to the Al diffusion layer (8).

    摘要: Disclosed is a heat-insulating protective layer for a component located within the hot gas zone of a gas turbine. Said protective layer is composed of an adhesive layer, a diffusion layer, and a ceramic layer which is applied to the high temperature-resistant basic metal of the component. The adhesive layer comprises a metal alloy [MCrAlY (M=Ni, Co)] containing Ni, Co, Cr, Al, Y, the diffusion layer is produced by calorizing the adhesive layer, and the ceramic layer is composed of ZrO2 which is partially stabilized by means of yttrium oxide. One or several chemical metal elements that have a large atomic diameter and are selected among the group comprising Re, W, Si, Hf, and/or Ta are alloyed to the material of the adhesive layer. The adhesive layer has the following chemical composition after being applied: Co 15 to 30 percent, Cr 15 to 25 percent, Al 6 to 13 percent, Y 0.2 to 0.7 percent, Re up to 5 percent, W up to 5 percent, Si up to 3 percent, Hf up to 3 percent, Ta up to 5 percent, the remainder being composed of Ni.

    摘要: A method for applying a protective layer resistant to high-temperature degradation by corrosion and erosion to a base metal, comprises: applying a MCrAlY-based bond layer to the base metal; coating, by overaluminizing with an Al diffusion layer, the bond layer; subjecting the Al diffusion layer (14) to abrasion treatment so that an outer build-up layer is removed from the Al diffusion layer; and applying a ceramic thermal barrier coating of yttria partially stabilized zirconia to the remaining Al diffusion layer. The ceramic thermal barrier coating is applied to the remaining Al diffusion layer by air plasma spraying. The applied bond layer is subjected to a polishing treatment before being overaluminized such that a surface roughness of Ra≦2 μm is produced at the bond layer.
