    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.

    摘要: To protect a base metal layer (1) against high-temperature corrosion and high-temperature erosion, an adhesive layer (3) based on MCrAlY is applied to the base metal layer (1). The adhesive layer (3) is coated with an Al diffusion layer (4) by alitizing. The diffusion layer (4) is subjected to an abrasive treatment, so that the outer built-up layer (4.2) on the diffusion layer (4) prepared by alitizing is removed by the abrasive treatment. A ceramic heat insulation layer (2) consisting of zirconium oxide, which is partially stabilized by yttrium oxide, is applied to the diffusion layer (4) thus treated.

    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: This invention relates to the simultaneous treatment of the internal and external surfaces of turbine blades or vanes. In particular it provides a process for coating an external and an internal surface of a turbine blade or vane with aluminium and chromium, respectively, at substantially the same time. The process comprises the following steps (i) and (ii) in either order: (i) applying to the external surface an aluminising compound comprising aluminium, a moderator, an energiser and a diluent; and (ii) applying to the internal surface a chromising compound comprising chromium, an energiser and a diluent. These steps are followed by (iii) heating the turbine blade or vane to form an aluminium layer on the external surface and a chromium layer on the internal surface. The invention also provides a suitable aluminising compound and a chromising compound per se.
