    摘要: An HS-PVD (high speed physical vapor deposition) or cold spray method for coating a substrate with a bonding agent layer is provided. This method includes generating a particle stream of a coating material, depositing the particle stream on the substrate and subjecting the substrate to a subsequent thermal treatment, wherein powder particles with a larger particle size are added to the particle stream. A device for implementing the method is also provided.

    摘要: A system for bonding layers (1) of different chemical compositions, such as bonding a thermal barrier layer to a metal substrate on a surface of a gas turbine component. A substrate (4) made either of a ceramic material or particularly of a metal super-alloy may be bonded to an outer layer (16) such as a ceramic by means of a fine-grained intermediate layer (7) bonded to the substrate (4), and a coarse-grained layer (10) bonded to the intermediate layer (7) to create a studded surface (9). The fine and coarse layers (7, 10) provide a transition between the substrate (4) and the outer layer (16) for improved bonding between them. The studded surface (9) may provide at least a 20% increase in bonding surface area for the outer layer (16). Additionally, a medium-grained layer (13) may be applied to the studded surface (9) before applying the outer layer(16).
