Coating method for a roughend adhesion layer

摘要

The high speed physical vapor deposition or cold spray method for coating a substrate with a bonding agent layer, comprises generating a particle stream (8) of a coating material (15), depositing the particle stream on the substrate, heating the particle stream at 550-650 [deg] C, and adding powder particles (14) with a larger particle size of 45-85 mu m to the particle stream. The particles accelerate on a speed of sound and then added to the particle stream. A turbine blade (9) is coated as substrate with the bonding agent layer. An independent claim is included for a device for coating a substrate with a bonding agent layer.
