Process and apparatus for coating a product, especially a high temperature gas turbine component

摘要

The coating device has a vacuum chamber for applying a metal layer to the surface of the gas turbine component after its initial heating to a temperature above room temperature, with the coated gas turbine component fed through a subsequent heat treatment stage. The temperature of the metal coated gas turbine component before the heat treatment is at least equal to a minimum temperature (Tmin) above normal room temperature, e.g. above a minimum temperature of between 900 and 1400 degrees K.
