Method and device for coating a product

The invention relates to a method of coating a product with a metallic coating, in particular with a metallic anti-oxidation coating, in a vacuum plant. In the method, the product is fed into the vacuum plant and heated from room temperature to a product temperature, the metallic coating is applied to the product, and the coated product is subjected to a postheat treatment. Furthermore, the invention relates to an apparatus for coating a product with a metallic coating in a vacuum plant, the vacuum plant including a coating chamber and a postheat treatment chamber. A method includes coating a product with a metallic coating, in particular a high-temperature component product of a gas turbine, in a vacuum plant. An apparatus coats the product with a metallic coating in a vacuum plant, having a coating chamber and a postheat treatment chamber. Novel process control with regard to a temperature profile, in particular after the application of the metallic coating to the product and before the postheat treatment, involves the ensuring of a minimum temperature at all times, this minimum temperature being relatively higher than room temperature.
