METHOD FOR PRODUCING AN OXIDATION-RESISTANT COMPONENT FROM A MOLYBDENUM BASE ALLOY

摘要

The present invention relates to a method for producing a component made of a Mo-based alloy that is protected against high-temperature oxidation, and a correspondingly produced component, the method comprising the following steps: providing a semi-finished product made of an Mo-based alloy, providing a Si-containing slip or containing powder, applying the slip to the semifinished product and diffusion annealing of the semifinished product with the applied slip to form an Si-containing outer layer or transferring at least part of the silicon contained in the powder via the gas phase to the semifinished product by diffusion heat treatment of the semifinished product with the spacing from the semifinished product, but arranged next to the semi-finished Si-containing powder.
