METHOD OF MANUFACTURING AN OXIDATION-RESISTANT COMPONENT OF A MOLYBDENUM BASE ALLOY

摘要

The present invention relates to a method of producing a component of an Mo base alloy which is protected against high-temperature oxidation, and a correspondingly produced component.;The method comprises:provision of a semifinished part composed of a Mo base alloy,provision of an Si-containing slip or of a Si-containing powder,application of the slip to the semifinished part and diffusion annealing of the semifinished part together with the applied slip to form a Si-containing outer layer ortransfer of at least part of the silicon present in the powder via the gas phase to the semifinished part by means of a diffusion heat treatment of the semifinished part together with the Si-containing powder which is arranged at a distance from the semifinished part.
