Abstract:
Identifiers Pack cementation, Hot dipping.A summary is presented of the current state of the art of coatings to protect refractory metals from oxidation. Coatings for Mo are the most advanced, followed by those for Nb alloys. Significant progress was made on coatings for Ta alloys. W has received some attention, but the temperature range precludes any easy solutions. No coatings are available for V alloys. Silicide-base coatings are of most importance for Mo and W. Both the aluminide and silicide-base coatings were of genuine value for the protection of Nb and Ta alloys.
