Abstract

A refractory metal, e.g. niobium, molybdenum, tungsten, tantalum and vanadium, or alloys thereof, are given an oxidation resistant diffusion alloy coating using a molten alkaline earth metal (calcium, strontium or barium) as a transfer medium and one or more diffusing elements from one or both of the groups: (1) silicon and aluminium, and (2) transition elements having at least one but less than 10d electrons, e.g. titanium, manganese, iron, cobalt, nickel, yttrium, zirconium, vanadium, chromium, molybednum, niobium, tantalum, and tungsten. The transfer medium may be 25-99.5% (preferably 35-65%) by weight of the coating composition. Copper and zinc may be used to dilute the composition. Specified refractory alloys are 80% Nb, 10% Mo, 10% Ti; and 95% Nb, 5% Zr.
