Corrosion of tungsten-base pseudoalloys in elegas

Conclusions Pseudoalloys based on tungsten and copper (silver) possess good resistance to corrosion by dry elegas, and may be recommended for the manufacture of electrical parts intended for operation in hermetic systems filled with elegas. In humid elegas pseudoalloys based on tungsten and copper (silver) become covered with films forming by the reactions of the surfaces of these materials with water and the hydrolysis products of impurities in elegas.Translated from Poroshkovaya Metallurgiya, No. 10(214), pp. 40–43, October, 1980.
