Abstract

The subject-matter of this Specification is the same as that described in the parent Specification except that the chromium, silicon, and aluminium layer is provided on a body of at least 50% tantalum, instead of niobium, and the preferred composition of the layer (by weight) is 47.5% chromium, 47.5% silicon, and 5% aluminium.
