ABSTRACT:
A method of providing a substrate with a layer of a tertiary compound comprising silicon, silicon carbide and a transition series metal. In accordance with the method, a substrate having at least a surface layer thereon of a transition series metal is coated with silicon carbide particles having an average particle diameter in the range of up to about two microns. The coated substrate is then heated in an inert atmosphere to a temperature between 1000.degree. and 1300.degree. C. for sufficient time to allow diffusion to occur between the silicon carbide and the transition series metal layer, thereby forming the tertiary compound. Substrates coated with the tertiary compound are particularly suitable for preparation of alkali metal/polysulfide batteries wherein the substrate may be exposed to corrosive attack by molten polysulfide salts.
