Abstract
An article for use at high temperatures and in corrosive environments comprising a substrate of refractory metal or alloy thereof. The substrate is coated with an interlayer followed by an optional preliminary coating and a final coating of a platinum group metal. The interlayer reduces oxidation of the substrate and prevents metallic interdiffusion between the final coating and substrate contributing both to an improved tolerance of the article to the working environment and reduced manufacturing costs.
