Abstract (en)

A metallic coating is formed on a refractory metal substrate, e.g. for providing corrosion resistance, by providing an initial porous metallic coating on the substrate by spraying and then heat treating, e.g. by HF heating, to sinter at least part of the initial coatings and give rise to diffusion into the substrate. Working, e.g. by warm rolling, is carried out to densify the coating. The resulting coating is ductile and may, for example, be of an Al-bearing ferritic steel such as a steel having up to 8% by weight Al and/or up to 25% by weight Cr. The substrate may, for example, be a steel such as stainless steel.
