Abstract
A method for producing a coated chromium-containing component includes providing a coating mixture of a solvent and a source of praseodymium and/or a source of terbium, contacting the surface of the component with the coating mixture, optionally drying, and heating the component in an oxidising atmosphere at a temperature of 450° C. or higher. Examples include coated components for a device, and electrochemical devices with coated components, the components having a surface coating including at least one layer that includes a praseodymium material and/or terbium material. The method produces coatings that reduce chromium evaporation and are useful as barriers on a chromium-containing components.
