In order to obtain a permanent, pore-free and firmly adhering coating for a substrate, especially for a substrate made of a refractory metal, it is proposed that the coating consist of aluminum silicate. A method for producing such a coating is also proposed. According to this method, the coating material is introduced in powder form into a plasma jet generated with the aid of a plasma torch and then deposited on the substrate. The plasma torch and the substrate are kept in a vacuum environment. |
