BESCHICHTUNG FUER EIN SUBSTRAT UND VERFAHREN ZU DESSEN HERSTELLUNG

摘要

To obtain a pore-free and firmly adhering coating, which is durable even at high temperatures, for a substrate, especially of a refractory metal, it is proposed that the coating consists of aluminium silicate. A process for producing such a coating is also proposed. According to this process, the coating material is introduced in powder form into a plasma jet generated by means of a plasma burner and then deposited on the substrate. While this is being done, the plasma burner and the substrate are held in a reduced-pressure environment.
