Process for producing a coating on a refractory structural member

A process for producing a coating on a refractory structural member, in which a noble metal alloy is applied as a coating material to the refractory structural member. The noble metal alloy contains, among other constituents, an oxidizable substance, which includes boron and/or phosphorus and/or ant...

Beschreibung
Zusammenfassung:	A process for producing a coating on a refractory structural member, in which a noble metal alloy is applied as a coating material to the refractory structural member. The noble metal alloy contains, among other constituents, an oxidizable substance, which includes boron and/or phosphorus and/or antimony and/or arsenic. The refractory structural member and the coating are heated at least once in an oxygen-containing atmosphere to a temperature T that is greater than or equal to the liquidus temperature TL of the noble metal alloy The oxidizable substance is oxidized during this heating process, and the oxide that has formed is at least partially vaporized. The temperature T is maintained until the proportion of oxidizable substance in the coating is
