摘要： PURPOSE: Provided is 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. CONSTITUTION: The process for producing a coating on a refractory structural member, comprises the steps of: applying a noble metal alloy to a refractory member as a coating material, wherein the noble metal alloy contains a noble metal with a melting point greater than 1,400 deg.C., the noble metal is at least one of platinum, iridium, rhodium, ruthenium and gold the noble metal alloy being used in powder form to coat the refractory member, the noble metal alloy gas a liquidus temperature(TL) of 900 deg.C. to 1,400 deg.C., the noble metal alloy contains 84-99.5 wt.% of noble metal and 0.5 -16 wt. % of the oxidizable substance including at least one of boron, phosphorus antimony and arsenic; heating the refractory structural member and the coating at least once in an oxygen-containing atmosphere to a temperature(T) that is at least equal to the liquidus temperature(TL) of the noble metal alloy; oxidizing the oxidizable substance during the heating step so as to form an oxide that is at least partially vaporized; maintaining the temperature(T) until a proportion of oxidizable substance in the coating is 70 wt.% or more of platinum and 30 wt.% or less of at least one of gold, iridium and rhodium.
