METHOD FOR PRODUCING A heat-resistant coatings on a detail from carbon-free heat-resistant nickel alloys

摘要

A process for preparing a refractory coating of carbon-free heat-resistant nickel alloy member comprising forming carbide barrier layer on the surface of the component in a gaseous carbonaceous medium and subsequent application of the aluminide coating, characterized in that the formation of carbide layer is performed in a vacuum of 10mm Hg 10to and at a pressure of carbonaceous gaseous environment of 0.5 to 10 mm Hg
