The effect of precious metals in the NiAl coating on the oxidation resistance of the Inconel 713 superalloy
The rhodium incorporated aluminide coating was produced by the rhodium electroplating (0.5 ?m thick layer) followed by the chemical vapor deposition process on the Inconel 713 superalloy. This coating is composed of the ?-NiAl phase. A part of nickel atoms is replaced by rhodium atoms in the ?-NiAl phase. The plain, rhodium and platinum incorporated aluminide coatings were oxidized at 1100?C under the atmospheric pressure. The oxidation kinetics of the rhodium and platinum incorporated aluminide coatings are similar, but different than oxidation kinetic of the plain coating. The ?-Al2O3 is the main product both in rhodium and platinum modified coatings after 360 h of oxidation. Moreover, the ?-Ni3Al phase, besides the ?-NiAl phase, was identified. The presence of 4 at. % rhodium in the coating provides similar oxidation resistance as the presence of 10-20 at. % platinum. Both rhodium and platinum incorporated aluminide coatings produced by the chemical vapor deposition process offer good oxidation protection of the Inconel 713 superalloy.
期刊介绍：
University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded.
Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
