Oxidation behavior of a double-layer iridium-aluminum intermetallic coating on iridium at the temperature of 1400 °C–2000 °C in the air atmosphere
Source abstract
Abstract
Abstract Iridium (Ir) does not form a protective oxide barrier in high-temperature oxidizing environments, leading to a limited lifetime at high temperatures. To improve the oxidation resistance, pure Ir was modified by pack cementation to produce a double-layer iridium-aluminum (Ir-Al) coating. The oxidation behavior investigation on the Ir-Al coatings at temperatures from 1400 °C to 2000 °C demonstrated that the oxidation resistance of the Ir were significantly enhanced after the pack cementation treatment. Further detailed studies showed that the morphology and mass loss of the oxidized Ir-Al coating are considerably affected by the melting and oxidation of the IrAl2.7(3).
