Cu－50Cr合金在700—900℃空气中的氧化结果表明，合金的氧化动力学在700和800℃遵循抛物线速度规律，在900℃其瞬时抛物线速率常数随时间而降低．合金氧化外层膜是CuO和Cu2O，内层膜由氧化铜和尖晶石型氧化物为基并嵌有Cr颗粒组成，Cr表面有Cr2O3和Cu2Cr2O4膜。900℃的氧化膜与基体金属界面上可观察到连续的Cr2O3层.合金未形成Cr的选择性外氧化．
The oxidation results of Cu-50Cr alloy in air at 700-900 ℃ showed that the oxidation kinetics of the alloy follow the parabolic velocity law at 700 and 800 ℃, and its instantaneous parabolic rate constant decreases with time at 900 ℃. The outer oxide film of the alloy is CuO and Cu2O, the inner film is composed of copper oxide and spinel type oxide and embedded with Cr particles, and Cr2O3 and Cu2Cr2O4 films are arranged on the surface of Cr. A continuous layer of Cr2O3 was observed on the interface between the oxide film and the base metal at 900 ° C. The alloy did not form a selective oxidation of Cr.
