在650℃的空气中，研究了Cr含量分别为5%、10%和15%，Ni含量为35%的多孔Cu-Ni-Cr合金的氧化行为。结果表明：合金的氧化过程在初始阶段遵循线性规律，然后遵循抛物线速率规律；CuO和Cu2O在合金表面形成了连续的外部水垢。观察到一些内部氧化。此外，随着Cr含量的增加，氧化速率略有下降。
The oxidation behavior of porous Cu-Ni-Cr alloys containing approximately 5,10 and 15 wt.%Cr, but with a similar Ni content of 35 wt.%, was studied at 650°C in air. The results showed that the oxidation of alloys follows linear law at initial stage and then the parabolic rate law. Continuous external scales of CuO and Cu2O formed on the alloys. Some internal oxide of were observed. In addition, with increase of Cr content, the oxidation rate decreased slightly.
