| 中文摘要 | The oxidation behavior of a binary Cu-7Cr and a ternary Cu-7Cr-4Al alloy has been studied at 1173K in 0.1 MPa O-2 and compared with that of a binary Cu-4Al alloy. Oxidation of Cu-7Cr produced external copper oxide scales, while the internal oxidation of chromium was almost absent. The addition of 4 at.% Al to Cu-7Cr formed an alumina layer in contact with the alloy after an initial faster stage when also copper was oxidized. Cu-4Al also formed an alumina layer, but the scale thickness was irregular due to the presence of oxide nodules, while the long-term rate constant was larger than for the ternary alloy. Thus, the addition of chromium to Cu-4Al had a beneficial effect by suppressing the formation of nodules and by reducing the steady-state parabolic rate constant. Conversely, the addition of aluminum to Cu-7Cr prevented the oxidation of copper, producing a large decrease of the oxidation rate. |
