研究了粉末冶金三元双相Cu-44%Cr-12%Fe(质量分数)合金在800℃时不同氧分压下的氧化行为.结果表明:Cr含量为44%时合金在1.01×105 Pa的纯氧中并不能形成连续的外Cr2O3膜,合金的氧化速度随氧分压的降低而降低,原因是低氧分压有助于抑制合金中Cr的内氧化并形成连续致密的Cr2O3膜.讨论了氧化膜的形成机制. |

The oxidation behavior of a two-phase ternary Cu-44/'oCr-12%FeCmass fraction) alloy prepared by pow-der metallurgy (PM) was studied at 800 V under three different oxygen pressures. The surface of alloy with 44%Cr cannot produce a continuous external chromia when pressure of oxygen is 1. 01X105 Pa, and the reduction of the ox-idation rates at lowered oxygen pressures is obviously attributed to the formation of a continuous and compacted chromia scale. Finally the oxidation formation mechanism under different oxygen pressures was discussed. |
