摘要
利用ZHW-600A真空非自耗电弧炉熔炼制得不同Ce含量的Cu-0.8Cr-Ce合金,制成薄板后进行了包埋内氧化处理,并对其反应动力学方程进行了计算和研究。结果表明:当内氧化温度一定时,内氧化时间与内氧化层深度呈抛物线关系;少量Ce的加入加速了Cu-0.8Cr合金的内氧化进程,Cu-0.8Cr-0.2Ce合金在950℃内氧化12 h后层深可达772μm;计算可得其内氧化动力学方程。
Cu-0.8Cr-Ce alloy with different content of Ce was smelted using ZHW-600A nonconsumable vacuum arc furnace.The embed internal oxidation treatment of these alloy sheet was carried out.The internal oxidation reaction kinetics was investigated and calculated.The results show that,when the internal oxidation temperature keeps constant,the relationship between internal oxidation time and internal oxidation layer thickness is parabolic.The internal oxidation process of Cu-0.8Cr alloy is accelerated by trace addition of rare earth element Ce,and the internal oxidation layer of Cu-0.8Cr-0.2Ce alloy sheet can be up to 772 μm at 950 ℃ for 12 h.According to the experimental data,the dynamical equation of Cu-0.8Cr-0.2Ce alloy is calculated and expressed.
