摘要
对加入稀土（质量分数，％）La0～0．087的GH230合金进行了1000℃恒温氧化实验。实验结果表明：适量La能有效地提高GH230合金的抗氧化能力和增强表面氧化膜的剥落抗力。但当合金中La含量达到0．087％时，合金中析出富La相会降低其氧化抗力。
The influence of La content on isothermal oxidation behavior of GH230 alloy at 1 000℃ in air was investigated. La improves not only the oxidation resistance, but also enhances oxide spallation resistance of the alloy when the content of La is from 0 to 0. 087% （mass percent）. A La-riched phase was precipitated in the GH230 alloy with 0. 087% （mass percent） La, which showed a negative effect on the oxidation resistance of this alloy.
