关于铸铁氧化性能参数的讨论

The Approach on the Oxidation of Cast Iron

在分析讨论铸铁性能参数的基础上,对常用的氧化参数——氧化增重及氧化层厚度的实验方法作了一些改进.经反复验证,认为采用改进的实验方法评价铸铁的氧化性能,可以得到比较精确的结果.最后还提出了新的氧化参数——氧化蚀掉深度的实验方法以及抗氧化性指标——氧化参数倒数的概念.

The author analyses and discusses the oxidizing parameter of cast iron and then makes an improvement upon the experimental metheod of ordinarily used experimental parameters - the weight gain of oxidizing and the thickness of oxidized layer. Through the test a precise result may be obtained using the improved method to evaluate on oxidizing propertoes of cast iron. At last, the paper presents the experimental steps of new oxidixing paramenter-oxidixed cotrosive depth and the conception of anti-oxidizing index-the reciprocal of oxidizing parameters.
