摘要
主要研究成分及第二相组织对球墨铸钢耐磨性的定量影响规律，从而为合理应用这一新材料和生产中的质量控制提供技术依据。运用正交试验、定量金相、磨损试验及数学回归处理方法，着重探讨碳、硅、铜、铬等成分及石墨与碳化物体积分数对球墨铸钢耐磨性的作用，并得到相关定量关系的数学表达式——回归方程。方差分析表明，试验数据及回归方程是可靠的。
The influence of chemical composition and second phase on wear resistance of cast steel with spheroidal graphites was studied quantitatively to provide technical basis for rational use of the new material and quality control in production.With the help of orthogonal experiment,quantitatively metallography,wear testing and regression analysis,the effect of C,Si,Cu,Cr as well as the volume ratio of graphites and carbides on the wear resistance property of the material was investigated ,and the relative regression equations were obtained.Variance analysis shows that the test data and regression equations are reliable.
