| 摘 要： | 为了提高铸件表面的耐磨性，实验以低铬铸铁为基体，WC颗粒为增强体，制备出颗粒增强表面耐磨复合材料。实验结果表明：低铬铸铁基复合材料的显微组织分三层，它们依次是基体、过渡层、复合层；其硬度比高铬铸铁略低．而耐磨性却略高于高铬铸铁。

| Abstract: | In order to improve the abrasion-resistant on the casting surface,the low-Cr cast iron matrix composite reinforced by WC particles in sand mold was made in the experiment.The experimental results show that the microscopic structure of the composite has 3 layers:base,transition,and composite layer.The hardness of composite is lower than high-Cr cast iron,but its abrasion resistant is better than high-Cr cast iron. |
