| 摘 要： | 通过冲击试验和磨损试验,研究了钨含量对淬火回火高铬铸铁性能的影响。结果表明,热处理对钨元素的分布影响不大,钨在基体和碳化物中均匀分布。随钨含量增加,淬火回火高铬铸铁硬度增加,冲击韧度和耐磨性先升高后降低。高铬钨铸铁硬度为62～65 HRC,冲击韧度为6～8 J/cm2,一定量钨的加入能显著提高高铬铸铁的耐磨性。

| Abstract: | Effect of tungsten on properties of as-quenched-tempered high chromium cast iron were studied by mechanical properties and wear resistance testing.The results show that heat treatment hardly has any effect on the distribution of tungsten.The distribution of W is uniform in matrix and carbides of high chromium cast iron.With W content increasing,the hardness increases,the impact toughness and the wear resistance increases first and then decreases.The hardness and impact toughness of the high chromium tungsten cast iron are 62-65 HRC and 6-8 J/cm2.The wear resistance of high chromium cast iron increases obviously with tungsten addition. |
