本文就铸铁基一碳化钨粒子表面复合层性能进行了研究。试验表明,复合层的磨损速度取决于基体的磨损速度,后者与其硬度有较好的对应关系,但复合层内基体的磨损速度比单一材料小。碳化钨粒子的溶解速度在铸铁中低于钢,它导致界面区成分的变化。可用合金元素来增强粒子与基体的结合,提高复合层的寿命。文中并对试验结果进行了较深入的理论分析。
In this paper, cast iron-based tungsten carbide particle surface composite layer properties were studied. The experimental results show that the wear rate of the composite layer depends on the wear rate of the matrix and the latter has a good corresponding relationship with the hardness, but the wear speed of the matrix in the composite layer is smaller than that of the single material. The dissolution rate of tungsten carbide particles in cast iron is lower than that of steel, which leads to changes in the composition of the interface zone. Available alloy elements to enhance the combination of particles and matrix to improve the life of the composite layer. In the article and the test results conducted a more in-depth theoretical analysis.
