WC/Mn13堆焊复合材料磨料磨损性能的研究

Study of Abrasive Wear Resistance of WC / Mn13 Cumulate-welding Composites

采用堆焊工艺在高锰钢的基体表面复合上一层WC硬质合金材料,获得了一种具有高耐磨性和高韧性的复合材料。对WC/Mn13堆焊复合材料的微观组织、力学性能以及耐磨料磨损性能进行了研究分析,结果表明:高锰钢堆焊复合材料与传统耐磨材料相比表现出了优越的耐磨料磨损性能,并保持了高锰钢高韧性的特点,综合性能极大提高。

Using cumulate-welding technology, a layer of WC hard metal was compounded on the matrix surface of hadfield steel, and high wear resistance and high toughness WC/Mn13 composites was successfully fabricated, Microstructure, mechanical properties and abrasive wear resistance of WC/Mn13 cumulate-welding composites were studied and analyzed. The results show that, compared with traditional wear-resistant materials, the abrasive wear resistance of WC/Mn13 cumulate-welding composites is predominant, and its toughness characteristic also remains.
