耐磨

Under certain temperature of slurry, the semi-solid microstructure with certain shape and size was obtained, with which both impact toughness and wear resistance of hypereutectic high chromium cast iron were enhanced.

在合适的半固态浆料温度下，可以制备出具有一定尺寸和形状的半固态组织，不仅有利于提高过共晶高铬铸铁的韧性，而且也有利于提高其耐磨性。

The hardness and wear resistance of the RE-Ni-W-P-SiC composite coating increase with the rise of SiC and sodium tungstate concentrations in the bath respectively , while the hardness and wear resistance of the RE-Ni-W-P-SiC coating decrease with increasing sodium hypophosphate concentration in the bath.

随着镀液中次亚磷酸钠浓度的升高，镀层的硬度和耐磨性均降低。

The drawing testing、cutting testing and fracture analysis of high chromium casting iron－carbon steel's compounding interface showed: the compounding interface has higher strength and the impact toughness of composite plate is about 5 times of high chromium casting iron, which make it possible to make full use of high chromium casting iron's excellent wear resistance in practice under the high impactive condition.

需要特别指出的是：复合板的冲击韧性高铬铸铁5倍以上，这为高铬铸铁在高冲击工况发挥其优异耐磨性能提供了可能。采用试验方法生产的双金属复合板件正在矿山冲击较大的工况下使用，实际使用时间已经超过以前使用的高锰钢的使用寿命，目前仍在继续使用中。
