摘要: 为提高镍基和铁基合金粉喷熔层的耐磨性和耐热疲劳性能,在现有的Fe60E和Ni60A喷熔合金粉中加入1.5%~1.8%的V制成新型喷熔材料Fe60EV和Ni60AV。试验测定了Fe60EV和Ni60AV喷熔层的硬度、耐磨性和抗热疲劳性能,结果表明,含钒喷熔合金层的硬度比未加钒的喷熔合金层的高,其耐磨性和耐热疲劳性能也明显提高。在热轧卷取机衬板上的工业应用表明,喷熔Fe60EV和Ni60AV合金层后,其使用寿命分别比喷熔Fe60E和Ni60A提高30%以上。Abstract: In order to improve the wearablility and spalling resistance of Fe60E and Ni60A spraying alloy layer, two new spraying alloys named Fe60EV and Ni60AV are developed by add 1.5%~1.8% V into Fe60E and Ni60A spraying alloy.The hardness,wearablility and spalling resistance of the new spraying alloy layers are tested in laboratory.The results show the properties of Fe60EV and Ni60AV spraying layers are better than that of Fe60E and Ni60A spraying layers,that is the hardness is higher and the wearablility and spalling resistance are improved obviously.The Fe60EV and Ni60AV as well as Fe60E and Ni60A are sprayed on the backing block of an industrial hot rolled coiler respectively.The practical results show the service life of the backing block sprayed Fe60EV and Ni60AV alloy layers prolongs over 30% than that of sprayed Fe60E and Ni60A spraying alloy layers respectively.
