作者详细地考察了合金元素和摩擦学条件等因素对中频感应熔炼、精铸成型法制备的Ni-Nb-Fe-Se合金之摩擦磨损性能的影响,并且利用X-射线衍射仪和电子显微镜(配EDAX)等对合金的相结构和显微组织,以及几种试验条件下合金试样的磨损表面形貌进行了分析。结果表明,只要合金所含的Nb和Se适量,其在较宽的温度范围内就会具有较低的摩擦系数和较高的耐磨性。作者认为,Ni-Nb-Fe-Se合金中的NbSe_2块状组织和NbxSe_2(x=1.00～1.10)条状组织对改善合金的摩擦学性能起着至关重要的作用。
The effects of alloying elements and tribological conditions on the friction and wear properties of Ni-Nb-Fe-Se alloys prepared by IF induction melting and casting are investigated in detail. The effects of XRD and SEM (electron microscopy) With EDAX), etc. The phase structure and microstructure of the alloy, as well as several test conditions, the wear surface morphology of alloy samples were analyzed. The results show that as long as the alloy contains Nb and Se appropriate amount, it will have a lower friction coefficient and higher wear resistance over a wide temperature range. The authors believe that the NbSe_2 bulk structure and the NbxSe_2 (x = 1.00 ~ 1.10) strip structure in Ni-Nb-Fe-Se alloy play an important role in improving the tribological properties of the alloy.
