This is the first study ever to show the impact of high-energy 160 MeV xenon ion irradiation on the properties of 100Cr6 bearing steel. The projected range (R) of xenon ions is 8.2 µm. Fluence-dependent variations in the coefficient of friction and wear of the 100Cr6 steel material have been observed. These changes correlate with shifts in the crystal lattice constant and variations in the oxygen, carbon, and iron content in the wear track. Fluence-dependent changes in these parameters have been observed for the first time. Irradiation reduces stresses in the crystal lattice, leading to crystallite size increase. The modifications in the properties of 100Cr6 steel result from radiation-induced defects caused by electronic ion stopping. The degree of these modifications depends on the applied irradiation fluence. Furthermore, the use of a higher irradiation fluence value appears to mitigate the effects produced by a lower fluence.
这是有史以来第一项展示高能160 MeV氙离子辐照对100Cr6轴承钢性能影响的研究。氙离子的投影射程（R）为8.2 µm。已观察到100Cr6钢材料的摩擦系数和磨损随注量的变化。这些变化与晶格常数的变化以及磨损轨迹中氧、碳和铁含量的变化相关。首次观察到这些参数随注量的变化。辐照降低了晶格中的应力，导致微晶尺寸增加。100Cr6钢性能的改变是由电子离子阻止引起的辐射诱导缺陷所致。这些改变的程度取决于所施加的辐照注量。此外，使用较高的辐照注量值似乎可以减轻较低注量产生的影响。
