Exploring ways to improve the performance of rotating bands is of great importance for enhancing the power of modern artillery. This study prepared graphene oxide-coated Nylon (GO-Nylon) and Nylon samples based on nylon rotating bands in artillery systems to investigate the feasibility of introducing GO-coated nylon rotating band materials to enhance their tribological and thermal properties. The friction behavior and thermal effects of these two surfaces were analyzed under different external loads and surface roughness conditions. The results show that the excellent thermal conductivity of GO effectively reduced temperature accumulation during friction. Under an external load of 8 N, the surface temperature of GO-Nylon decreased by 14% compared to the Nylon surface, and the coefficient of friction (COF) decreased by 21%. At the same time, a simulation model was established, and its calculation results were consistent with the experimental trends, providing a further explanation of the experimental phenomena. This research provides a basis for the application of graphene-based coatings in the defense industry and presents new ideas for the development of high-performance rotating band materials.
探索提高旋转带性能的方法对于增强现代火炮的威力至关重要。本研究基于火炮系统中的尼龙旋转带制备了氧化石墨烯包覆尼龙（GO-Nylon）和尼龙样品，以研究引入GO包覆的尼龙旋转带材料来增强其摩擦学和热性能的可行性。在不同的外部载荷和表面粗糙度条件下，分析了这两种表面的摩擦行为和热效应。结果表明，GO优异的热导率有效地减少了摩擦过程中的温度积累。在8 N的外部载荷下，GO-Nylon的表面温度比尼龙表面降低了14%，摩擦系数（COF）降低了21%。同时，建立了一个模拟模型，其计算结果与实验趋势一致，为实验现象提供了进一步的解释。本研究为石墨烯基涂层在国防工业中的应用提供了依据，并为高性能旋转带材料的开发提出了新思路。
