In this study, tribological properties and surface characteristics of silicone rubber/graphite (QMG) composites were investigated as a function of applied load, sliding velocity (1–5 m/s) and temperature. This study discusses a novel approach to improve the tribological properties of silicone rubber (QM). Inclusion of graphite significantly reduces the friction coefficient (̴40%) and specific wear rate of QM (50%). Wear mechanism involves formation of transfer film at the interphase between composite and steel counter surface. Tribological performance of QMG composites were found to be in agreement with its morphological, mechanical and dielectric properties.

硅橡胶/石墨复合材料摩擦学和力学性能研究

在这项研究中,研究了硅橡胶/石墨 (QMG) 复合材料的摩擦学性能和表面特性,作为施加载荷、滑动速度 (1-5 m/s) 和温度的函数。本研究讨论了一种提高硅橡胶 (QM) 摩擦学性能的新方法。石墨的加入显着降低了 QM 的摩擦系数 (̴40%) 和比磨损率 (50%)。磨损机制涉及在复合材料和钢反面之间的界面处形成转移膜。发现 QMG 复合材料的摩擦学性能与其形态、机械和介电性能一致。
