中文摘要:
      为了探究醇类物质在高载高速工况下的润滑性能,尤其是碳链、羟基与润滑性能的关系,开展了碳链长度、羟基数目对醇类物质润滑性能影响的研究。利用四球摩擦机调查一系列醇类物质的摩擦学性能,结合黏度仪、透射电镜和拉曼等检测手段,探索碳链长度、羟基数目对润滑性能的影响。实验结果表明,随着碳链的增长磨合期变短、摩擦系数达到稳态的时间变短、磨损率降低;随着羟基数目的增多磨损率降低、无明显磨合期和摩擦系数持续波动(乙二醇)或持续降低(甘油)。摩擦诱导形成的石墨烯较无定形碳更能有效地促使摩擦体系达到稳定的摩擦系数,缩短磨合期,研究结果可为醇类物质在机械设备领域的应用提供参考。
英文摘要:
      In order to explore the lubrication performance of alcohols under high loads and high speeds conditions, especially the relationship between carbon-chain length and hydroxyl number and lubrication performance, the effects of carbon-chain length and hydroxyl number on the lubrication performance were well studied. The tribological properties of a series of alcohols were investigated by a four-ball tribological machine, and the effects of the carbon-chain length and the hydroxyl number on their lubricating properties were investigated by means of viscometer, transmission electron microscopy (TEM) and Raman. Experiments show that with the increasing of the carbon-chain length, the run-in period and the time for achieving stable friction coefficient were shorted, and the wear was reduced; with the increasing of the hydroxyl number, the wear decreased with no obvious run-in period and consistent fluctuation of friction coefficient for ethylene glycol and continuous decrease of friction coefficient for glycerol. It is found that friction-induced graphene is superior to amorphous carbon in effectively promoting the tribosystem to achieve the stable friction coefficient and shorten run-in period, which provides reference for the application of alcohols in the field of mechanical equipment.
