    • [Summary][Object] To provide a low-friction sliding mechanism capable of exhibiting an extremely excellent ultra-low friction characteristics at a sliding face existing in a variety of uses.[Solving means] A low-friction sliding mechanism is constituted by disposing a lubricant containing glycerol, at a sliding face formed between sliding members which have respectively hard carbon thin films. A low-friction sliding mechanism is constituted by disposing a lubricant containing hydroxyl group, at a sliding face formed between sliding members which have respectively hard carbon thin films, wherein a friction coefficient of smaller than 0.02 is exhibited in a sliding contacting condition under a boundary lubrication which exhibits a friction coefficient of 0.1 to 0.14 at a sliding face between a steel and a steel in presence of an engine oil. Each hard carbon thin film is formed of a-C or ta-C. Each hard carbon thin film has a hardness of 1500 to 5000 Hv in micro-Vickers hardness under a load of 10 g. Each hard carbon thin film has a film thickness of 0.3 to 2.0 μm. The lubricant containing hydroxyl group is one of alcohols, and is glycerol.
    • 发明内容提供一种能够在存在各种用途的滑动面上表现出非常优异的超低摩擦特性的低摩擦滑动机构。 解决方案低摩擦滑动机构是通过在分别具有硬碳薄膜的滑动部件之间形成的滑动面上设置含有甘油的润滑剂构成的。 低摩擦滑动机构是通过在具有分别为硬质碳薄膜的滑动部件之间形成的滑动面上设置含有羟基的润滑剂构成的,其中在边界下的滑动接触条件下表现出小于0.02的摩擦系数 在发动机油存在下在钢和钢之间的滑动面处表现出摩擦系数为0.1〜0.14的润滑。 每个硬碳薄膜由a-C或ta-C形成。 每个硬碳薄膜的硬度为1500-5000Hv,微维氏硬度为10克。 每个硬碳薄膜的膜厚度为0.3-2.0μm。 含有羟基的润滑剂是醇之一,是甘油。
