最近，甘油作为一种环保型润滑剂引起了研究人员的极大兴趣。当甘油与类金刚石碳涂层一起使用时，可以实现低摩擦，甚至超润滑。虽然TiN涂层目前被广泛用于改善成形工具、切削工具和机械元件的摩擦学性能，但没有关于甘油润滑下PVD TiN涂层摩擦学性能的文献。本文研究了TiN涂层与甘油的复合。结果表明，甘油在钢/TiN摩擦副中的润滑性能优于钢/钢摩擦副。提出了甘油在钢/TiN摩擦对中的作用机理。
Recently, glycerol has raised great interest among researchers as an environmentally-friendly lubricant. Low friction, even super-lubricity, can be achieved when glycerol is used with diamond-like carbon coatings. Though TiN coatings are currently widely used in improving the tribological performance of forming tools, cutting tools, and machine elements, no literature exists on the tribological performance of a PVD TiN coating under glycerol lubrication. This paper investigates the combination of TiN coatings with glycerol. The results show that glycerol exhibits excellent lubrication performance, which is stronger in the steel/TiN than in the steel/steel tribopair. The action mechanism of glycerol in steel/TiN tribopair is also proposed.
