采用两种不同形貌的ZnO纳米粒子和ZnO晶须作为摩擦改性剂，改善聚氨酯（PU）复合涂层的摩擦学性能。在干摩擦条件下，采用环-块磨损试验研究了不同形貌纳米ZnO填充聚氨酯涂层的摩擦学性能，并利用扫描电镜（SEM）和光学显微镜（OM）分别对磨损表面和配对环表面形成的转移膜进行了研究。结果表明，在PU涂层中加入低含量的ZnO纳米粒子和ZnO晶须，可以提高PU涂层和ZnO晶须的减摩抗磨性能，填料在降低PU涂层摩擦系数和磨损率方面上级ZnO纳米粒子。磨损表面的研究表明，ZnO纳米粒子和ZnO晶须填料能够增强PU涂层转移膜与配对环表面的附着力，从而显著降低PU涂层的磨损率。
The two different morphologies of ZnO nanoparticles and ZnO whiskers were used as the friction modifiers to improve the tribological behavior of the polyurethane (PU) composite coating. The tribological behavior of the PU coatings filled with different morphologies nanometer ZnO was investigated using a ring-on-block wear tests under dry friction condition, and the worn surfaces and the transfer films formed on the surface of counterpart ring were, respectively, studied by scan electric microscope (SEM) and optical microscope (OM). It was found that the addition of the low inclusion of ZnO nanoparticles and ZnO whiskers can improve the reducing-friction and anti-wear abilities of the PU coatings and ZnO whiskers, as the filler was superior to ZnO nanoparticles in terms of the ability to decrease friction coefficient and wear rate of the PU coating. The investigations of the worn surfaces showed that the fillers of ZnO nanoparticles and ZnO whiskers were able to enhance the adhesion of the transfer films of the PU coating to the surface of counterpart ring, so they significantly reduced the wear rate of the PU coating.
