Abstract:

ZnS具有密排六方层状结构，层间剪切力较小，是一种有效的固体润滑剂。本文中我们采用水热法在金属锌基底上一步合成ZnS薄膜，这里锌基底既作为锌源参与反应，同时又为ZnS的生长提供基片。利用X-射线衍射和扫描电子显微镜对ZnS薄膜的结构组分和表面形貌进行了表征，同时采用往复式滑动摩擦磨损试验机，考察了干摩擦条件下ZnS薄膜的摩擦学性能。研究结果发现，金属锌经水热处理后，在表面上生成的ZnS薄膜由直径在~0.5μm的ZnS微纳米颗粒组成。在干摩擦条件下，ZnS薄膜可显著降低金属锌的减摩耐磨特性，同时对基底起到了保护作用。
ZnS is an effective solid lubricant because its close-packed hexagonal layered structure and low interlayer shear force. In this paper, zinc sulfide films are directly fabricated on zinc substrate through a one-step hydrothermal method. Zinc is used as both zinc source involved in the hydro-thermal reaction and the support for zinc sulfide film. The structure and morphology of ZnS film on zinc substrate are characterized by X-ray diffraction and scanning electron microscopy. The friction properties of ZnS film in dry sliding were observed. The results showed that ZnS film is composed of micro/nano particles with 0.5 μm, providing effective friction-reducing for the zinc substrate under dry sliding contact.
