摘要: 利用四球机和环块试验机考察了一种水溶性硼酸酯在水中的摩擦学性能,并用X射线光电子能谱(XPS)和电子探针(EPMA)对摩擦表面进行了分析。摩擦学试验表明:水溶性硼酸酯在水中具有良好的润滑性能和承载能力。表面分析证明元素S,N和B在磨斑表面分布比较均匀,且B和S元素发生了摩擦化学反应。水溶性硼酸酯的抗磨作用机理是其在摩擦过程中发生了摩擦化学反应,生成了含硼酸、三氧化二硼、有机氮、二硫化亚铁、硫酸亚铁及摩擦聚合物等的复合膜,有效地提高了水基液的减摩抗磨性能。

Abstract: The tribological properties of water-soluble borate are evaluated using four-ball machine and HQ-1 block-on-ring tribotester. The rubbed surface is investigated using X-ray photoelectron spectroscopy and electronic probe analysis. The tribological test results show that the water-soluble borate has good lubricating performance and lad-carrying capacity. The surface analyses show that the content of element boron, nitrogen and sulphur in wear scar surface is well-distributed. The borate reacted with the metal surface in friction process and produced a complex film composed of organic nitrogen, boric aced, boron oxide, iron disulfide, ferrous sulfate and tribopolymer, which is effective on improving the antiwear, friction-reduction and load-carrying capacity of water-based fluid.

Key words: Antiwear mechanism, Borate, Tribological property
