摘要

摘要 本文研究了 ShKh-15 (ShKh) 钢球在有机液体和水中与石英玻璃 (QG) 和硼硅玻璃 (BG) 容器表面的无磨损摩擦。结果表明,无法准确预测哪种材料磨损得更快:硬的还是软的,钢球还是基体。耦合摩擦表面的磨损与工作体的总磨损之间的相关性最高(r ≈ 1)。在玻璃球组中,球的磨损频率(21 次测试中的 19 次)高于钢球组(9 次测试中的 5 次)。与 QG/ShKh 组(1 次)相比,BG/ShKh 组(5 次)更经常出现无磨损摩擦。仅含有一个端基 SiOH 的耦合表面不能提供无磨损边界摩擦。这项工作的实用性在于,ShKh/H2O 对无磨损摩擦的研究结果可以在轴承和大型人体关节的制造中得到实际应用。

Wear-Free Friction of Steel on Glass in Organic Liquids and Water

The paper considers wear-free friction of ShKh-15 (ShKh) steel balls on the surface of quartz glass (QG) and borosilicate glass (BG) vessels in organic liquids and water. It is shown that it is impossible to accurately predict which material will wear out faster: hard or soft, ball or substrate. The highest correlation between the wear of coupling friction surfaces is found for balls and the total wear of working bodies (r ≈ 1). In the group of glass balls, the balls wear out more often (19 out of 21 tests) than in the group of steel balls (5 out of 9 tests). Wearless friction is more often observed in coupled pairs BG/ShKh (5 cases) than in pairs QG/ShKh (1 case). Coupling surfaces containing only one terminal SiOH group do not provide wear-free boundary friction. The usefulness of the work is in the fact that the results of studies of wear-free friction obtained for the ShKh/H2O pair can find practical application in the creation of bearings and large human joints.

期刊介绍: Journal of Friction and Wear is intended to bring together researchers and practitioners working in tribology. It provides novel information on science, practice, and technology of lubrication, wear prevention, and friction control. Papers cover tribological problems of physics, chemistry, materials science, and mechanical engineering, discussing issues from a fundamental or technological point of view.
