摘要

摘要--研究磺酸盐润滑脂的特性,如在边界润滑模式下固体摩擦时的润滑性以及这些润滑剂在腐蚀环境中的保护特性。执行这些指标的一个共同要求是形成强大的润滑层,保护零件表面免受破坏。根据对 30-300°C 温度范围内摩擦系数的实验温度相关性分析,计算出了边界层破坏的活化能值,并估算出了Тcm 值。研究结果表明,对于所研究的磺酸盐润滑脂,温度-能量标准 πD 值与在磺酸盐润滑脂薄膜下腐蚀环境中钢表面腐蚀速率的实验值之间存在定性相关性。

Investigation of the Destruction of Lubricating Layers of Sulfonate Greases under Friction and Corrosion

To study such characteristics of sulfonate greases as the lubricity during friction of solids in the mode of boundary lubrication and the protective properties of these lubricants in corrosive environments. A common requirement for the implementation of these indicators is the formation of strong lubricating layers that protect the surfaces of parts from destruction. For each of the studied sulfonate greases with various thickeners and dispersion media, based on the analysis of experimental temperature dependences of the friction coefficients in the temperature range of 30–300°C, the values of the activation energies of the boundary layers destruction were calculated, and the values of Тcm were estimated. The conducted research has shown that for the examined sulfonate greases, there is a qualitative correlation between the values of temperature-energy criterion πD with the experimentally obtained values of the corrosion rates of the steel surface in a corrosive environment under the films of sulfonate greases.
