Abstract—

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 Т_cm 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 π_D with the experimentally obtained values of the corrosion rates of the steel surface in a corrosive environment under the films of sulfonate greases.

磺酸盐润滑脂在摩擦和腐蚀作用下润滑层破坏的研究

摘要-

研究磺酸盐润滑脂在边界润滑模式下固体摩擦过程中的润滑特性以及这些润滑剂在腐蚀环境中的防护性能。实现这些指标的一个共同要求是形成坚固的润滑层，保护零件表面免受破坏。对于所研究的每种含有各种增稠剂和分散介质的磺酸盐润滑脂，基于对 30-300°C 温度范围内摩擦系数的实验温度依赖性的分析，计算了边界层破坏的活化能值，并估计΢ _cm的值。研究表明，对于所检测的磺酸盐润滑脂，温度-能量准则πD的值与实验获得的磺酸盐润滑脂膜下腐蚀环境中钢表面腐蚀速率的值之间存在定性_相关性。
