Kinetic approach applied to the study of tribological characteristics of sulfonate greases

It is shown that it is possible to evaluate the anti-wear properties of sulfonate greases using a temperature-kinetic method, in which the processing of experimental results allows us to obtain the values of the conditional activation energy of the process of destruction of the modified layer. A method has been developed for estimating the conditional activation energy of the wear process of the modified layer, which ensures the separation of contacting bodies during friction in the mode of boundary lubrication at high temperatures. For sulfonate greases obtained on various thickeners and dispersion media, the values of the activation energy of the process of destruction of modified layers were determined and the ratio between the activation energy value and the values of wear indicators according to GOST 9490-75 was established.
