Determining the influence of carbon black in oil on the wear resistance of elements in the tribological system "steel – oil – bronze"

Establishing a pattern in the influence of two-layer greasing on the wear resistance of rails

“…The results of this work confirm the conclusions from earlier scientific studies [3,4,[15][16][17][18][28][29][30] on the positive use of lubricants with alloying additives in the friction pair «wheel-rail». However, it should be noted that the authors of papers [10,11,13,14] used plastic lubricants, and works [14,15,28,29] applied, as additives to oils, a variety of forms of carbon; the application of lubricants in the cited works did not involve an aerosol technique.…”

“…The expediency of using lubricants with alloying additives in the tribosystems, in particular wheel-rail, was addressed in a series of studies [10][11][12][13][14][15][16][17]. Thus, work [10] investigated the impact of ten different types of lubricants on the coefficient of traction, resistance, and wear under conditions of «complete lubrication» and «lubricant fasting».…”

“…The authors did not establish the wear rate dependences on the concentration of carbon nanoparticles. In [16], a rational concentration of carbon soot was found in an industrial oil, which is an alloying additive, which provided for minimal wear. However, the authors simulated the slip friction pair «steel -bronze».…”
