There are two types of friction modifiers (FMs) used as lubricant additives: Reaction film FMs (RF-FMs) and adsorption film FMs (AF-FMs). While RF-FMs provide good performance in severe conditions, AF-FMs excel in mild conditions. This empirical evid

Previous studies investigated the wear mechanisms under dry sliding conditions and in new oil. However, in practice, wear particles and dust are introduced into the lubricating oil of the machinery. Therefore, it is difficult to conclude that the wea
