One of the functions of the oil is to protect the surface of parts from corrosion. As a result of corrosion processes, the surface layer of parts is loosened and destroyed, which inevitably leads to their increased wear and a decrease in the overall service life of the engines.Corrosion becomes especially intense when the engine is operated or stored in hot, humid climates. In this case, oil plays a double role: on the one hand, it protects the surfaces of parts from the aggressive influence of the external environment; on the other hand, the oil itself is corrosive due to the presence of corrosive substances in it.In order to combat corrosion, special additives are added to the oils. Anti-corrosion additives are mainly polar substances that easily adsorb to metal surfaces.
