IMPROVING THE ANTI-CORROSION PROPERTIES OF ENGINE OILS
Keywords:
anticorrosive additives, hydrophilic groups, hydrocarbon radical, protective properties, corrosive effect.Abstract
The purpose of this work is to study how to improve the anticorrosive properties of lubricants. With an increase in temperature, the combined action of oxygen, air and water present in the lubricating oil causes rusting of the crankshaft, the walls of the sleeves, the cylinders of the internal combustion engine.
We have studied anticorrosive additives as an additive to improve the anticorrosive properties of oils. dialkylphenyldithiophosphoric acid additive was used as such additives. The anticorrosive activity of these substances is associated with their ability to orient themselves on the oil-water surface so that hydrophilic groups bind firmly to water, and the hydrocarbon radical remains in the oil.
