摘要：

The paper describes the results of investigations performed on the lubricity of liquid crystals (LCs) and their solutions in petroleum and synthetic oils. LCs present in a lubricant were shown to lead to a decrease in friction and wear for solids. The LC concentration in lubricants was shown to affect the microrelief of the surfaces in frictional contact. The mechanism of LC-bearing surface interaction is discussed for the dynamic mode of contact.
