Abstract
The state diagram of the copper metaphosphate – molybdenum trioxide system, in which 2Cu(PO3)2∙4MoO3 compounds are formed, has been studied by the methods of physical and chemical analysis such as thermogravimetric, X-ray and IR-spectroscopic. The use of copper phosphoromolybdate additive to improve the physicochemical properties of greases used in friction units of railway equipment was studied. Tribotechnical tests of the created lubricants with a multifunctional additive 2Cu(PO3)2∙4MoO3 were carried out. The mechanism of the lubricating action of antiwear, extreme pressure, anticorrosion additives of copper phosphoromolybdate in model bases, which used LZ-TsNII greases, used in roller bearings of railway cars and TsIATIM-201, intended for friction units of automobile and aviation equipment, is considered.
