Mechanism of abrasion reduction in polydisperse system with carbon nanoparticles

The research is focused on the problem of abrasive wear. authors proposed a model based adsorption theory, where particles are used as transport nanoscale additive for lubricant. Laboratory tests have been performed to determine tribotechnical, physico-chemical and rheological properties polydisperse suspensions. It was determined that suspensions consisting lubricant carbon nanotubes high stability when pretreated by ultrasound. Rheological rotational viscometry indicated insertion slightly increases kinematic viscosity lubricants. Modification liquid lubricants with multi-walled results in wear reduction friction surfaces up 10%. combined use an contaminant efficiency 35%. Carbon provide shielding effect reduce cutting particles. analysis temperature dependences obtained tribological experiments allowed us conclude modification can increase thermal conductivity compositions, which contributes effective heat transfer from zone.
