Title:

Improving the reliability of machinery tribosystems by modifying the contact surfaces with nanodispersed and polyfunctional additives

 

Abstract:

University experts (Kyiv), specialized in friction and wear in machinery, has developed a mathematical model for predicting the reliability of tribomechanical system under rolling with slippage unsteady conditions. It is based on regression equations that determine the dynamics of surface wear and kinetics of forming boundary layers. The scientists are interested in cooperation with companies manufacturing and improving lubricants.

 

The description of the proposal:

A mathematical model for determining the efficiency of lubrication depending on performance (load, speed, temperature) and structural (type of metal, oil fractional composition, the presence of additives) factors has been developed. It enables to determine optimal operating conditions of the tribomechanical system.

 

Innovative aspects and benefits:

According to the results of this study, it has been found that to expand the range of minimizing friction and wear processes it is necessary to increase energy designed to form stable boundary structures in tribotechnical contact. Thus, it has been found a mechanism for improving anti-friction properties of TAD-17i oil when using the special nanodispersed additive Fullerene C60 in motor and transmission oils under rolling with slippage and sliding unsteady conditions.

Additional information:

The mathematical model has been developed for determining the efficiency of lubrication to predict the durability of friction pairs with local contact shape on the basis of evaluation:

– antifriction and antiwear properties of oils according to the dynamics of change in microhardness, roughness and rheological properties of oils (unsteady conditions);

– the efficiency of lubrication and antifriction properties according to the change in rheological properties of oils when forming boundary adsorption layers (steady and unsteady conditions).
