EFFICIENCY OF NANOPARTICLE COOLING AND LUBRICATION SYSTEMS IN MECHANICAL PROCESSING OF METALS

Abstract

In this article we investigated the effectiveness of cooling and lubrication systems based on nano-hydroxide alloys in the process of friezing. The study was conducted on AISI 1045 steel and MQL systems using CuO, Al₂O₃ and ZnO nanoparticles were compared and analyzed. Results showed that by using nanoparticle coolants, surface slippage was improved by more than 60%, shear zone temperature decreased by 25–32%, and instrument peel reduced by about 50%. Notably, the 0.5% CuO nanofluide based on neem oil gave the most effective results. SEM and EDS analyses proved that nanoparticles can form a tribochemical layer and shield the metal surface. This approach is promising for production industries where high precision and thermal stability are required.
