The application potential of SiO2, TiO2 or Ag nanoparticles as fillers in machining process fluids
Original language description
Process fluids are important as they create the appropriate conditions for machine cutting by improvingheat transfer, whereby extending the life of the cutting tool and increasing the surface quality of theproduct. The use of nanoadditives in the form of nanoparticles is highly efficient due to their highchemical and biological activity. Nanoparticles dispersed in a volume of process fluid can easily penetratebetween friction surfaces and thereby greatly influence the elastohydrodynamic effect of the lubrication.In our experiment, the addition of nanoparticles has a positive effect on reducing the average of frictioncoefficient during the tribological process by 8.9% and reducing the variance of friction coefficient by20.4%, as they lead to faster stabilization resulting in a significant reduction in the depth of material beingremoved by up to 52.1%. In this paper, the antibacterial properties of process fluids with nanoparticles ofTiO2, SiO2 or Ag were also evaluated (respiratory rates and bacterial viability). The results indicated thatthe nanoparticles reduced bacterial respiratory rates and viability by up to 90.4%.
