This paper aims to review recent progress and application of hybrid naofluid in machining process. The paper also discussed the preparation method of hybrid nanofluid and nano composite. Few aspects such as the stability of nano hybrid and characterization of hybrid nanofluid enlightened. The prior research on nanofluid shows that hybrid nanoparticle are work more effectively than single (mono) nanoparticle. The hybrid nanofluid are having higher thermal conductivity which affects significantly to machining output response variables.

“…On the contrary, the two-step method is utilised mainly in various industries for the synthesis of nanofluids [15]. Additionally, most of the researchers use this method during the preparation of nanofluids [30][31][32]. Choi and Eastman [4] especially suggested about two-step synthesis technique for oxide base nanoparticles rather than nanofluids based on metal particles.…”

This paper is presented to investigate experimentally on the stability of 40% ethylene glycol-based TiO2-Al2O3 hybrid nanofluids. Recently, the research is more highlighted on the thermophysical-properties of nanofluids. Hence, the stability of the hybrid nanofluids thoroughly assessed in this research work. The study uses the two-step method for preparing 40% ethylene glycol-based TiO2-Al2O3 hybrid nanofluids. The experiment is carried out for the various combination of mixture ratios including 20:80, 40:60, 50:50, 60:40 and 80:20 of TiO2-Al2O3 nanoparticles with a volume concentration of 0.1%. The stability assessment of hybrid nanofluids is accomplished through visualisation effect, transmission electronic microscopic observation, UV-Vis spectrophotometry and zeta potential value from particle size analyser. The findings show the optimum mixing ratios of TiO2-Al2O3 nanoparticles in terms of stability which is further confirmed by Zeta potential and absorbency from UV-Vis spectrophotometry. The results from the study reveal that 80:20 ratio of TiO2-Al2O3 nanoparticles possesses the best uniformity for over 21 days without any noticeable settlement of particles in the colloidal suspension. Moreover, 50:50 and 60:40 ratios show modest stability for almost two weeks while 20:80 and 40:60 ratios of TiO2-Al2O3 nanoparticles show minimum stability along with rapid sedimentation in the dispersion. However, it is also evident that the optimum mixing ratio of TiO2-Al2O3 hybrid nanofluids has excellent stability which will lead to further study on the thermal properties of nanofluids and finally motivate engineers to the real-life application of nanofluids.
