Abstract

The rapid developments in nanotechnology has led to the emergence of a relatively new class of fluids called nanofluids, which could offer enhanced thermal conductivity and reducing the surface tension of the base fluid. Neat oil is traditionally and commonly used in many fields such as cutting, grinding and machining applications. Different nanoparticles exhibit various physicochemical properties (e.g., structure and shape), which can influence their lubricating properties. In this work, we have engineered colloidal suspensions of nano composite with an average size of 30 to 50 nm of functionalized graphene was covalently bonded to boron nitride by a microwave process, the nanocomposite was dispersed with base fluid concentration ranging from 0.1 to 0.01% , by ultrasonication method. To obtain a uniform distribution of the nanocomposite in the fluid matrix, with the purpose of filling the research gap in the literatures, this paper presents experimental data of thermal conductivity and viscosity properties of hybrid graphene based nanocomposite in the nano fluids for effective grinding applications. The FTIR spectroscopy further confirmed the presence of pyrophosphate and metal-oxygen bonding with O-H stretching and existence of nitride bonds in the composites which reveal the existence of boron group and carbon particles in the composite nano-fluid. Machining parameters are measured during grinding applications using nano composite fluid. It is observed that properties such as surface roughness, temperature stability, cylindrical and chips morphology, and cutting efficiency drastically improved with increased tool life exhibiting better machining performance compared to base fluid. The grinding chips morphology observed in the scanning electron microscope revealed less shearing with improved martial cutting. The results showed that the type of nano-composite and its concentration in base fluid play a significant role in reducing friction. Recent Publications: 1.
