The present investigation summarizes detailed experimental studies with standard lubricants of commercial quality known as Racer-4 of Hindustan Petroleum Corporation (India) dispersed with different mass concentrations of nanoparticles of Cu and TiO2. The test bench is fabricated with a four-stroke Hero-Honda motorbike hydraulically loaded at the rear wheel with proper instrumentation to record...

This study investigates the degradation of a commercially available gear lubricant and potential nano-additives to mitigate such degradation. Initially, we performed an experimental on chemical API GL-4 EP90 by mixing different concentrations aqueous hydrochloric acid (aqueous HCl) varying from 0.0005% v/v up 0.0025% v/v, while maintaining overall water content in oil below prescribed limits. T...

Three-component organic/inorganic hybrid films were fabricated by drop-casting the mixed dispersion of nanodispersed-poly(nickel 1,1,2,2-ethenetetrathiolate) (nano-PETT), polyimide (PI) and super growth carbon nanotubes (SG-CNTs) in N-methylpyrrolidone (NMP) at the designed ratio on a substrate. The dried nano-PETT/PI/SG-CNT hybrid films were prepared by the stepwise cleaning of NMP and methano...

Abstract Many novel icephobic coatings have been shown to exhibit low adhesion strength ice grown at null or velocity. Of these, few also by impacting high velocity supercooled water droplets. Even fewer of these over a range environmental conditions. Those that such behavior held back their susceptibility certain bands UV-exposure. Here, made from Silicone Nanofilament (SNF) networks on anodic...

Aluminum composites exhibit high resistance to wear and corrosion, possess strength, offer durability more such properties. In this study, Al7075, reinforced with nano size SiC - Gr was produced by a stir casting technique its microstructure mechanical behavior were evaluated. Reinforcements added in the range of 0 3 wt. %. The tensile compression strength developed hybrid Metal Matrix Composit...

Recently the applications of functionalized magnetic nano particles are increased in a linear fashion. This is due to the ease of synthesis and controlled growth of magnetic nano particles. In the present investigation gentamicin drug functionalized Fe3O4 nanoparticles were synthesized by co-precipitation method. Thus obtained nano hybrid was characterized by Fourier transform infrared (FTIR) s...

The efficacy of ionic liquids (ILs) as lubricant additives to a model base oil has been probed at the nanoscale and macroscale as a function of IL concentration using the same materials. Silica surfaces lubricated with mixtures of the IL trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate and hexadecane are probed using atomic force microscopy (AFM) (nanoscale) and ball-on-dis...

In this paper, nano-TiO2lubricating fluid was chosen as an advanced rolling lubricant to investigate its effect on the hot rolled surface and metallographic structure of SS41 steel strips. The tribological performances of nano-TiO2 lubricating fluid were measured by a four-ball tribotester. The hot rolling experiments under different lubrication conditions were carried out by a four-high rollin...
