...Asif Israr; Muhammad Zubair Khan; Ruqia Ikram; Yumna Qureshi; Kashif Riaz Wattoo Nowadays, mixing nanoparticles into cutting fluids is much more common to improve lubrication and cooling properties. Many studies have been carried out in the past to assess the machining performance using nanofluids...

...He Qiang; Guotao Li; Zhicai Du; Shuaiyang Ren; Zehua Xu; Yuan Xu The excellent tribological performance of nanoparticles as additives in lubricating greases has attracted widespread attention. In this study, a silane coupling agent (KH550) was used to chemically modify nanoscale mullite (composed...

...Khalida Akhtar; Saniya Yousafzai Calcium carbonate powder comprising uniform nanoparticles of novel morphology was synthesized under extensively optimized trial parameters. The as-prepared ultrafine rod shape CaCO 3 particles after characterizations were used as an antiwear/antifriction additive...

...Alexander D. Breki; Ekaterina S. Vasilyeva; Oleg V. Tolochko; Andrey L. Didenko; Michael Nosonovsky Frictional properties of a self-lubricating nanocomposite material with an A–OOO polyimide matrix reinforced by gas-phase synthesized tungsten diselenide (WSe 2 ) nanoparticles are studied...

...Chaoming Wang; Xinran Zhang; Wenbing Jia; Qiaoyuan Deng; Yongxiang Leng This study described the synthesis and the tribological properties of surface-modified Field’s alloy nanoparticles, which were prepared by a facile one-step nanoemulsion method and using ethyl carbamate as a surfactant...

.... Editor: Prof. C. Fred Higgs III. 15 08 2013 07 01 2014 Nanoparticles-laden gas film (NLGF) was formed by adding SiO 2 nanoparticles with volume fraction in the range of 0.014–0.330% and size of 30 nm into the air gas film in a thrust bearing. An effective viscosity of the gas-solid...

... of surface roughness parameters including the rms height, inter-island separation and a combined roughness parameter related to the pressure experienced by each nanowire. It was concluded that the rms height of asperity should not be lower than the radius of nanoparticles for effective lubrication...

... investigate the effects of crystal structures of workpiece materials on their tribological performance in conditions typical of pharmaceutical manufacturing processes. Sorbitol composites containing gold nanoparticles were evaluated for material properties and tribological performance. It was found...

... increased the viscosity slightly, while that of FU significantly reduced by the addition of the fullerene C 60 nanoparticles. The CE becomes thin with an increase in the shear rate, while the trend of thinning for FU is not as obvious as the former due to its much reduced viscosity...

... to the metal surface. Oils with nonpolar components, on the other hand, generate abrasive nanoparticles during rubbing. Experiments with margarine at elevated temperature resulted in the formation of a hard and thick tribofilm. An adsorption model is illustrated to highlight the effects of lubricant molecules...

.... It is shown that the 46 # turbine oil containing Mn 0.78 Zn 0.22 Fe 2 O 4 nanoparticles has much better friction reduction and antiwear abilities than the base oil. The 46 # turbine oil doped with 6 wt % Mn 0.78 Zn 0.22 Fe 2 O 4 nanoparticles show the best tribological properties among the tested oil samples...

...A. K. Pogosian; T. R. Martirosyan The development of new types of high-pressure plastic lubricants using natural minerals is of much importance. The effects of surfactant proportion and the structure of the nanoparticle thickener surface on the tribological properties of the bentonite-based grease...
