...Ankit Saxena; Deepak Kumar; Naresh Tandon The present study explores the performance of novel vegetable oil–based greases containing nano-CaCO 3 as an additive. A series of greases with varying nanoparticle concentrations (0–4% w/w) are evaluated on a four-ball tester machine under a standard...

...Dongya Zhang; Zhongwei Li; Feng Gao; Xian Wei; Yuquan Ni In this study, composite coatings of polyvinylidene fluoride (PVDF) and epoxy resin deposited with La 2 O 3 and MoS 2 nanoparticles on the surface of a Babbitt alloy have been studied in order to improve its tribological performance. A pin...

...: George K. Nikas. 14 03 2014 26 05 2014 Nanoparticle additives increase the viscosity of lubricants, thus being an interesting solution for improving the load carrying capacity of hydrodynamic bearings. But, nanoparticles also change the thermal properties of the lubricant. Would...

... 16 04 2013 Although nanoparticle additives have been the topic of multiple studies recently, very little work has attempted to explicitly model the third body contact of nanoparticles. This work presents and uses a novel methodology to model nanoparticles in contact between rough surfaces...

...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...
