Nanotribology at high temperatures

چکیده
Recent molecular dynamics simulation results have increased conceptual understanding of the grazing and the ploughing friction at elevated temperatures, particularly near the substrate's melting point. In this commentary we address a major constraint concerning its experimental verification.

Bridging the gap between macro- and nanotribology: a quartz crystal microbalance study of tricresylphosphate uptake on metal and oxide surfaces.
We report a quartz crystal microbalance study of the nanodynamical properties of tricresylphosphate (TCP) reaction films formed on high purity Fe, Cr, Fe oxide, and Cr oxide surfaces at elevated temperatures. The data reveal trace levels of interfacial slippage, potentially in conjunction with viscoelastic effects, for reaction films characterized by very low macroscopic friction coefficients. ...
متن کاملNanotribology of a vapor-phase lubricant: A quartz crystal microbalance study of tricresylphosphate (TCP) uptake on iron and chromium
Adsorption measurements of tricresylphosphate (TCP) on high-purity iron and chromium surfaces have been performed in ultrahigh vacuum with a quartz crystal microbalance in conjunction with Auger electron spectroscopy, yielding values for gas uptake rates, molecular slippage, and tribofilm stress levels in the temperature range 25–400 C. At room temperature, TCP uptake is observed to be limited ...
متن کاملGlobal Nanotribology Research Output (1996–2010): A Scientometric Analysis
This study aims to assess the nanotribology research output at global level using scientometric tools. The SCOPUS database was used to retrieve records related to the nanotribology research for the period 1996-2010. Publications were counted on a fractional basis. The level of collaboration and its citation impact were examined. The performance of the most productive countries, institutes and m...
متن کاملStudy of Citation Networks in Tribology Research
CitNetExplorer has been used to study the citation networks among the scientific publications on tribology during the 15 years period from 1998-2012. Three data sets from Web of Science have been analyzed: (1) Core publications of tribology research, (2) publications on nanotribology and (3) publications of Bharat Bhushan (a top-contributor to nanotribology research). Based on this study, some ...
متن کاملThe Ballistic Behavior of High Strength, Low Alloy-100 Steel at Sub-zero Temperatures
The ballistic response of the high strength, low alloy (HSLA-100) steel at ambient and temperatures of -400°C, -800°C and -1960°C is investigated in this work. Lambert-jonas equation is used to fit the experimental results into a curve. The effect of quenching on ballistic behavior of HSLA-100 is also studied. The experiments are conducted on 3mm thick rectangular specimens impacted by blunt ti...
