RISGranular Flow Lubrication: Continuum Modeling of Shear Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Because at extreme temperatures, conventional liquid lubrication breaks down, researchers have proposed using flows of solid particles as a lubricating mechanism. The particles may be powders, ...
Characterization of Pelletized MoS2 Powder Particle Detachment Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A recently postulated concept of friction between solids states that the process exhibits elements of quasi-hydrodynamic lubrication in which the wear particles shed from one or both surfaces ...
Solution of Reynolds Equation in Polar Coordinates Applicable to Nonsymmetric Entrainment Velocities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reynolds equation in polar cylindrical (polar) coordinates is used for numerous tribological applications that feature thin fluid films in sliding contacts, such as chemical mechanical polishing ...
A Modeling Approach for Predicting the Abrasive Particle Motion During Chemical Mechanical Polishing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Chemical mechanical polishing (CMP) is a manufacturing process in which a wafer surface is polished by pressing it against a rotating pad that is flooded with slurry. The slurry itself is a ...
A Particle-Augmented Mixed Lubrication Modeling Approach to Predicting Chemical Mechanical Polishing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Chemical mechanical polishing (CMP) is a manufacturing process that is commonly used to planarize integrated circuits and other small-scale devices during fabrication. Although a number of models ...
A Lattice-Based Cellular Automata Modeling Approach for Granular Flow Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Liquid lubricants break down at extreme temperatures and promote stiction in micro-/nanoscale environments. Consequently, using flows of solid granular particles as a “dry” lubrication mechanism ...
The Inclusion of Friction in Lattice-Based Cellular Automata Modeling of Granular Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Granular flows continue to be a complex problem in nature and industrial sectors where solid particles exhibit solid, liquid, and gaseous behavior, in a manner which is often unpredictable ...
A Review of Dry Particulate Lubrication: Powder and Granular Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Research efforts related to dry particulates in sliding contacts are reviewed. In the tribology community, there are primarily two types of dry particulate lubricants that are studied—granular ...
A Pin-on-Disk Experimental Study on a Green Particulate-Fluid Lubricant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present investigation analyzes a green, petroleum-free lubricant that is produced by mixing two environmentally benign components—canola oil and boric acid powder. To study the influence of ...
Comparative Evaluation of MoS2 and WS2 as Powder Lubricants in High Speed, Multi-Pad Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As part of a program to develop solid/powder-lubricated journal bearings, a comparative evaluation has been performed to aid in determining whether MoS2 and WS2 powder are suitable lubricants ...
