Molecular dynamics simulation of a binary mixture lubricant for use in hard disk interfaces
In Hard Disk Drives (HDD), it is necessary to decrease the Flying Height (FH) between the head and the disk (currently, FH is around 3-5 nm) so as to increase recording densities. Retaining the solid lubricant has become a difficult proposition owing to intermittent contact between the surfaces. ZTMD and Z are used as solid lubricant to lubricate these interfaces. In this paper, the behavior of...

متن کاملMolecular Dynamics Simulation of Lubricant Adsorption and Thermal Depletion Instability
In this work, we incorporated a quartic bond potential into a coarse-grained bead-spring model to study lubricant adsorption on a solid surface as well as depletion instability. The surface tension density and the number density profiles were examined to verify the solid-liquid and liquid-vapor interfaces during heat treatment. It was found that both the liquid-vapor interfacial thickness and t...
متن کاملSolubility, Viscosity and Density of Refrigerant/Lubricant Mixtures
Solubility (vapor pressure) , viscosity and density have been experimentally determined for thirty-five potential refrigeration working fluids. Properties for low refrigerant concentration mixtures (0, 10, 20 and 30 weight percent refrigerant) were determined over the temperature range 0 to IOO•C (32 to 212"F) or to the critical temperature of the refrigerant, and pressure range 0 to 3,500 kPa ...
