Cryogenic friction behavior of PTFE based solid lubricant composites
Solid lubricants used in aerospace applications must provide low friction and a predictable operation life over an extreme range of temperatures, environments and contact conditions. PTFE and PTFE composites have shown favorable tribological performance as solid lubricants. This study evaluates the effect of temperature on the friction coefficient of neat PTFE, a PTFE/ PEEK composite and an exp...
متن کاملNoise influence on solid-liquid transition of ultrathin lubricant film
The melting of ultrathin lubricant film by friction between atomically flat surfaces is studied. The additive noises of the elastic shear stress and strain, and the temperature are introduced for building a phase diagram with the domains of sliding, stick-slip, and dry friction. It is shown that increase of the strain noise intensity causes the lubricant film melting even at low temperatures of...
متن کاملSolid friction in gel electrophoresis
We study the influence of solid frictional forces acting on polymer chains moving in a random environment. We show that the total reduction in the chain tension resulting from the small friction between a polymer and fixed entanglement points is a steep nonlinear function of the number of entanglements ~exponential for stretched chains!. Therefore, solid friction can drastically change the dyna...
متن کاملFriction Control in Thin-Film Lubrication
A novel method is proposed for controlling and reducing friction in thin-film boundary lubricated junctions, through coupling of small amplitude (of the order of 1 Å) directional mechanical oscillations of the confining boundaries to the molecular degrees of freedom of the sheared interfacial lubricating fluid. Extensive grandcanonical molecular dynamics simulations revealed the nature of dynam...
متن کاملA Simple Geometrical Model for Solid Friction
We present a simple model for the friction of two solid bodies moving against each other. In a self consistent way we can obtain the dependence of the macroscopic friction force as a function of the driving velocity, the normal force and the ruggedness of the surfaces in contact. Our results are discussed in the context of friction laws used in earthquake models. PACS numbers: 46.30.Pa 81.40.Pa...
