Measurement of Mechanical Properties of Thin Solid Films II: Friction and Wear

1992
The friction and wear performance of surfaces is critical to the functionality of industrial mechanisms, engines transmissions and all manner of process plants, especially with regard to their efficiency of operation and life cycle costs. Whilst typically dominated by mechanical properties, it is increasingly realised that surface chemistry also plays ...

Friction mechanisms and interfacial slip at fluid solid interfaces

Journal of Physics: Condensed Matter, 2002
We present series of experiments based on near field laser velocimetry, developed to characterize the friction mechanisms at fluid–solid interfaces. For polymers, entangled polymer melts are sheared against smooth solid surfaces, covered by surface attached polymer chains of the same chemical species, having a controlled surface density.

A dislocation mechanism of friction between a nanoprobe and solid surface

Technical Physics, 2002
A dislocation mechanism of friction between an atomic-force microscope (AFM) probe and an atomically smooth solid surface is put forward. In this mechanism, the contact region is represented by an edge dislocation. The triboacoustic emission measured with an AFM shows the dislocation nature of friction.

Friction and the Dynamic Mechanical and Thermal Properties of Polyurethane Elastomers. Solid Polyurethanes

Progress in Rubber and Plastics Technology, 1995
The results reported indicate that the properties of polyurethanes elastomers can be tailored to serve a wide variety of applications, for low temperature uses as well. The glass transition temperatures of the soft segments (T gs ) which control the low temperature ...

Constructing a new methodology for teaching internal friction of amorphous solids: models, experiments and simulations

European journal of physics
Internal friction is an important tool to understand the movement of atoms and molecules in solid materials. It is widely used to study the evolution of microstructures, significantly contributing to our understanding of the dynamic relaxation processes ...

Microscopic mechanisms for kinetic friction: Nearly frictionless sliding for small solids

Physical Review B, 1995
In previous work, the present author presented calculations in support of the contention that the long-time average rate of energy dissipation that occurs when two sufficiently small nonmetallic solid bodies slide in contact with each other in steady state is nearly zero.

Friction and the Dynamic Mechanical and Thermal Properties of Polyurethane Elastomers. 1. Solid Polyurethanes

Cellular Polymers, 1993
The results reported indicate that the properties of polyurethanes elastomers can be tailored to serve a wide variety of applications, for low temperature uses as well. The glass transition temperatures of the soft segments (Tgs) which control the low temperature properties of polyurethane elastomers, ranged from -79°C to -27°C (DSC onset values ...

Secondary structure formation and wear mechanisms for solid lubricant coatings under friction in vacuum

Wear, 1994
Abstract Complex studies of the state of solid lubricant coatings formulated with various lamellar materials made it possible to determine the physico-chemical and physico-mechanical processes responsible for the development of a protective secondary structure under friction and to define the conditions providing transition to a mild mode of wear in ...

Superslipperiness at Low Temperatures: Quantum Mechanical Aspects of Solid State Friction

Physical Review Letters, 1999
It has recently been shown that there is no static friction in a contact of atomically flat crystallinesolids provided the periods of their lattices are incommensurate and they are interacting weakly. Inthe present Letter, it is shown that, at low temperatures, the phonon contribution to the coefficient offriction can be very small also, by virtue of the
