Finite‐element modeling of dry sliding wear in metals
Engineering Computations, 2001This paper is concerned with the calibration and validation of a finite‐element model of dry sliding wear in metals. The model is formulated within a Lagrangian framework capable of accounting for large plastic deformations and history‐dependent material behavior.

Thermal and thermomechanical effects in dry sliding
Wear, 1984Developments in the study of interrelated thermal and mechanical phenomena in sliding systems are reviewed. The topics reviewed include mechanisms of frictional heating and the distribution of heat during sliding friction, the experimental measurement and analysis of surface and near-surface temperatures resulting from frictional heating, thermal ...

Dry Sliding Friction Experiments at Elevated Velocities
Strain, 2010Abstract: An enhancement of an existing tribometer device developed by Philippon et al. (2004, Wear257, 777–784) is presented in this work. This experimental device is made up of a dynamometer ring and a specific load sensor allowing to apply an apparent normal force on specimens and to measure frictional forces respectively.

Dry sliding wear of diamond materials
Wear, 1982Abstract In pin-on-disc tests, diamond composites, consisting of diamonds imbedded in a silicon matrix, were run against themselves in air at a sliding speed of 125 cm s −1 and for loads up to 3.6 kgf. In addition, a few experiments involving sintered diamond compacts rubbing against a rotating metal ring in a ring-and-block configuration were ...

Sliding on Clean (Dry) Surfaces
1998Around 1940 Bowden and Tabor presented a simple theory for the origin of the sliding friction for clean surfaces [6.1]. They assumed that the friction force is the force required to shear cold-welded junctions formed between the solids.

Estimation of Flash Temperatures in Dry Sliding
Proceedings of the Institution of Mechanical Engineers, Part C: Mechanical Engineering Science, 1984The paper develops expressions for the flash temperatures experienced by contacting surface asperities during dry sliding. The analysis is based on the heat transfer equations of the Jaeger—Archard theory but additional terms are introduced to allow for the effects of junction growth and cold work in plastic conjunctions.

The effects of sliding conditions on the dry friction of metals
Acta Metallurgica, 1989Abstract A survey of the variations of μ in the dry sliding of steel on steel over a wide range of sliding conditions is presented in the form of a friction-regime map. At slow sliding speeds (v 1 m/s), the initial surface condition is quickly replaced by one characteristic of the wear process, and the coefficient of friction becomes, increasingly,

Dry sliding wear behavior of magnesium alloys
Wear, 2008Abstract Dry sliding tests were performed on as-cast magnesium alloys Mg 97 Zn 1 Y 2 and AZ91 using a pin-on-disc configuration. Coefficients of friction and wear rates were measured within a load range of 20–380 and 20–240 N at a sliding velocity of 0.785 m/s. X-ray differactometer, scanning electron microscopy, tensile testing machine were used to

Dry sliding wear of austempered ductile iron
Materials Science and Technology, 1995AbstractA series of austempered ductile iron samples were prepared at austempering temperatures of 370, 340, 300, and 270°C. Their sliding dry wear behaviour was studied under applied loads of 110, 300, 500, and 800 N. The results obtained showed that the wear resistance is independent of austempering temperature with low applied loads, but shows a ...
