Dry sliding wear of nanostructured Fe30Ni20Mn20Al30

Intermetallics, 2012
Abstract The wear of both as-cast and annealed nanostructured Fe30Ni20Mn20Al30, which consists of fine alternating B2 (ordered b.c.c.) and L21 (further ordering B2) phases, was studied using pin-on-disk tribotests in three different test environments, oxygen, air and argon. The counterface in all tests was yttria-stabilized zirconia.

Modelling sliding wear: From dry to wet environments

Wear, 2006
Corrosive species in various forms exist widely in the environment and can significantly affect wear behaviour of materials, usually accelerating wear. Under conditions where the environments are seemingly non-deleterious in terms of corrosivity, some species from the environment can still affect the tribological behaviour of materials.

Estimation of Flash Temperatures in Dry Sliding

Proceedings of the Institution of Mechanical Engineers, Part C: Mechanical Engineering Science, 1984
The 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.

Dry Sliding Friction Experiments at Elevated Velocities

Strain, 2010
Abstract:  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.

Thermal and thermomechanical effects in dry sliding

Wear, 1984
Developments 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 ...

Sliding on Clean (Dry) Surfaces

1998
Around 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.

The effects of stoichiometry on the dry sliding wear of FeAl

Intermetallics, 2013
The effects of alloy stoichiometry on the dry sliding wear behavior of B2-structured FeAl were investigated using four different FeAl alloys containing 40, 43, 48, and 50 at.% Al. Room temperature pin-on-disk tribotests were performed against an yttria-stabilized zirconia counterface in four different environments: air, oxygen, 4% hydrogen in nitrogen,

Dry sliding wear of diamond materials

Wear, 1982
Abstract 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 ...

Temperature Maps for Frictional Heating in Dry Sliding

Tribology Transactions, 1991
When contacting solids slide, work is done against friction. Almost all the frictional work appears as heat, generated at or very close to, the surface at which the two solids meet. The local increase in temperature influences both the friction and the rate of wear.
