Dry sliding wear of Cu–Be alloys
Wear, 2005Abstract The tribological behaviour of two Cu–Be alloys was investigated under dry sliding conditions against an AISI M2 steel counterface. The first alloy, Cu–Be1, was characterized by a hardness of 390 HV and a thermal conductivity of 106 W/mK, whereas the second one, Cu–Be2, had a lower hardness, 270 HV, and a higher thermal conductivity, 208 W/mK.

The bearing and seals operate often in the conditions of sliding wear. The present paper is an overview, concerning various aspects of cermet-metal dry sliding. The sliding wear is more of a surface phenomenon than abrasion, making it difficult to predict the wear from bulk properties.

On the correlation between wear and entropy in dry sliding contact [PDF]
Wear, 2011 Irreversible thermodynamic theory is employed to study the rate of wear as a degradation process in a dry sliding system. It is shown that the wear rate is linearly related to the entropy flow rate.

Dry sliding wear of nanostructured Fe30Ni20Mn20Al30
Intermetallics, 2012Abstract 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.

Dry sliding wear behaviour of bamboo
Wear, 1998Abstract Dry sliding wear behaviour of bamboo ( Phyllostachys pubescens ) against a grey iron (HT200) was examined on a block-on-ring machine. The wear volume of bamboo was a function of the normal load, the sliding velocity and the relative orientation of bamboo fibres with respect to the rubbing surface.

Dry Sliding of Nitrided NiTiHf
Tribology Transactions, 2019AbstractThe unlubricated friction and wear properties of the superelastic material NiTiHf, treated by either gas nitriding or plasma nitriding, have been investigated. Pin-on-disk testing of the studied materials was performed at sliding speeds from 0.01 to 1 m/s at normal loads of 1, 5, or 10 N.

Sliding mode compensation of dry friction
Proceeding of the 1996 IEEE International Conference on Control Applications IEEE International Conference on Control Applications held together with IEEE International Symposium on Intelligent Control IEEE International Symposium on Computer-Aided Contro, 2002This paper presents a sliding mode position controller for ultra-precision machining. Simulation results show the effectiveness of both continuous and discrete time sliding mode controllers. The friction model is Coulomb friction with a stick-slip effect and it is accurately simulated using a state event handler. The results suggest that this technique

The role of triboparticulates in dry sliding wear
Tribology International, 1998In this paper, wear processes and mechanisms for wear transitions with sliding time and temperature during sliding of a nickel-based alloy, N80A, in oxygen at temperatures to 250°C are discussed. Transitions in wear from high rates to low rates with sliding time were always observed at all the temperatures investigated.

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.
