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.

Corrosion of amalgams under sliding wear
Dental Materials, 1996During mastication, dental amalgams are simultaneously subjected to corrosion by the oral environment and to a sliding-wear process by biting forces. In the present study, the effect of sliding wear on the corrosion behavior of two high-copper dental amalgams was investigated.An experimental apparatus was utilized that allows electrochemical testing ...

Determination of Archard’s wear coefficient and wear simulation of sliding bearings
Industrial Lubrication and Tribology, 2019Purpose This paper aims to present the methodology to determine Archard’s wear coefficient. By applying this coefficient into the numerical simulation of wear, it is possible to predict wear without long lasting and usually expensive experiments. Design/methodology/approach To determine necessary particles of Archard’s equation and calculate wear ...

Contact Drop and Wear or Sliding Contacts
Transactions of the American Institute of Electrical Engineers, 1937The results of a series of experiments, in which the processes of contact voltage drop and ring wear in sliding contact are demonstrated by means of a direct method, are presented in this paper. The results show that the wear of metalgraphite brushes and the rings upon which they operate can be reduced if they be operated in an oxygen-free gas instead ...

Ceramics International, 1996
The micromechanical and microchemical processes which take place during the friction of ceramics are not fully understood. The occurrence of surface plasticity and microfracture on a sub-grain size scale have been suggested but no clear experimental evidence has been provided.

Wear, 2001
The theory of elastic compliance as developed by Mindlin is used to discuss the sliding of one flat surface on another under dry, purely elastic conditions. A process is described by which a load may be supported across the interface, even during very easy, smooth relative motion and very low friction, provided the elastic materials are compressible.

The Challenges of Sliding Wear
World Tribology Congress III, Volume 1, 2005The production of nanocrystalline wear debris containing components from the worn specimen, from the counterface and from the environment does not support any of the better known wear models or wear equations based on adhesion, delamination, fatigue or oxidation.

Wear Mechanisms of Coated Sliding Surfaces
1993The wear mechanisms of coated sliding surfaces are discussed. A new approach to analyse wear mechanisms of coated surfaces is presented. It is based on a classification of the tribological contact process into macromechanical, micromechanical and tribochemical changes, and material transfer.

Mechanisms of the sliding wear of rubber
Wear, 1977Abstract The mechanism of the sliding wear of rubber was investigated using a hard sphere on a plane of filled rubber. Viscoelastic folds produced in front of the hard asperities of the rider enter the true area of contact and are abraded. It is suggested that the experimental method that was adopted could be used as a quick test to assess the ...

Observations on the Sliding Wear of Ceramics
A S L E Transactions, 1985Modern design concepts for heat engines with increased thermal efficiency call for the utilization of ceramic components. In some applications, lubrication of these components will be difficult to maintain. Consequently, a need exists for an expanded understanding of the dry sliding wear behavior of ceramics.
