Wear and wear transition mechanisms of ceramics
Wear, 1996Abstract The combination of indentation, inclined-plane sliding, and wear tests provides useful and unique way to investigate ceramic wear and wear transition mechanisms. The experimental results show that wear mechanisms of ceramics are predominantly dependent on the tribological contact stresses.

A wide variety of conditions cause wear, with many mechanisms contributing to the damage caused. The solution of a particular problem requires precise identification of the nature of the problem: care must be exercised in applying general solutions to individual problems.

The mechanism of wear of polytetrafluoroethylene
Wear, 1973Abstract Experiments to study the effects of heat treatment, speed and temperature on the friction and wear properties of polytetrafluoroethylene (PTFE) have been carried out. The mechanism of wear is discussed on the basis of the results of these experiments and electron microscopy of the friction surfaces.

Mechanical Wear and Lubrication [PDF]
, 1962 Abstract : This report covers work involving some literature survey and preparation of a presentation for the 1962 Educational Series of the American Society for Metals. This presentation covers the nature of mechanical wear and its reduction by lubrication in moving assemblies.

Wear Mechanism Based on Wear Anisotropy
Tribology Transactions, 2000Self-mated dry sliding wear experiments were conducted on alumina using a pin-on-disc configuration. Worn alumina surface showed pits and projections in the size and shape of the grains. This paper shows that formation of these pits and projections are due to the wear anisotropy observed in single crystal alumina.

Wear Resistance and Wear Mechanisms in Polymer + Metal Composites [PDF]
Journal of Nanoscience and Nanotechnology, 2010 We have investigated composites containing metallic micro-size and nano-sized particles as the 10 wt% dispersed phase. Branched low density polyethylene (LDPE) was the matrix. Microsized metals were Al, Ag and Ni; nanosized metals were Al and Ag.

The Mechanism of Fretting Wear
Journal of Lubrication Technology, 1973An experimental study has been carried out of wear and energy dissipation of contacts vibrated at high frequencies. The amplitude, number of cycles, and degree of lubrication were varied. In addition, an analysis was carried out of quantitative fretting wear results described in the literature.

Micro-mechanisms of wear — wear modes
Wear, 1992Abstract Grooves are formed on a wear surface in sliding contact and even when the contacting surfaces are of the same material the wear on the contact interface results in free particles. The abrasive friction and the abrasive wear have been proven to be the representative type of friction and wear in general sliding of surfaces from such ...

The competing wear mechanisms and wear maps for steels
Wear, 1995Abstract The development of wear maps is connected to the definition of dominant wear mechanisms and transition regions for pairs rubbing under different wear conditions. The well-known wear maps allow us to reveal the dominant contact conditions (mechanical approach) or the wear mechanisms (structural approach).
