Transition of the lubricated wear of carbon steel

Wear, 1982
Abstract To study the transition of the lubricated wear of 0.53% C steel in the steady state, wear tests were carried out by rubbing the annular surfaces of two cylindrical test pieces in machine oil with no additives. The ratio of mating areas was varied to approach actual contact conditions. Three regions of variation in the coefficient of friction

The transition from the wear to the stress regime

Wear, 1996
Abstract This paper summarises the conclusions drawn from experiences gained on Spoornet with rail-wheel interaction. The reduction in wear between rail and wheel can result in the formation of higher contact stresses under worn conditions. A strategy is proposed combining design and maintenance practices on both vehicle and track to counter the so ...

Wear Transition Surfaces for Long-Term Wear Effects

1991
Tribologists tend to present friction and wear data as tabulations of values for specific ranges of test conditions. The conditions generally involve short test durations and express system loads in terms of applied forces. The designer, on the other hand, is concerned with stress levels and component durability, in particular time to failure.

Wear transition diagram for silicon nitride

Wear, 1993
Abstract Utilization of silicon nitride ceramics in applications involving contact between two sliding surfaces requires information on the effect of contact conditions and materials microstructure on tribological performance. In the present study, unlubricated wear tests were conducted on a hot isostatically-pressed silicon nitride under various ...

Quantitative wear maps as a visualization of wear mechanism transitions in ceramic materials

Wear, 1989
Abstract The materials properties of advanced structural ceramics are providing new technological opportunities for improved wear-resistant components in heat engines. Use of ceramics could result in higher efficiency, increased power output and longer lifetimes.

Modeling of microfracture-induced wear and wear transition in sliding of polycrystalline alumina ceramics

Wear, 1996
Abstract An equation has been proposed to describe sliding wear caused by microfracture in polycrystalline alumina ceramics. The wear equation has been simplified, and grain size dependence for dry sliding wear data by Wu et al. has been shown to agree with this equation.

The characterization of wear transitions in sliding wear process contaminated with silica and iron powder

Tribology International, 2005
Abstract When a machine is in operation, two moving surfaces interact to generate a large amount of wear particles. The wear debris generated inside the machine or contaminants from outside plays important roles in both two-body and three-body wear.

Wear transitions and tribochemical reactions in ceramics

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2002
Structural ceramics are used in diverse tribological applications due to their unique properties that include resistance to abrasion and erosion, resistance to corrosive wear, wear resistance at elevated temperatures, low density and unique electrical, thermal and magnetic properties.

A study on mild-to-severe wear transition due to inconformity of wear-induced shape

Wear, 2005
Abstract The mechanism of transition in wear-induced, time-dependent mild-to-severe wear was mainly discussed based on the calculation results of simulated wear. Convex-shaped sliding pairs generally accompany the rolling–sliding motion that causes some parts of the sliding surface to again come into contact with different areas of the mated surface ...

Wear of Ceramic-Transition Metal Composites

2002
Preliminary resultsand observation onthewear behavior on two ceramic-transition metal composites against two different slider materials are reported. The composites contained molybdenum or chromium as the metalphase, while 3Y-TZP and/or alumina comprised the ceramic phase.
