TL;DR: In this article, the process of filmy wear debris generation in boundary lubrication was observed successively using scanning electron microscopy, and the wear type, which was controlled by the plastic flow of asperities and the generated filmy-wear debris, was named "flow wear".

TL;DR: In this article, the friction and wear behavior of short-fiber-reinforced composites were investigated using tribomechanical testing and microscopy, and the observed wear rate vs. normal load data were explained by means of a wear equation derived from the concepts of crack propagation and classical mechanics.

TL;DR: In this article, a thermodynamic model of contacting solids is built and an interfacial layer of wear products is included, where the interactions between the bodies and the layer are determined by the phenomenological parameters.

TL;DR: In this paper, the wear properties of a series of 0.5 wt.% B bainitic steels have been made under dry sliding conditions, and it was found that the wear rate is not a linear function of load.

TL;DR: In this paper, the effects of operating parameters on the threshold voltages and impedance response of non-insulated rolling element bearings under the influence of varying levels of electrical currents have been studied.

TL;DR: In this article, an examination of the friction and wear properties of carbon-fibre-reinforced poly(phenylene sulphide) sliding against steel without lubrication was made.

TL;DR: In this paper, the tangential force measurement is used to measure the influence of friction at the coating-indenter interface and surface roughness on the results obtained in the scratch test.

TL;DR: In this paper, the same progression of surface change was observed by microscopy, by hardness indentations and by the use of the stylus roughness tracer in fired engines.

TL;DR: In this article, a negative-ion-radical action mechanism of these compounds has been proposed to understand the chemical behavior of alcohols in sliding contacts, especially in the boundary lubrication of aluminium-steel surfaces.

TL;DR: In this paper, the influence of zinc dialkyl dithiophosphates, fatty acids and extreme pressure additives in lubricating oils on the friction of sintered α-alumina and silicon carbide is investigated.

TL;DR: In this article, the reciprocating diamond scratch test was used to evaluate the wear properties of amorphous nickel coatings against carbon steel under dry sliding contact, and no correlation was found between wear rate and hardness; this is primarily because of changes in the mechanism of wear effected by processing, counterface materials or sliding conditions.

TL;DR: In this paper, a laboratory test program to determine the rolling contact fatigue behavior of a 0.5 wt.% C steel under water-lubricated conditions is described.

TL;DR: In this article, the chemical nature, thickness and distribution of the films formed on the wear track have been determined by X-ray energy dispersive spectroscopy using a method for analysing films.

TL;DR: In this article, an investigation into the workhardening mechanism and the method of improving the work-hardening ability and the wear resistance of austenitic manganese steel, under non-severe impact-loading conditions, by means of transmission electron microscopy and X-ray diffraction has been conducted in this project.

TL;DR: In this paper, a detailed examination of the gauge face of a rail used in unlubricated curved track under well-documented conditions has been carried out using a combination of optical and scanning electron microscopy.

TL;DR: In this article, the influence of ultrasonic irradiation of the spark gap on electrical discharge machining debris was examined using scanning electron microscopy and it was shown that the influence was highly significant with markedly high spheroidicity, size, copper pickup and incidence of collisions.

TL;DR: In this paper, an experimental program is designed to monitor tool flank wear using low frequency noise spectra resulting from the rubbing action of the tool and workpiece and it was found that the tool overhang was the most significant parameter in the level of noise emitted.
