Showing papers in "Wear in 1958"

TL;DR: Abrasion patterns are found to increase the rate of abrasion; a distinction is therefore made between Intrinsic Abrasion, occurring in the absence of patterns, and Pattern ABrasion, and qualitative agreement with the experimental results is obtained.

TL;DR: The most satisfactory procedure for preparing titanium surfaces for severe service is by the application of metallic coatings, such as oxide, nitride, and carbide case hardening and coatings.

TL;DR: The extreme pressure lubricating properties of some sulphides and disulphides, blended in mineral oil, have been assessed by the Four-Ball Machine as discussed by the authors, and the mechanism of action of these compounds is discussed.

TL;DR: In this article, the elastic energy of an equiaxed fragment is compared to the surface energy at its point of attachment, such that smaller fragments remain adherent while larger fragments come off in loose form.

TL;DR: In this article, two versions of the blow-off method are described, by means of which the dependence of the viscosity of oils and other nonvolatile fluids on the distance from the solid wall can be measured, and localized with an accuracy of 10 A. The general conclusion is the impossibility of accounting for the phenomenon of boundary lubrication without taking into consideration the specific properties of the polymolecular boundary layers of liquids.

TL;DR: In this paper, a mathematical relationship connecting the length of grooves and the width of the wear-land on the clearance face with the value of maximum roughness on the surface generated was found.

TL;DR: In this paper, the analysis of the wear between metal surfaces is dependent on the distribution of the real area of contact, i.e., the mechanism of contact between two or more surfaces.

TL;DR: In this paper, the authors used crossed cylindrical specimens and by changing their orientations to the sliding direction, it is possible to vary this sliding distance over a wide range.

TL;DR: In this paper, the effect of neglecting inertia on the load capacity of hydrostatic thrust-bearings of the lubricant inertia is examined for both liquid and gaseous lubricants.

TL;DR: In this article, the authors studied the tangential forces and consequent movements between the rubber tire and rigid ground, and the frictional phenomenon involved and the resultant tyre-ground reaction.

TL;DR: In this paper, it was shown that indium work-hardens in the range of strains set up when a flat indium surface is indented by a 1 8 '' steel ball with loads up to 100 g.

TL;DR: In this paper, electrical contact resistance and coefficient of friction were measured for the purpose of investigating contact between metal surfaces subjected to repetitive reciprocating sliding, using a pendulum-type friction device.

TL;DR: In this article, the authors proposed a method to decrease contact wear, either by eliminating one of the causes of wear or by redesigning the contact mechanism, is of extreme importance in increasing the reliability of contacts.

TL;DR: In this article, the number and size of gaseous nuclei which exist in water and other liquids and give rise to cavitation and consequent erosion in hydraulic machinery are measured.

TL;DR: In this paper, a flat plate of metal 6 inches in diameter is rotated beneath a small tungsten carbide slider which carries loads up' to 4 kg and moves radially inwards.

TL;DR: In this article, the initial sliding friction of surfaces composed of a hard waxy grease has been found to be markedly dependent upon the length of time that the surfaces are loaded prior to sliding.

TL;DR: In this paper, a bearing theory is suggested, which takes into account heat phenomena in the film and the effect of temperature on viscosity, and an approximate method for the consistent solution of Reynolds' equation and the energy equation is developed.

TL;DR: The authors discusses the application of a lubricating process as described by Vitruvius about 25 B.C. He explains how there was a retrogression in machine-building from the decline and fall of the Roman Empire up till the Renaissance, when the work done by pre-Christian machine-builders became more generally known.

TL;DR: In this article, auteurs se sont efforces de presenter une methode experimentale permettant l'etude de the phenomene d'electro-erosion.
