Modelling of Plowing and Shear Friction Coefficients During High-Temperature Ball-on-Disc Tests
Tribology International, 2009During high-temperature ball-on-disc tests of aluminium against steel, hot aluminium deforms and wear track evolves. The individual contributions of plowing and shearing to the apparent friction and the contact pressure are unknown. The aim of the research was to develop a model capable of determining these parameters.

Tribological performance of surface with different wettability under ball-on-disc test
Applied Surface Science, 2020Abstract This paper proposes an innovative and reliable method to reduce friction and wear using a robust lyophobic surface with microstructures. The tribological performance of four kinds of surfaces, including a microstructured surface (MS) without low surface energy treatment, a lyophobic microstructured surface (LMS), a robust lyophobic ...

On the Wear Measurement and Calculation in Ball on Disc Test
World Tribology Congress III, Volume 1, 2005The pin on disc test configuration is widely used in laboratory friction and wear testing of materials. The variant configuration ball on disc offer an advantage of the ball being self-aligned with respect to disc. Also, usage of ball allows for higher accuracy of wear measurement compared to ball weight loss evaluation.

The aim of this paper was to characterize different classes of materials, light metals, steels, cobalt–chromium-based and ceramic materials under tribological stress and to determine the reproducibility of the measurement results by monitoring the production, processing and analysis of the test materials.

Wear of water lubricated silicon nitride in ball on disc test
Tribology - Materials, Surfaces & Interfaces, 2010AbstractThe ball on disc test configuration is preferred to the flat ended pin on disc because the ball is self-aligned and measurement of wear on the ball is of higher accuracy, compared to the pin. Silicon nitride, sliding on itself in water, was tested with the ball on disc tribometer.

Wear performance of Fe-Cr-C-B hardfacing coatings: Dry sand/rubber wheel test and ball-on-disc test
International Journal of Refractory Metals and Hard Materials, 2018Abstract Minimizing wear would ensure reduced loss of material, labor and time for numerous branches of industry. Hardfacing coating method is a promising application to overcome this loss. The purpose of the the hardfacing application is to support, repair or improve the surface that is susceptible to abrasion by forming hard phases.

Abstract This paper investigates both experimentally and theoretically the effect of lubricant on the interface stresses under high temperature. A statistical formula was developed to predict the Stribeck curves by considering asperity-lubricant interactions at the contact interface.

Identification of wear process parameters in reciprocating ball-on-disc tests
Tribology International, 2011Wear test results are presented for a spherical indenter in reciprocal motion interacting with soft (aluminium alloy) and hard (construction steel) substrates. The aim of this paper is to provide evidence of the evolution of the contact zone, specification of wear scar depth and surface roughness in the contact zone.

Ball-on-disc tests were carried out at elevated temperatures to determine the friction behaviour of the 7475 aluminium alloy against steel, resembling the material mating during hot extrusion. Friction coefficient was found to increase markedly with rising temperature, suggesting that the commonly accepted assumption of an unvaried friction coefficient
