Evaluation of ball and disc wear scar data in the HFRR lubricity test
Lubrication Science, 2007AbstractThe high‐frequency reciprocating rig (HFRR) lubricity tester has become a widespread method for determining the lubricity of diesel fuels. The test is a ball‐on‐disc method, in which a steel ball scrapes over a steel disc immersed in the liquid to be tested. According to standards, the wear scar generated on the ball, in the form of the average

Wear, 1997
Abstract In a European research programme focused on the development and validation of test methods for thin hard coatings, friction and wear characteristics of TiN coatings were investigated. Ball-on-disc sliding tests were performed in ambient air of 50% RH at various applied loads under a fixed sliding speed.

An experimental study of ball-on-flat wear on a newly developed rotational tribometer
, 2011 With the objective of experimentally correlating several wear-process parameters, accurately and continuously over the duration of a sliding test, this paper presents a novel test rig as well as experimental results obtained by it. The developed test rig

Abstract For hot metal forming at high temperatures, lubricant is required to reduce friction and wear, as well as improve the product surface quality. Inorganic compound has been regarded as a candidate to replace the traditional oil/water lubricant for the forming process.

Biotribological response of CoCr alloy with added boron under ball-on-disc tests
Wear, 2013In the present study, the biotribological response of CoCr alloys modified with boron was investigated. Four CoCr alloy compositions with different boron additions were prepared using an induction furnace. A ball-on-disc tribometer with a friction coefficient measurement system was used to evaluate the wear behaviour. The wear factors under different

Characterisation and wear behaviour of SiC reinforced FeNiCrMo composite coating by HVOF process
Transactions of the IMF, 2023Analysis of the sliding wear and microstructural characteristics of iron based composite coatings are discussed. The feedstock, which consisted of 30% SiC and 70% FeNiCrMo, was mechanically combined using a ball milling process. A steel substrate made of

Wear Behaviors of Cp-Ti and UHMWPE Artificial Lumbar Disc Designed with Various Center of Radius
International Conference on Information Control Systems & Technologies, 2020The center of radius (CoR) of the lumbar spinal disc unit is usually thought to be below the center of the natural disc. The purpose of this research is to determine the appropriateness of CoR design toward wear rate, wear scars, and surface roughness of

Abstract The major oil supply for the ball-on-disc contact is provided by the lubricating oil reservoir and the oil ridges; however, the regularity of their changes has not been thoroughly investigated. In this study, the laser-induced fluorescence technique was adopted to determine the film distribution of the oil reservoir and the ...
