Abstract (english): In this study, a simple ball-on-prism test set-up is combined with an optical online wear particle detection system. The set-up is used to study the friction and wear characteristics of some exemplary oil lubricated metal-metal pairings. In addition to the time-resolved evolutions of the coefficient of friction and the volumetric wear, the number of wear particles, the particle sizes and the particle shapes are obtained during the test by using an online particle detection system. The number of small (<5 μm) wear particles increases steadily during the tests, while the number of larger (>10 μm) particles only increases during the running-in period and remains almost constant afterwards. Simultaneous drops in the curves for the coefficient of friction and the trend curves for the number of wear particles indicate a possible interrelation. The individual curves for the different particle sizes suggest that mainly small particles (<5 μm) contribute to that relation. © 2017 John Wiley & Sons, Ltd.
