Abstract

A large amount of research work has been conducted to evaluate and predict wear condition of components in machinery using wear debris analysis. However, there are few studies on quantitative surface characterization of wear particles although it has been recognized as an objective and effective means for assessing wear mechanisms and monitoring the condition of machinery. Moreover, for the surfaces of wear components that are difficult to access or analyze, it is possible to evaluate the quantitative surface information of the wear components through studying the surface characterization of corresponding wear particles. Therefore, it is imperative that the study of the quantitative surface morphology of the wear debris is conducted.

In this project, two most common motions occurring in machinery, that is, sliding and rolling, were simulated using a ball-on-disc tester. Wear particles were collected in running-in and steady-state wear stages and analysed using ferrography, a particle analyser, confocal laser scanning microscopy and computer image analysis techniques. Surface roughness parameters w;ere used to study the evolutions of the surface morphology of wear particles from running-in to steady state wear stages. Quantitative data on the evolutions of the surfaces of the wear debris were provided. The knowledge obtained in this research is important for predicting wear conditions using wear debris analysis techniques while further understanding of the wear mechanisms and wear characteristics has been also gained.
