Abstract
The present work aimed to develop a methodology to classify and identify abrasive particles, based on the mechanisms and types of wear correlating their test conditions. The abrasive particles (debris) were obtained from samples obtained by block on ring lubricated sliding wear tests with ABNT 1045 steel textured specimens. The debris were extracted from the lubricating fluid by a vacuum filtration process. In order to characterize these particulates, ImageJ® software was used, which provides geometric characteristics such as area, perimeter, centroid, aspect ratio and Feret diameter, which are fundamental for their characterization. Understanding these parameters can help clarify the mechanisms of wear of sliding bearings, since the morphological characterization of the particles is of paramount importance for the understanding of the abrasive wear phenomenon.
