FERROGRAPHIC EVALUATION OF PUMP CONTAMINANT WEAR

This paper presents the results of research conducted in contaminant wear of fluid power components. Most of this research and development effort has focused upon hydraulic pumps and pumping type mechanisms. Recently, work was initiated using Ferrographic analysis to correlate the wear debris generated during contaminant wear testing with the degradation in performance of hydraulic pumps. The paper demonstrates the correlation of generated wear debris with the performance degradation of such components.
