FERROGRAPHIC EVALUATION OF PUMP CONTAMINANT WEAR 770769

REFERENCE: Tessmann, R. K., and G. E. Maroney, “Ferrographic Evaluation of Pump Contaminant Wear,” 1977 SAE National Off-Highway Vehicle Meeting, Milwaukee, Wisconsin, 12-15 September 1977.
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.
