Synergistic Effect of Graphite and Fly Ash on the Microstructural Evolution and Tribological Characteristics of Fe-Cu-Based Wind Turbine-Sintered Brake Pad Materials
The research focused on the effect of graphite proportion and the incorporation of fly ash in Fe-Cu-based friction materials produced via powder metallurgy technique. Microstructural investigation of the specimens demonstrated the homogenous distribution of the secondary element (Cu), lubricant (graphite), and reinforcements (fly ash) in the matrix (Fe). A maximum density of 5.7 g/cm3 was attained for the specimens, with an overall density of 70 pct of theoretical density. FM03 specimens showed a better wear resistance of 4.7 × 10−8 g/Nm with an optimum coefficient of friction of 0.4. The specific wear rate of the conventional friction material was 97.7 pct higher than the FM03 specimens.
