Synergistic Effect of Graphite and Fly Ash on the Microstructural Evolution and Tribological Characteristics of Fe-Cu-Based Wind Turbine-Sintered Brake Pad Materials

This study focuses on the 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 aims to improve the performance efficiency and reduce material costs by incorporating these additives. The introduction highlights the increasing importance of wind energy and the need for reliable braking systems in wind turbines. The materials and methods section details the experimental design, including the use of powder metallurgy processing techniques and the sintering process. The results and discussion section presents the microstructural analysis, density measurements, and tribological performance of the fabricated specimens. The study concludes that the FM03 specimen composition shows promising results with a density of 5.42 g/cm³, microhardness of 198.1 HV, and an optimal coefficient of friction of 0.4. The future scope suggests further research into the material's behavior under different thermal and stress conditions and practical manufacturing challenges.
