Özet
In the present study, the influence of mechanical alloying time on microstructure and wear behavior was investigated for Fe-Cu-C alloy produced with powder metallurgy method. Within the scope of the study, Fe, Cu and C powders were mechanical alloyed using various milling time (15, 30, 60, 90 and 120 min). After pressing (600 MPa) compacts were produced, the alloy powders were sintered for 1 h at 1150 degrees C in the atmosphere-controlled furnace. After sintering, the specimens were prepared for microstructure examinations and wear testing. Wear tests were done using pin-on-disc device under various loads (10-30 N), sliding distances (400-2000 m) and 1 ms(-1) constant sliding speed. Result of the study showed that powder size increased in Fe-Cu-C alloys up to 60 min mechanical alloying time. Maximum density and hardness values in Fe-Cu-C alloys were obtained in Fe-Cu-C alloy with 60 min mechanical alloying. In addition, the highest weight loss in wear tests was achieved in 120 min MA'ed specimen, while the lowest weight loss was achieved in 60 min MA'ed one. Graphic
