Özet
metallurgy and hot pressing to examine their microstructure, hardness and dry-sliding-wear performance. Powder compositions were verified with XRD and the microstructure of the sintered composites was evaluated using SEM (Scanning Electron Microscope) and EDS analyses. Hardness measurements and dry-sliding-wear tests were performed to evaluate the effect of reinforcement addition on the hardness and wear performance of the fabricated composites. Hot pressing of the composite with 50 w/% B4C required a significantly higher sintering pressure at the same sintering temperature. Increasing the B4C addition resulted in increased hardness values for all the composites, whereas the lowest worn volume and coefficient of friction were obtained with 10 w/% B4C.
