The incorporation of B4C achieved an 85.7% increase in hardness, showcasing its effectiveness as a reinforcement material.
Adding SiC to B4C in hybrid composites resulted in a remarkable 101.2% hardness increase, demonstrating enhanced synergy in performance.
Wear resistance improved by 46% and 47% for B4C and B4C + SiC composites, respectively, underlining the impact of reinforcement ratios.
Microstructural analysis confirmed successful densification with relative densities between 92% and 97% and stable friction coefficients across samples.
