Abstract

This study statistically analyzes the tribological properties of AA6061-10 wt. % B4C mono composite and AA6061-10 wt.% B4C-7.5 wt. % MoShybrid composite. The tribological behavior of the composites was studied at atmospheric conditions using a pin-on-disk tribo-tester. The tribological experiments were conducted as per the full factorial design (FFD) experimental scheme. The ANOVA analysis of the wear rate revealed that the three factors, A (MoSparticles addition), B (applied load), and D (sliding distance) presented the physical and statistical significance on the wear rate. The ANOVA analysis of the friction coefficient revealed that the factors B (applied load) and C (sliding speed) and interaction AB (interaction of MoSparticles addition and applied load) presented the physical and statistical significance on the friction coefficient. It is observed from the main effects plots of the wear rate and friction coefficient that the increase in the levels of factors B (applied load) and D (sliding distance) increased the wear rate and friction coefficient. However, the wear rate and friction coefficient decreased with the increase in the level of factor A (MoSparticles addition).
