Tribological and mechanical behaviour of Al 359 composites reinforced with B₄C_p, SiC_p and flyash

Abstract The current work examines how flyash reinforcement, SiC p , and B 4 C p affect the tribological and mechanical characteristics of composites made of aluminum 359. Stir casting was used to create composite samples of B 4 C p , SiC p and flyash reinforced Al 359. The composites’ hardness, tensile behavior, and wear behavior were examined and contrasted with a control sample. Due to the ceramic phase, the B 4 C p , SiC p particles, and flyash reinforced Al 359 matrix are harder than the base matrix. When B 4 C p , SiC p and flyash are added to the base matrix up to 20 wt.%, the coefficient of friction increases significantly. Wear examinations were carried out on specimens under a variety of stress situations, and then five different wear processes listed here (wear groove, abrasion, delamination, oxidation, and plastic deformation) were explored. The finding of the abrasion test show that B 4 C p , SiC p and flyash enhanced composites have improved wear resistance when compared to a control specimen.
