Effects on Micro-Surface Texturing of Mg/B4C Matrix Composites Under Dry Sliding Wear Condition

The predominant objective of this exploration is analyses of the wear conduct of pure Mg and Mg–B 4 C (5–15%) composites developed by powder metallurgy technique. The elemental map and microscopic examination of the composites were executed by energy dispersive spectroscopy (EDS) and scanning electron microscope (SEM) analysis. Wear conduct of the Mg–B 4 C composites was investigated at 2000 m sliding faraway with about 30, 60 and 90 N varying loads with and distinct sliding paces of 1, 1.5 and 2 m/s. The wear samples surfaces were explored by SEM, EDS and profilometer analysis. The outcomes establish that the Mg–15% B 4 C specimen has excellent wear behavior. The Mg–15% B 4 C composite has significantly minimum specific wear rate than that of Mg and Mg–(5–10%) B 4 C composites under all load conditions. The surface roughness of Mg decreases from 3.718 to 0.647 µm with increasing of B 4 C inclusion.
