Microstructural and Wear Investigations of the Mg/$ B_{4} $C Surface Composite Prepared Through Friction Stir Processing

Abstract Friction stir processing (FSP) is one of the potential fabrication methods that usually modify the microstructural and wear characteristics of the material in the form of surface composite, thus enhancing the surface characteristics, namely hardness and wear resistance. In the present study, $ B_{4} $C particles were reinforced in the as-cast magnesium alloy (Mg–4Al–3Zn–3Sn–3Pb) matrix surface using FSP to produce the surface composite. The subsequent investigation signified the role of $ B_{4} $C particles on the microstructural and wear attributes of the magnesium alloy. The microstructural features revealed very fine grain structure and homogeneous dispersion of $ B_{4} $C particles in the surface composite produced. The reinforcement of hard and brittle $ B_{4} $C improved the hardness and wear properties of as-cast magnesium alloy. The predominant wear mechanisms identified in as-cast specimens were adhesion and abrasion, which transformed to abrasion and delamination with the addition of $ B_{4} $C particles..
