Magnesium-based surface composites, enhanced via friction stir processing (FSP), are advanced materials offering superior surface properties. FSP effectively refines the microstructure, improving microhardness, strength, wear, and corrosion resistance while preserving the lightweight Mg matrix core. This review details FSP's role in developing these composites, emphasizing process parameters and reinforcement strategies. A key focus is on biodegradable biomedical implants, where such composites eliminate secondary removal surgery. Multi-pass FSP and hybrid reinforcements enable ultrafine-grained, homogenous structures. Optimizing tool speed and travel is critical for balancing mechanical performance with exceptional tribological and corrosion properties.
