Abstract
This study compares the corrosion behavior and surface bioactivity of a Mg alloy (ZE41) and a novel FSP-fabricated ZE41/Ti–6Al–4V/SiC metal matrix composite after immersion in simulated body fluid. The field emission scanning electron microscopy micrograph of metal matrix composite (MMC) exhibits a refined grain structure with uniformly dispersed reinforcement particles, confirming successful integration of Ti, Al, V, Si, and C into the Mg matrix. While the base alloy exhibited severe localized corrosion with deep pits, the MMC showed significantly enhanced corrosion resistance, with degradation rates decreasing from 4.6 mm/year to 0.86 mm/year (81% reduction). Energy-dispersive spectroscopy confirmed that the dispersed reinforcements promoted passivation and reduced galvanic corrosion. The MMC also displayed superior surface distribution of Ca and P, indicating improved bioactivity.
