Abstract : Friction stir processing is applied to fabricate magnesium alloy AZ91D surface composite reinforced with nanophase Al2O3 particles. The refined microstructure in the developed surface composite is induced by nanophase Al2O3 particles and recovery–recrystallization phenomenon by friction stir processing. The results of electrochemical corrosion test and immersion corrosion test reveal that the corrosion rate of the developed surface composite decreased in simulated body fluids. The study originally reports that the homogeneous dispersion of nanophase Al2O3 particles and formation of an adherent layer of corrosion products (calcium hydroxyapatite and calcium-magnesium phosphate) in the developed surface composite decrease the corrosion rate. Besides, the formation of these corrosion products that mimic the bone matrix would support bone growth and promote integration of implant bone.
