Surface modification of metallic materials is the approach for developingfunctional properties to assure good biocompatibility, enhance tissue acceptance, and/ or inhibit corrosion rate. In this work, surface modification of two commercial magnesium alloys is presented. The alloys were coated with 58S glasscoating by sol-gel, with organic precursors such as silicon and phosphate alcoxydes and calcium lactate with the aim of inducing new bone formation by thebioactive glass together with the deceleration of the corrosion rate and hence the hydrogen evolution.
