Magnesium and its alloys are ideal for biodegradable implants due to their\nbiocompatibility and their low-stress shielding. However, they can corrode too\nrapidly in the biological environment. The objective of this research was to\ndevelop heat treatments to slow the corrosion of high purified magnesium and\nAZ31 alloy in simulated body fluid at 37\degC. Heat treatments were performed\nat different temperatures and times. Hydrogen evolution, weight loss, PDP, and\nEIS methods were used to measure the corrosion rates. Results show that heat\ntreating can increase the corrosion resistance of HP-Mg by 2x and AZ31 by 10x.\n
