Improvement in corrosion resistance of AZ91D Mg alloy in simulated body fluid by cerium-based/stearic acid composite coatings

Magnesium alloys have attracted attention due to their biocompatibility and biodegradability.In this work, composite coatings are developed to potentially improve the corrosion resistanceof AZ91D Mg alloy in simulated physiological fluid. Cerium-based/stearic acid coatings wereprepared by electrodep...
