Magnesium-based alloys are considered to be promising materials for the fabrication of temporary bone repair medical implants. The AZ31 magnesium-based (AZ31-Mg) alloy contains 3% aluminum and 1% zinc in its microstructure, which gives it mechanical strength corrosion resistance. Nonetheless, rate is high, can lead implant failure due rapid degradation, triggers release harmful metal ions. In present work, a passive layer was obtained on AZ31-Mg alloy, subsequently, cerium oxide (CeO2) coating deposited through chemical conversion treatment using 0.01 M CeO2 as precursor. Based X-ray photoelectron spectroscopy, calculated amount Ce(IV) Ce(III) AZ31-Mg(OH)2/CeO2 93.6% 6.4%, respectively. showed improved resistance compared with bare sample. vitro assessment MC3T3-E1 pre-osteoblast cell viability that biocompatible after incubation 24 72 h. results revealed confers greater electrochemical stability biocompatibility properties, mostly presence Ce4+
