Surface modification of magnesium alloys was performed using a coating process to optimize their performance. Friction stir processing for preparing magnesium-based high-entropy alloy coatings effectively addressed issues such as oxidation, pores, cracks, and poor coating quality found in existing processes. In addition, it substantially enhanced the hardness and wear resistance of magnesium alloys. The micro-structure and elemental distribution for the cross-section and surface for the magnesium-based high-entropy alloy coating had been studied. The impact of magnesium-based high-entropy alloy upon hardness and wear resistance of the magnesium alloy had been analyzed, focusing on its favorable forming and binding characteristics. Finally, the heat conduction process during friction stir processing were discussed in detail. The theoretical basis for the preparation of magnesium-based high entropy coatings was improved.
