Epoxy resin powder coating has been successfully applied on the corrosion protection of magnesium lithium alloys. However, poor wear resistance and microcracks formed during the solidification have limited it extensive application. There are limited approaches to exploit such anti-corrosion and mechanical properties of magnesium lithium alloys. Herein, the epoxy resin powder coating with polydopamine modified molybdenum disulfide (MoS₂@PDA-EP powder coating with 0, 0.1, 0.2, 0.5, 1.0 wt.% loading) was well prepared by melt extrusion to investigate its anticorrosion performance and wear resistance. The results revealed that the addition of MoS₂@PDA enhanced the adhesion strength between coatings and alloys, wear resistance and corrosion protection of the powder coatings. Among them, the optimum was obtained by 0.2 wt.% MoS₂@PDA-EP powder coating which could be attributed to well dispersion and efficient adhesion with coating matrix. To conclude, MoS₂@PDA-EP powder coating is meaningfully beneficial for the anticorrosive and wear performance improvement of magnesium lithium alloys.

环氧树脂粉末涂料已成功应用于镁锂合金的腐蚀防护。但其耐磨性​​差和凝固过程中形成的微裂纹限制了它的广泛应用。开发镁锂合金的这种抗腐蚀和机械性能的方法有限。在此，通过熔融挤出制备了聚多巴胺改性二硫化钼环氧树脂粉末涂料（MoS ₂ @PDA-EP 粉末涂料，负载量为 0、0.1、0.2、0.5、1.0 wt.%），以研究其防腐性能和耐磨性。 . 结果表明，添加 MoS ₂@PDA 增强了涂层和合金之间的粘合强度、粉末涂层的耐磨性和防腐性。其中，0.2 wt.% MoS ₂ @PDA-EP 粉末涂料获得了最佳效果，这归因于良好的分散性和与涂料基体的有效粘附。综上所述，MoS ₂ @PDA-EP 粉末涂层对镁锂合金的防腐和耐磨性能的改善具有重要意义。
