摘　　要：以AZ91镁合金为对象,采用等离子喷涂技术在其表面喷涂铝、Al2O3和Al/Al2O3复合涂层,研究了涂层的微观形貌、物相组成和磨损性能。结果表明,复合涂层表面存在有Al和Al2O3颗粒,Al2O3颗粒数量相对较少,尺寸约为40～90μm。Al/Al2O3复合涂层具有最佳的耐磨损性能。The Al coating, Al2O3 coating and Al/Al2O3 recombination coating on AZ91 magnesium alloy were prepared by plasma spraying. And the microstructure, phase composition and wear resistance of the coatings were studied. The results show that Al and Al2O3 particles exist in the Al/Al2O3 recombination coating. The size of Al203 particles are about 40-90 μm The Al/Al2O3 recombination coating show the optimum wear resistance.
