Molybdenum disulfide coated aluminum alloys are of great interests in recent years due to their wide application in the space field. In this paper, a 350–400 nm-thick MoS₂ film with nano-flowers structure was produced on Porous anodic aluminum oxide (AAO)/Al substrate by magnetron sputtering. It is found that AAO aperture array on aluminum alloy could enhance the resistance of stress and deformation for aluminum matrix, and store the MoS₂ within the aperture during friction, resulting into prolonged lubrication time. Significant improvement in the lubrication performance (316.6 ×) at low friction coefficient (0.15) was realized compared with MoS₂/Al structure, and the wear rate decreased by ~98%. Our findings could provide new routes of surface modification for aluminum alloys in aerospace field.

近年来，由于二硫化钼涂覆的铝合金在太空领域的广泛应用，引起了人们的极大兴趣。在本文中，通过磁控溅射在多孔阳极氧化铝（AAO）/ Al衬底上制备了具有纳米花结构的350-400 nm厚的MoS ₂膜。研究发现，铝合金上的AAO孔阵列可以增强铝基体的抗应力和抗变形能力，并在摩擦过程中将MoS ₂储存在孔中，从而延长了润滑时间。与MoS ₂相比，在低摩擦系数（0.15）时的润滑性能（316.6×）显着提高/ Al结构，磨损率降低了约98％。我们的发现可以为航空航天领域的铝合金表面改性提供新的途径。
