| 中文摘要: |
| 目的 采用两步法在铝合金表面制备MoS2/MAO耐磨减摩复合涂层，并考察其摩擦磨损行为特点。方法 通过微弧氧化(MAO)技术和原位水热法在7075铝合金表面构筑MoS2/MAO耐磨减摩复合涂层，通过扫描电子显微镜(SEM)、X射线衍射仪(XRD)和Raman光谱对膜层的微观形貌和组成进行表征。利用摩擦试验机测试试样的摩擦性能，并通过三维轮廓仪分析磨痕形貌。结果 MAO膜层主要由Al2O3构成，含有少量SiO2，表面为典型的多孔结构，存在大量微孔，粗糙度较大。MoS2/MAO耐磨减摩复合涂层中的MoS2颗粒较均匀地填充在MAO微孔中，并覆盖在凹陷内，使得表面平整光滑而致密。摩擦测试结果表明，MAO涂层能够提高基体的承载能力，但其摩擦因数较大，波动较大。MoS2膜层为MAO提供了良好的润滑改性作用，使其摩擦因数减小。结论 MoS2/MAO耐磨减摩复合涂层能够显著提高基体的摩擦磨损性能。在低载荷下，MAO硬质涂层起着很好的承载作用，MoS2颗粒层起着润滑减磨作用，使摩擦因数始终较低且平稳;在高载荷下，MAO层表面的微凸体在应力作用下破碎，硬质磨粒和MoS2颗粒分布在磨损面，部分被挤出磨痕区，导致摩擦因数不断增大。 |

| The work aims to fabricate MoS2/MAO wear-resistant and anti-friction composite coatings on Al alloy surface by two-step method, and investigate the friction and wear behavior characteristics. The first step was to prepare a MAO coating on the surface of 7075 Al alloy by micro-arc oxidation (MAO) technique. The second step was to construct the MoS2/MAO wear-resistant and anti-friction composite coating on MAO coating by in-situ hydrothermal synthesis method. The micro-structure and composition of the coatings were characterized by Scanning Electron Microscope (SEM), X-ray Diffraction Spectrometer (XRD) and Raman spectrum. The wear resistance was measured with friction tester, and the wear scars were analyzed with 3D surface profiler. |
