| Abstract: |
| 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. |
