| Popis: | 97 This thesis uses anodization process on AA5083 Aluminum Alloy surface, use electroless containing Graphite powder(diameter 3μm)、Al2O3 powder(diameter 3μm)、Nano Al2O3 powder (diameter 20-30nm) additive with different concentration for plating on AA5083 Aluminum Alloy surface. Measure analysis surface morphologies, element compositions and surface roughness of the composite coatings before and after all tests are analyzed by scanning electron microscopy (SEM), X-ray energy dispersive analyzer (EDS) and surface roughness measurement. Experimental results indicated that electroless Cu/Nano Al2O3/Graphite composite coating exhibited the smoothes more dense and fine surface structure, consequently, giving the corrosion and highest hardness, wear-corrosion resistance in the 3.5%NaCl solution, and the anodizing treatment of AA5083 showed a beneficial effect to enhance these properties. |
