| Abstract: | The microstructures of anodic films formed by different anodizing processes on magnesium alloy AZ91D and their protective performance were investigated by SEM(Scanning ELectron Microscopy) and salt spray test etc.The relevant protective performances included corrosion protection, abrasion resistance and the adhesion between anodic film and substrate. It was found that the mi-crostructure of different anodic films and their protective performance were different according to the processes remarkably. It was testified that the anodic film formed by the so called environmentally friendly new process could provide much effective protectiveness to the substrate. |
