This article describes the flexibility and the potentials of the most important finish for aluminium-based materials. After a suggestion for the classification of anodizing processes, the historical development of the electrolytic anodic oxidation (EAO) and the plasma-electrolytic anodic oxidation (PAO) are presented. In the following section the focus is given on selected topics concerning the process parameters, the microstructure including the layer composition and properties. The variability of the anodizing process parameters and the used materials provide this variety of application. Furthermore, both differences and similarities of the EAO and PAO processes are shown. The conclusion of this review emphasizes that there is still some need for further research especially in the interaction of the process, the formed microstructure and the resulted properties determining the final application. Hence new possibilities for this surface treatment will be open.

Ti6Al4V titanium alloy is widely used for industrial and medical applications. Several techniques of surface treatment are used to improve their mechanical, fatigue or corrosion properties like shot peening or anodic oxidation. The effect of these techniques combination on corrosion resistance of the base material was examined in this study. For this purpose, electrochemical impedance spectroscopy tests were performed in 0.1M NaCl solution. Shot peening was carried out using ceramic balls Z850 (Φ 850 μm) at the Almen intensity of 0.13 mmA. Anodic oxidation process was performed on ground and shot peened surface in 7% H2SO4 acid solution at constant used voltage of 65 V. Significant improvement of corrosion resistance by the surface treatment of Ti6Al4V alloy by shot peening with following anodic oxidation was observed however the improvement was lower when compared to surface treated only by anodic oxidation.
