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.

The cyclic voltammograms (CVs) of polyacrylonitrile (PAN)-based carbon fibers (CFs) were measured in different electrolyte aqueous solutions, temperatures and concentrations. By analyzing the CVs, the mechanism of the anodic oxidation of PANbased CFs was investigated. The results show that the anodic oxidation of CFs is virtually the activated oxygen formed by oxygen evolution reaction of water reacts with the surface carbon of CFs. Although there are more activated oxygen formed in alkaline electrolytes, surface oxides of CFs are easier to be formed in acidic electrolytes. The higher temperature can make the oxygen evolution reaction of water and surface oxidation of CFs be easier and more violent. The variation in electrolyte concentration can affect intensity of the two reactions, whereas it does not affect the difficulty of the reactions.
