Abstract

Development of an inexpensive, effective, and technologically simple method to occur natural self-organization of oxide nanopores would become very important in light of the ever-increasing needing. The anodization process has recently attracted a wide extent of research attraction in nanotechnology. An anodizing process is considered as effective technique for fabrication of passive layer, and synthesis of nanoporous metals with new morphology enhanced mechanical and electrochemical performances. Modern fabrication techniques involved in an anodic production of nanoporous metal focus on the variation of exterior properties during the electrochemical process. Fabricating anodic nanoporous metals are constrained by the major parameters are listed. Also, this review discusses a brief generic approach for electrolytic coloring and previous investigations for electrolytic coloring as finishing anodized surface with special metal particles affords appropriate optical properties in the anodized surface of aluminum applicable for solar absorption application. Surface mechanical attrition treatment (SMAT) is a new alternative approach that can facilitate anodization; it is a type of plastic deformation technique, used prior the anodization to convert the metal from polycrystalline into nanocrystalline. The conversion results in grain size refinement and establishment of the high density of grain boundaries. A comparison between the resulting anodic metals subject and not subjected to SMAT will be displayed. The discoveries in this review open a new pathway in the anodic fabrication of nanoporous materials. By the integration of both SMAT and anodization, this setup will be a new perspective in the future developments of nanomaterials.
