Particle reinforced open porous anodizing layers on AA5005

摘要

The present work deals with the target aimed design of anodic oxide films on AA5005 by modified phoshoric acid anodizing and reinforcement by subsequent impregnation with nanosized silicon dioxide by chemical nanotechnology. The authors show the influence of the anodizing time on the oxide layer thickness, the pore diameter and the morphology. It is revealed that silicon dioxide nanoparticles are successful incorporated into the open structure pores of the layer. The anodizing and the incorporation process were carried out wet on wet.
