Tribology of anodized Al surfaces from the view of their crystalline structure

What is it about?

Anodization of aluminium (Al) is a well-known process for the production of oxidized Al surfaces. In the present work, three different Al-oxide layers, produced with different electrochemical methods, were investigated in view of their layer morphology and tribological properties.

Why is it important?

The newly developed Al-oxide layer, which possesses the lowest surface roughness and a very uniform porosity, provided the longest lasting low friction phase under unlubricated sliding conditions.
