XPS Rust Layer Analysis for Steel and Al/Ti Coated Steel Exposed to Urban Atmosphere


Lila Meziane*, Mohamed loucif Seiad and Boualem Demri

Atmospheric corrosion is controlled by complex electrochemical and physical reactions occurring on metallic surface. Aluminum (Al) and Titanium (Ti) were used
for atmospheric corrosion resistance purpose. It is achieved through thin metallic layer coated on steel samples during one-year exposure. The composition and
structure of products formed and developed on steel and Al/Ti coated on steel surface during exposure period have been investigated by using X-ray Photoelectron
Spectroscopy (XPS). The results obtained showed the structure of lepidocrocite in the rust layer of steel and Ti coated steel. However, for the Al coated steel
sample, the structure found was goethite.
