XPS study of cerium conversion coating on the anodized 2024 aluminum alloy

Cerium-rich conversion coating was deposited on anodized aluminum alloy 2024 in a solution containing Ce(NO3)(3). X-ray photoelectron spectroscopy (XPS) was used as the analysis method. The composition of the Cc conversion coating deposited on the anodized 2024 alloy was investigated using this method. It was revealed that the coating predominately consisted of three-valent state cerium compound. Some of the CeIII was oxidized to CeIV in the outer layer coating. (C) 2003 Elsevier B.V.
