“…Regardless these established standard procedures for AA2024‐T3, according to ISO, and for D16 AM, following GOST 4784‐97, the further improvement of these alloys by decrease of their granular structure and intermetallic particle size still remains an object of intensive scientific efforts . Besides, since the primers form intermediated layers between the upper coatings and the metallic surface, their structure is a key factor for the resulting coating adhesion.…”

As a common practice, the metallic alloys are always protected by multilayer coating systems against environmental corrosive impact. The primer layers of these coating systems serve for improvement of the adhesion between the upper and finishing coating layers and the metallic substrate (cerium oxide primer (CeOP) layers). Furthermore, the structural and morphological features possessed by the coating primers strongly depend on the metallic surface roughness, and composition. In the present research work, cerium conversion coatings were electrodeposited on two different aircraft alloys, with identical chemical compositions (AA2024-T3, and D16 AM). The relation between the protective capabilities of the obtained layers and the structural features of the respective alloys was elucidated by electrochemical measurements, via linear voltammetry (LVA) and electrochemical impedance spectroscopy (EIS), combined with SEM/EDX observations.
