文摘

Coating damage and delamination after aging of electrodeposition layer was obtained.

Stone Chipping resistance of the coating was evaluated by electrochemical studies.

Number and nature of damages were evaluated by electrochemical technique.

New parameters were defined based on Bode results to evaluate chipping degree.
