1.2.3.1 What Adhesion Accomplishes Very strong adhesion can help suppress corrosion by resisting the development ofcorrosion products, hydrogen evolution, or water build-up under the coating [32-35].In addition, by bonding to as many available active sites on the metal surface aspossible, the[r]

Because the amount of chromium in the debris was alsolow, the authors suggest that chromium has no pH dependency for leach-ing; instead it merely leaches until it is gone.

Electrochemical Impedance Spectroscopy is a powerful tool which was widely used in the last decades to characterize corrosion processes as well as protective performances of pre-treatments and organic coatings [15-28]. This electrochemical technique is not destructive and can consequently be[r]
