Abstract:
A method of evaluating the corrosion resistance of a coated metal substrate, the method including putting a liquid composition into contact with a corrosion protection coating present on the surface of a metal substrate, the liquid composition including water, a gelling agent, corrosion-catalyst ions, and a color pH indicator; gelling the liquid composition in order to form a corrosion-accelerator gel in contact with the coating; performing a corrosion test during which the gel that has formed is left in contact with the corrosion protection coating; and evaluating the corrosion resistance of the substrate coated by the corrosion protection coating by observing the color of the color pH indicator present in the gel after performing the corrosion test.
