The problems of estimating the corrosion resistance of novel multilayer metallic materials with an internal protector, where the principle of protector-assisted pitting protection is applied, are considered. An electron-microscopic method is used to experimentally substantiate the mechanism of corrosion damage of the material layers. Electrochemical and chemical methods are proposed for accelerated tests to determine the rate of corrosion damage. The electrochemical method can be used to reveal the rate-controlling step of the process, to calculate the mass corrosion index, and to substantiate the choice of a protector for a certain aggressive medium. The chemical method can quantitatively estimate the efficiency of an internal protector and can determine the relative corrosion resistance index of a multilayer material in comparison with the corresponding monometallic material.
