Anti-Corrosion Layered Coatings Based on Electrochemical Zinc–Nickel Alloy

The influence of coating structure on corrosion resistance of Zn–Ni coatings in the salt fog chamber was studied by methods of X-ray phase analysis and electron scanning metallography. It is shown that the change of conditions of deposition of coatings leads to a strong change in their morphology. It has been established that the change of coating deposition conditions leads to a change in the phase composition of the coatings. It has been established that the coatings with fine-crystalline morphology having Ni5Zn21 phase in their composition have greater corrosion resistance.
