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