摘      要：The need to combine various metals in light-weight constructions requires the development of coatings that prevent galvanic *** double hydroxides(LDHs)can be an example of such coatings,which were previously successfully obtained in situ on individual *** addition,the possibility of LDH growth(including LDH growth in the presence of chelating agents)on the surface of plasma electrolytic oxidation(PEO)-coated metals was previously *** PEO+LDH combination could improve both corrosion and mechanical characteristics of the *** possibility of LDHs formation in situ on the surface of PEO-coated friction stir welded(FSW)magnesium-aluminum materials(AZ31/AA5754 system was selected as a model one)was demonstrated in the presence of 1,3-diamino-2-hydroxypropane-N,N,N ,N -tetraacetic acid(DHPTA)as a chelating agent,which was selected based on analysis of respective metal-ligand compounds *** growth was achieved under ambient pressure without addition of carbonates in the *** effectiveness of the resulting coating is shown both for corrosion resistance and hardness.
