Abstract
In this work, a coating based on a copolymer of methacrylic acid with acrylamide and zinc compounds (ZnO nanoparticles, zinc nitrate, and hydroxide) was obtained, the properties of which were tested for anticorrosion protection of U8A steel. Using IR spectroscopy, it was shown that the functional groups of the copolymer form complex compounds with zinc ions and are bound to ZnO by weak intermolecular interactions. Based on the data from corrosion diagrams and electrochemical spectra, the optimal ratio of MAC : AA monomers was determined: 1 : 9 wt %, respectively. Testing of coatings in a mixture of nitric and hydrochloric acids and in an environment of saturated hydrochloric acid vapors demonstrated that all types of additives enhance corrosion protection.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
