Abstract

The influence of the parameters of the plasma-electrolytic oxidation process of WE43 magnesium alloy in a pyrophosphate electrolyte on the structure, composition, and protective properties of the formed coatings was studied using scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray phase analysis, and electrochemical methods. It has been shown that, with an increase in the duration of plasma electrolytic oxidation, the porosity of the formed coatings decreases and the content of magnesium orthophosphate in their composition increases. It was found that, compared to the original sample of WE43 alloy, PEO helps to reduce the corrosion rate in Hanks solution by 4.1–31.6 times.

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.
