Fabrication of Coatings on the Surface of Magnesium Alloy by Plasma Electrolytic Oxidation Using ZrO₂ and SiO₂ Nanoparticles

Figure 11

Dynamic load-unload dependence of changes in the depth of penetration of the indenter into the coating on the applied load: 1: coating formed in the base electrolyte, 2: coating containing ZrO₂ nanoparticles, and 3: coating containing SiO₂ nanoparticles.
