Summary: This study focused on obtaining PEO coatings on secondary cast Al-Si alloys and comparing the properties derived from the use of different aluminate-based electrolytes. The findings suggest that aluminate-based electrolytes can increase coating thickness and density, as well as improve surface hardness, wear resistance, and anti-corrosion behavior. In addition, the electrolyte containing K2TiF6 showed the highest protection against wear and corrosion for the treated Al-Si alloy.

Summary: The addition of Cr nanoparticles to the PEO electrolyte improves the properties and coating composition of the layers. By incorporating Cr nanoparticles into PEO-coated Mg alloy, the effects of nanoparticles and different voltages on coating formation, microscopic morphology, and phase composition were investigated. The results showed significant improvement in corrosion resistance when the final voltage was set to 460 V and the concentration of Cr nanoparticles was 1 g/L. The presence of oxidized Cr nanoparticles increased the growth rate of the coating and sealed its open pores, resulting in improved corrosion resistance.

Summary: The hybridization of organic compounds with inorganic layers has led to the discovery of novel organic-inorganic hybrid materials with unique properties, such as a high corrosion stability and balanced catalytic activity. The successful deposition of a functionalized coating with flower-flake structures on defective surfaces has been achieved through a layer-by-layer self-assembly process. The main reason for the performance of the coating is believed to be the formation of stable coordination complexes due to molecular orbital interactions.

Summary: Orthopaedic implants often use magnesium and its alloys, which have better mechanical compatibility with bone tissue but lower corrosion resistance. This study investigated the use of plasma electrolytic oxidation (PEO) to modify the surface of AZ31 magnesium alloy and examined the effects of different concentrations of hydroxyapatite (HA) nanoparticles on coating morphology and corrosion characteristics. The sample with 3 g/l HA showed the best anticorrosion performance with the smallest average pore size, thickest coating, and lowest corrosion current density.
