The addition of Cr nanoparticles to a plasma electrolytic oxidation (PEO) electrolyte offers the possibility producing layers with broader range coating compositions and improved properties. In this study, effects various voltages on formation, microscopic morphology, phase composition were investigated in situ incorporation into PEO-coated Mg alloy. results show that corrosion performance was ...

This study looked into the influence of iron nitrate (Fe(NO3)3 on corrosion behavior a 6061 Al alloy treated by plasma electrolytic oxidation coating (PEO). PEO coatings were fabricated samples under AC conditions utilizing an alkaline-aluminate electrolyte containing 0 and 5 gr Fe(NO3)3. Surface examination demonstrated that some Fe2O3 particles effectively integrated layer produced in solutio...

The paper discusses a possibility of increasing the wear and corrosion resistance low carbon steel surface after cathodic plasma electrolytic boronitrocarburising in solution boric acid, glycerin, ammonium chloride, with subsequent anodic polishing an sulfate due to formation modified structure consisting dense oxide layer diffusion below it, which contains up 0.87% carbon, 0.80% nitrogen, boro...

A surface treatment process, composed of plasma electrolytic oxidation (PEO) and sealing by temporary oil preservation system containing corrosion inhibitors, was performed on AZ31 magnesium alloy in order to improve its resistance environments chlorides. Both atmospheric immersion conditions were evaluated electrochemical tests 0.1M NaCl solution together with salt spray test according STN EN ...
