Hafnium dioxide (HfO2) has a wide bandgap and high dielectric constant. We prepared ceramic coatings on Ti6Al4V alloys via plasma electrolytic oxidation (PEO) in an electrolyte with HfO2 particles. The influence of the particles microstructure, phase composition, elemental distribution, corrosion resistance PEO was systematically investigated. results showed that addition increased voltage (fro...

Abstract Considering the increasing interest for Al alloys in packaging industry, where component lightweighting allows higher process efficiency, as well use of additively manufactured parts, which may not show a satisfactory tribological behaviour as-built condition, anodising by Electrochemical Oxidation (ECO) and Plasma Electrolytic (PEO) was applied to A357 (AlSi7Mg0.6) produced Laser Powd...
