Plasma Electrolytic Oxidation (PEO) was applied to extruded ZM21 Mg alloys improve their corrosion resistance in a chloride-containing environment. PEO carried out DC mode and voltage control fluoride-free electrolyte. Potentiodynamic polarization tests 3.5 wt.% NaCl aqueous solution neutral salt spray (NSS) were out. Microstructural profilometric characterization, as well NSS performed differe...

In the present work, plasma electrolytic oxidation (PEO) is creatively introduced as a novel method to fabricate multi-layered nanospheres. Titanium (Ti) was oxidized in phosphate-based electrolyte containing ZnO nanoparticles (NPs), which results formation of nanospheres on ceramic coating. The as-fabricated nanosphere amorphous with three-layered architecture. inner layer contains Zn, Ca and ...

Plasma electrolytic oxidation (PEO) was applied to functionalise the surface of AA2024 alloy. A potassium titanium-oxide oxalate dihydrate based aqueous electrolyte used, which allowed direct formation a TiO2 layer on aluminium alloy substrate. The effect PEO treatment time and additional presence anatase particles in solution its properties (corrosion, wear photocatalytic activity) were invest...

The work involved the development and on-engine testing of a new “thermo-swing” barrier coating for reduced wall heat transfer increased thermal efficiency in future diesel engines utilizing aluminium alloy pistons. Such swing coatings, low conductivity specific capacity, have recently been proposed to produce dynamic layer that rapidly changes temperature upper surface piston crown response ad...
