Bio-medicinal application for plasma electrolytic oxidation of metals
Plasma electrolytic oxidation (PEO), a novel method for forming ceramic coatings on metals, has been researched extensively in recent times. By applying high voltage between dielectric thin films, a plasma micro-arc is induced through penetration of breakdown in film boiling layer. Such a method …

Phenomena Associated with Individual Discharges during Plasma Electrolytic Oxidation
… electrical breakdown (discharge) events during plasma electrolytic oxidation (PEO) of aluminium alloy substrates. Discharges were found to occur in extended sequences termed “cascades” at particular locations. This was a feature common to all the substrates and processing frequencies …

Investigation of Plasma Electrolytic Oxidation (PEO) Coated Bores in Internal Combustion Engines
… the feasibility of use for low-friction Plasma Electrolytic Oxidation (PEO) coatings on cylinder bores in order to reduce the frictional coefficients along the piston ring and cylinder bore sliding surface. For PEO coatings, wear is a limiting factor and this study aims at understanding …

Development of quantitative techniques for the study of discharge events during plasma electrolytic oxidation processes
Plasma electrolytic oxidation, or PEO, is a surface modification process for the production of ceramic oxide coatings upon substrates of metals such as aluminium, magnesium and titanium. Two methodologies for the quantitative study of electrical breakdown (discharge) events observed during plasma …

Nanoindentation Under Dynamic Conditions
… resistance of several novel coatings formed by plasma electrolytic oxidation (PEO) of Ti-6Al4-V. Multiple impact indentation results appear to subjectively rank the erosive wear performance of both ductile and brittle materials. Comparison of normalised performance of coating systems on …
