Plasma electrolytic oxidation of brass
Surface and Coatings Technology, 2020Abstract Plasma electrolytic oxidation (PEO) is first reported for the non-valve metal of brass. The surface morphology of the PEO-treated brass has been examined, indicating the formation of a porous layer similar to that of PEO of valve metals.

Plasma electrolytic oxidation of hafnium
International Journal of Refractory Metals and Hard Materials, 2017Abstract This paper presents the results of the investigation of plasma electrolytic oxidation (PEO) of hafnium. Atoms ionized during the PEO micro-discharging were identified using optical emission spectroscopy. The spectral line shape analysis of the hydrogen Balmer line H β indicated the presence of two types of micro-discharges characterized by ...

Niobium treated by Plasma Electrolytic Oxidation with calcium and phosphorus electrolytes
Journal of the Mechanical Behavior of Biomedical Materials, 2018Niobium plates were electrochemically treated by Plasma Electrolytic Oxidation (PEO) with electrolytes containing phosphorous and/or calcium. Three different electrolyte and experimental parameters were used forming three different surfaces. Film morphology, thickness, and chemical composition were analyzed by scanning electron microscopy (SEM), and ...

Plasma electrolytic oxidation of titanium and improvement in osseointegration
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2013AbstractReducing the osseointegration time for biomedical titanium implants in surgical patients is an important goal. However, a huge controversy exists over the effectiveness of osseointegration of the surface layer by plasma electrolytic oxidation (PEO), which is a widely favored surface modification for titanium‐based implants.

Plasma electrolytic oxidation of zircaloy-4 in a mixed alkaline electrolyte
Surface and Coatings Technology, 2021Abstract Characteristics of coating resulted from plasma electrolytic oxidation (PEO) of zircaloy-4 in an electrolyte containing phosphate, silicate, and hydroxide were investigated. The mixed electrolyte is proposed to reduce power consumption. PEO was conducted in a DC mode at a current density of 30, 50, and 70 mA/cm2.

Nanoparticle incorporation in plasma-electrolytic oxidation
Transactions of the IMF, 2016One remaining problem of thicker PEO based topcoats on light metal substrates is the enhanced porosity with increasing layer thickness. While modern deposition techniques such as pulsed anodisation counteract this phenomenon, a simple current signal based approach cannot completely eliminate this problem.
