Spectroscopic characterization of plasma during electrolytic oxidation (PEO) of aluminium

Surface and Coatings Technology, 2011
Abstract We present results of an optical emission spectroscopic study of Plasma during Electrolytic Oxidation (PEO) of aluminium in citric acid and in sodium–tungstate water solutions. The line shape analysis of the first two hydrogen Balmer lines indicates presence of two PEO processes characterized by relatively low electron number densities Ne ...

Plasma electrolytic oxidation (PEO) treatment of zinc and its alloys: A review

Surfaces and Interfaces, 2020
Abstract Recently, few papers about plasma electrolytic oxidation (PEO) treatment on pure zinc, ZA27 and Zn-0.1 wt.% Mg alloys have been reported. The PEO procedure of pure zinc in electrolytes of KOH showed that the KOH amount and additives control the growth of a compact and dense oxide.

Effect of cathodic micro-discharges on oxide growth during plasma electrolytic oxidation (PEO)

Surface and Coatings Technology, 2015
Plasma electrolytic oxidation (PEO) of magnesium alloy is performed in NH4F and alkaline-silicate electrolytes within various waveforms of bipolar current pulses to investigate the role of the cathodic bias on both the growth mechanism of PEO layers and the behavior of micro-discharges.

Spectroscopic and real-time imaging investigation of tantalum plasma electrolytic oxidation (PEO)

Surface and Coatings Technology, 2011
Abstract We present the results of plasma electrolytic oxidation (PEO) of tantalum in 12-tungstosilicic acid at 70 mA/cm 2 . For the characterization real-time imaging and optical emission spectroscopy (OES) were used. It has been detected that relatively small microdischarges (cross-sectional area  2 ) are dominant throughout the PEO, while the ...

An investigation of ceramic coating growth mechanisms in plasma electrolytic oxidation (PEO) processing

Electrochimica Acta, 2013
Abstract To further our understanding of the plasma electrolytic oxidation (PEO) process, and to aid in the optimization of the process, it is important to identify the mechanisms of coating formation. In the present work, coatings up to 110 μm thick were produced on an AJ62 Mg-alloy substrate using the PEO process. Optical emission spectroscopy (OES)
