Plasma electrolytic treatment of VT22 titanium alloy in electrolytes with carbon-containing compounds

Surface Engineering and Applied Electrochemistry, 2017
The study investigates the influence of electrolyte compositions containing acetone, glycerol, sucrose, ethylene glycol and ammonium chloride on the properties of VT22 titanium alloy in the process of the anode plasma electrolytic treatment (PET). An X-ray diffractometer and a scanning electron microscopy (SEM) were used to characterize the phase ...

Surface modification of SCM420 steel by plasma electrolytic treatment

Surface and Coatings Technology, 2013
Abstract Recently, much research has been carried out regarding techniques to improve the properties of steel surfaces, such as via ion-nitriding and gas nitriding. However, this needs a high vacuum rate or very expensive equipment and a long treatment time.

Fine structure of low-carbon steel after electrolytic plasma treatment

Materials Testing, 2021
Abstract This work shows the results of research of the fine and dislocation structure of the transition layer of 18CrNi3Mo low-carbon steel after the influence of electrolytic plasma. Conducted research has shown that the modified steel layer, as a result of carbonitriding, was multiphase.

Insights into plasma electrolytic oxidation treatment with particle addition

Corrosion Science, 2015
Abstract Plasma electrolytic oxidation (PEO) processing has received considerable attention for improving the corrosion or wear resistance of magnesium and its alloys. However, it cannot provide high-barrier long-term protection due to its high porosity.

Duplex surface treatments combining plasma electrolytic nitrocarburising and plasma-immersion ion-assisted deposition

Surface and Coatings Technology, 2001
This paper discusses the feasibility of improving the tribological performance of AISI 304 stainless steel by applying a duplex surface treatment which combines the methods of plasma electrolytic nitrocarburising (PEN/C) and plasma-immersion ion-assisted deposition (PIAD) of a diamond-like carbon (DLC) coating.

Characteristics of a plasma electrolytic nitrocarburising treatment for stainless steels

Surface and Coatings Technology, 2001
In this work, we investigate the feasibility of a plasma electrolytic nitrocarburising (PEN/C) treatment applied to AISI 316 stainless steel using a modified aqueous solution of urea as the treatment electrolyte. The substrate samples were connected cathodically to a high-current DC power supply and biased with a negative voltage in the range 220-260 V.
