“…Valve materials are capable of electrochemically forming adhesive strong surface oxide layers with unipolar conductivity in the material-oxide-electrolyte system. Recently, plasma electrolytic modification (PEM) and microarc oxidation (MAO) are becoming increasingly popular for modifying the surface of valve materials [1,11,[27][28][29][30]. The PEM method gives possibilities to synthesize nanostructured ceramic-like layers on the surface that have high adhesion strength, good corrosion-protective ability and wear resistance.…”

Plasma Electrolytic Modification of Zirconium and Its Alloys: Brief Review

et al. 2023

The review focuses on the surface modification of Zr and its alloys, which is necessary to expand the applications of these kinds of materials. Data on the properties of pure zirconium and its alloys are presented. Since surface engineering and the operation of the above materials are in most cases associated with the formation of oxide coatings, information on the characteristics of ZrO2 is given. In addition, attention is paid to phasing in the zirconium–oxygen system. It is noted that the most effective method of surface engineering of Zr and its alloys is plasma electrolytic modification (PEM) technology. Specific examples and modes of modification are described, and the reached results are analyzed. The relevance, novelty and originality of the review are determined by the insufficient knowledge about a number of practical features concerning the formation of functional oxide coatings on Zr and some of its alloys by the technology of PEM. In particular, the information on the phase composition and possibilities of stabilization of the tetragonal and cubic modifications of ZrO2, the effects of the component composition of electrolyte solutions and electrolyte suspensions, and the specifics of the treatment of additive shaping and deformed materials are rather contradictory. This review aims to collect recent advances and provide insights into the trends in the modification of Zr and its alloys, promote the formulation of practical recommendations and assess the development prospects.

“…It is known that plasma electrolytic modification (PEM) entails a substantial increase in widely demanded materials performance indicators such as mechanical properties, corrosion resistance, tribological properties and thermophysical properties [11,[27][28][29][30]. This certainly is also applicable to zirconium materials.…”

“…These discharges affect by thermal, plasma chemical and hydrodynamic influences, and the surface layer of the treating parts is modified in a ceramic coating, strongly bound with the base. 2 In other works [12][13][14][15][16] the plasma-electrolytic oxidation is determined as electrochemical formation of oxide layers on valve metals and alloys under potentials of sparking or arcing, i.e. as a result of spark and arc discharges on the boundary between oxide film and electrolyte.…”

This article briefly reviews modern methods for oxidizing coating of valve metals (Al, Ti, Mg, etc.). These methods include microarc oxidation, plasma-electrolytic-arc oxidation, anodic -spark oxidation. Their common characteristics as well as differences between these methods and electrolyte-plasma processing by electrohydrodynamic mode of anodic process are described. The composition, microstructure and surface morphology of the coating formed on the surface of titanium alloys depending on the electrolyte-plasma processing parameters are investigated.
