Electrolyte-Plasma Modification of Surface of Ti-Based Alloy during Electrohydrodynamic Mode of Anodic Process

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.
