The Porous Structure of Silicon-Containing Surface Layers Formed on Titanium by Plasma-Electrolytic Oxidation

摘要

Elemental and phase compositions, surface morphology, and parameters of the porous structure of oxide coatings formed on titanium by plasma-electrolytic oxidation in aqueous silicate electrolytes are determined. The coatings are studied with the use of the X-ray spectral method, X-ray phase analysis, electron microscopy, and the water-vapor adsorption method. The parameters of the porous structure of coatings are found to depend on the duration of formation of the coatings, composition of the electrolyte, and additional thermal treatment.
