Abstract

This study investigates the modification of TiO₂ ceramics by ECR microwave plasma treatment using Ar, O₂, and Ar-O₂ mixtures at different bias voltages. Wetting contact angle, optical, and microscopic measurements are performed to show the effects of UV irradiation with and without ion bombardment on the TiO₂ surface properties. Results show the occurence of nano-titania particles on the surfaces even at high-temperature sintering prior to plasma treatment. This contributes significantly to the biological and photocatalytic properties of the material.
