Abstract

This study investigated the effect of varying bioactive glass (BG) concentrations (8–14 g/L) on the structural, electrochemical, and adhesive properties of coatings deposited on Ti-6Al-7Nb substrates via electrophoretic deposition (EPD). The SEM and EDS analyses demonstrated that rising BG concentration from 8 g/L to 14 g/L enhanced the coating uniformity, reduced the porosity and enhanced the particle packing. The coating thickness increased from 41.1 µm to 57.3 µm. Zeta potential measurements showed increased suspension stability with higher BG content, reaching 18.47 mV at 14 g/L. Corrosion resistance is enhanced with BG content, with the 14 g/L coating reaching the lowest corrosion current density (5.19 × 10⁻⁸ A) and rate (4.509 × 10⁻⁴ mmpy). Adhesion tests rated the 14 g/L BG coating as 1B due to better interlocking.
