Abstract
In this study, composite coatings containing calcium carbonate (CC) and hydroxyapatite (HA) were fabricated on titanium substrate via a novel plasma electrolytic oxidation (PEO) process in particle suspensions. The approach involved synthesizing CC particles via a carbonation route, reacting them with a Na2HPO4 electrolyte, and performing PEO at a limiting voltage of 450 V in the resulting bath. The coatings prepared were similar to 25 mu m thick, porous oxide layers enriched with CC and HA, also containing rutile, anatase, perovskite, and brushite phases. As shown by corrosion tests, particle addition yielded an approximately 16-fold increase in charge transfer resistance and a corrosion potential shift of about 670 mV toward more noble values compared to bare titanium. Scratch testing revealed similar to 30 % higher adhesion and scratch resistance for CC and HA-based coatings. The surfaces were highly biocompatible, bacteriostatic, and hydrophilic, with an initial water contact angle of similar to 30 degrees, decreasing to similar to 10 degrees after 2 min. They exhibited a moderately negative surface zeta potential of -22 mV at pH 7 and demonstrated sustained calcium ion release, reaching similar to 21 mg L-1 under static conditions after 20 days and maintaining similar to 2.5 mg L-1 in PBS under dynamic conditions for 30 days. These results indicate that CC-HA particles significantly enhanced the PEO coatings' functional characteristics, making them promising candidates for next-generation biomedical implants with improved performance.
