Biological performance and tribocorrosion behavior of in-situ synthesized CuxO/TiO2 coatings

Gas-Phase Produced Cu@CuO Nanoparticles on Microarc Oxidized TiO2: Effect of Size on Antibacterial Efficiency and Osteoblast Viability

“…Two main mechanisms of microbial inhibition are metallic ion interaction and direct contact with the bacteria cell, as reported in the literature. 46 In general, antimicrobial activity of NPs enhances with a decrease in their size. 38,64−66 However, our results indicate that the antimicrobial activity of Cu@CuO NPs increased with increasing NP size.…”

“…The antimicrobial activity of Cu@CuO NPs on MAO surfaces is shown here to significantly improve with an increase of the Cu content. Two main mechanisms of microbial inhibition are metallic ion interaction and direct contact with the bacteria cell, as reported in the literature …”

“…44 In the literature, there are limited works on Cu/CuO/Cu 2 O NPs incorporated on a MAO surface prepared on a Ti6Al4V alloy through a one-step MAO process. 45−48 46 Liang et al examined in vitro long-term antibacterial ability of Cu-doped porous coatings 47 and the antifouling properties of MAO coatings containing Cu 2 O on Ti6Al4V 48 were probed by Zhao et al However, in those works, Cu/CuO/Cu 2 O NPs were integrated into the inner layer structure rather than on the outer surface of the MAO coating, which is possible using a one-step MAO process. Importantly, antibacterial NPs should be concentrated on the outer layer of the implant surface, since this is where microorganisms first make contact.…”

“…In the literature, there are limited works on Cu/CuO/Cu 2 O NPs incorporated on a MAO surface prepared on a Ti6Al4V alloy through a one-step MAO process. − Li et al investigated the formation mechanism of Cu-incorporated MAO coatings on Ti6Al4V alloys while He et al evaluated tribocorrosion behavior and biological performance of in situ-synthesized Cu x O/TiO 2 coatings .

Corrosion behavior of in‐situ synthesized ZnO‐containing coatings of AZ31B magnesium alloy by micro‐arc oxidation in simulated body fluids

“…[47] EDTA 4À combines with Zn 2 + to form a stable complex with multiple of [Zn-EDTA] 2À , see Eq. ( 7), [48] and under the action of electric field force [Zn-EDTA] 2À moves toward the anode, as shown in Figure 7. From the time-voltage curve, it can be seen that the micro-arc oxidation process mainly consists of the preanodic oxidation stage and the micro-arc oxidation stage, as shown in Figure 8.…”
