Microstructural and electrochemical evaluation of Cu-TiO2 composite coatings fabricated by cold spray, HVOF, and flame spray

Key Points

• Cu-TiO2 composite coatings show enhanced electrochemical performance compared to traditional coatings.
• Cold spray method yielded higher microstructural integrity than flame spray and HVOF techniques.
• Evaluation of properties focused on microstructure and electrochemical responses in distinct fabrication processes.
• Findings highlight the potential of Cu-TiO2 coatings for industrial applications, requiring further exploration.
