Effect of Multilayer and Gradient Structures on the Corrosion Resistance of (Zr,Hf,Al)N Coatings
Severe micro-galvanic corrosion in harsh marine environments greatly limits the corrosion resistance of high-strength aluminum alloys. To address this issue, this study employs a filtered cathodic vacuum arc deposition (FCVAD) system to deposit three Al-(Zr,Hf,Al)N composite coatings with different structures on the su...
