Abstract:

The automobile industry's increasing need for lightweight, high-performance materials has brought attention to Al-Si-Cu die-cast alloys, which face significant challenges, including porosity-induced defects, galvanic corrosion, and environmental degradation. Traditional chromate-based coatings, while effective, are being phased out due to toxicity and regulatory restrictions under REACH and RoHS. This review evaluates cutting-edge bio-inspired and self-healing coatings as sustainable alternatives to enhance the durability and corrosion resistance of Aluminum alloys. Key innovations include micro/nanocontainer-based inhibitor release systems, LDHs (layered double hydroxides) for on-demand corrosion suppression, and superhydrophobic composites mimicking lotus-leaf topographies. We critically evaluate the performance of these coatings using electrochemical (EIS, SVET) and non-electrochemical (SEM, XRD) techniques, emphasizing their efficacy in mitigating micro-galvanic corrosion caused by the heterogeneous microstructure of aluminum. Challenges such as scalability, mechanical durability, and cost-effectiveness are discussed, alongside emerging trends like graphene-enhanced barriers and bio-based polymers (e.g., phosphorylated chitosan). By bridging material science with bio-inspired design, this review provides a roadmap for developing eco-friendly, high-performance coatings tailored to automotive applications, ensuring compliance with environmental regulations while extending component lifespan under harsh operating conditions.
