3. ZAM COATING TECHNOLOGY
Composition & Mechanism
Alloy Ratio : Zn-6%Al-3%Mg (Optimal for MgZn₂/Al-rich eutectic barrier) Protective Layer Formation : MgZn₂ Nano-Phases : Seal micro-cracks via hydroxide crystallization Al-rich Zones : Form stable Al₂O₃ layer against chlorides
Self-Repair : Mg ions migrate to exposed steel → create [Mg(OH)₂·MgCO₃] films
