Аннотация:This study employed micro-arc oxidation (MAO) technology to modify magnesium alloy (MA) surfaces for enhancing bonding strength with carbon fiber reinforced polymer (CFRP). The MAO treatment created porous surface structures with improved hardness, roughness and wettability, and was combined with resin pre-coating (RPC) technology to facilitate high-viscosity epoxy infiltration into micro-pores. Using an MAO electrolyte system containing “20 g/L Na2SiO3 + 15 g/L KOH + 8 g/L KF” in conjunction with RPC modification achieved a bonding strength of 14.2 MPa, representing a 144.8% improvement over the baseline strength. The failure mode transitioned from MA interface debonding to predominant CFRP fiber tearing, demonstrating significant interfacial strength enhancement. This work exhibits MAO as an effective approach for improving MA-CFRP bonding strength, offering a promising strategy for industrial production of high-performance MA-CFRP composites.
