摘要	This study investigated the microstructure and corrosion behavior of the cold-sprayed Zn11Al3Mg zinc alloy coating through analysis of phase composition, microstructures, and electrochemical behaviors. The results demonstrate that the CS-Zn11Al3Mg coating primarily consists of a finely structured ternary eutectic phase of Zn/Mg2Zn(11)/Al, with uniformly distributed submicron-sized Al phases. Additionally, a small amount of coarse Zn/Mg2Zn(11) eutectic phase coexisted with MgZn2 was also observed. The enhanced corrosion resistance of the coating was obtained when compared with cold sprayed Zn coating. The rapid sacrificial dissolution of Mg-Zn intermetallic compounds was observed in saline solution, leading to localized corrosion in the coating layer. Fortunately, the cooperative interaction of dissolved Mg2+ and Al3+ promotes the formation of protective corrosion products, namely Zn-5(OH)(8)Cl-2 center dot H2O and Zn/Mg-Al layered double hydroxides, provided long-term corrosion protection for mild steel.
