摘要
锌合金作为一种重要的轻金属材料，广泛应用于航空航天、汽车制造、电子电器等领域。然而，锌合金在实际使用过程中易受腐蚀，严重影响其使用寿命和可靠性。为深入探究锌合金的腐蚀机理并提出有效的防腐措施，本研究采用电化学测试、表面分析和微观结构表征等手段，系统研究了不同环境条件下锌合金的腐蚀行为。通过对比分析纯锌与锌合金在模拟海水、酸性溶液及大气环境中的电化学特性，揭示了锌合金腐蚀的主要影响因素，包括氯离子侵蚀、氧化膜破坏以及微区电偶效应等。基于上述研究结果，提出了以钝化处理、涂层保护和合金成分优化为核心的综合防腐策略。研究表明，经过特殊工艺处理后的锌合金样品，在多种腐蚀介质中表现出显著增强的耐蚀性能，其中复合涂层技术可使锌合金的耐蚀寿命提高3倍以上。该研究不仅为锌合金的防腐设计提供了理论依据和技术支持，还为相关领域的材料选择和应用提供了重要参考，具有较高的学术价值和实际应用前景。

Abstract
Zinc alloy, as an important lightweight me tal material, is widely used in aerospace, automotive manufacturing, electronics, and electrical appliances. However, zinc alloy is susceptible to corrosion during practical applications, which seriously affects its service life and reliability. To thoroughly investigate the corrosion mechanism of zinc alloy and propose effective anti-corrosion measures, this study systematically examined the corrosion behavior of zinc alloy under different environmental conditions using electrochemical testing, surface analysis, and microstructure characterization. By comparing the electrochemical properties of pure zinc and zinc alloy in simulated seawater, acidic solutions, and atmospheric environments, the primary influencing factors of zinc alloy corrosion were revealed, including chloride ion attack, oxide film disruption, and localized galvanic effects. Based on these findings, a comprehensive anti-corrosion strategy centered on passivation treatment, coating protection, and alloy composition optimization was proposed. The research demonstrated that specially processed zinc alloy samples exhibited significantly enhanced corrosion resistance in various corrosive media, with composite coating technology extending the corrosion resistance lifespan of zinc alloy by more than three times. This study not only provides theoretical basis and technical support for the anti-corrosion design of zinc alloys but also offers significant reference for material selection and application in related fields, showcasing substantial academic value and practical application prospects.
