Among the existing series of softer metals, magnesium (Mg) has attracted much attention due to its impressive strength-to-weight ratio. However, due to its ease of deformability, Mg tends to suffer from rapid degradation in a wide variety of abrasive and electrochemical environments. One method of improving its surface properties is through surface modification techniques. Among the existing techniques, laser shock peening (LSP) has been one of the most widely utilized processes due to its surface-hardening-like effects. Despite this understanding, a comprehensive review has yet to exist that encapsulates the strengthening mechanism of LSP for Mg and its influence in degradation environments. This review aims to encapsulate the existing research around the LSP field for Mg. Specifically, an understanding of the surface-strengthening effects in relation to its mechanical, tribological, corrosion, and tribo-corrosion characteristics is elucidated. Additionally, the feasibility of LSP for Mg materials in critical industries is also discussed. Through this work, a novel understanding of LSP for Mg can be understood, which can provide a future direction for research in this field.

在现有的一系列较软金属中，镁（Mg）因其令人印象深刻的强度重量比而备受关注。然而，由于镁易于变形，因此在各种磨料和电化学环境中往往会快速降解。改善其表面性能的一种方法是通过表面改性技术。在现有技术中，激光冲击强化（LSP）由于其类似表面硬化的效果而成为最广泛使用的工艺之一。尽管有这样的认识，但还没有一个全面的综述来概括 LSP 对 Mg 的强化机制及其在降解环境中的影响。本综述旨在总结围绕镁 LSP 领域的现有研究。具体来说，阐明了对其机械、摩擦学、腐蚀和摩擦腐蚀特性相关的表面强化效应的理解。此外，还讨论了LSP用于关键行业镁材料的可行性。通过这项工作，可以对镁的LSP有一个新的认识，这可以为该领域的研究提供未来方向。
