Abstract The present study investigates the influence of laser shock peening (LSP) on surface energy (SE) of AZ31B Magnesium alloy and its resilience to corrosion and tribocorrosion. AZ31B alloy was treated at different laser intensities. The S E and its interfacial components of treated surfaces were analyzed. The SE was found to be least at low laser intensity LSP. Lower interfacial SE showed decreased wettability, providing enhanced tribocorrosion resistance with respect to untreated surface. However, higher laser intensities increased the surface roughening effect, causing an increase in the interfacial SE and wettability of the surfaces, decreasing the tribocorrosion resistance. The study finds LSP can enhance tribological properties and mitigate the effects of corrosion and tribocorrosion.

激光冲击强化对AZ31B镁合金表面能和摩擦腐蚀性能的影响

摘要 本研究研究了激光冲击强化 (LSP) 对 AZ31B 镁合金表面能 (SE) 的影响及其对腐蚀和摩擦腐蚀的弹性。AZ31B 合金在不同的激光强度下进行了处理。对处理过的表面的 SE 及其界面成分进行了分析。发现 SE 在低激光强度 LSP 时最少。较低的界面 SE 表明润湿性降低，相对于未处理的表面提供增强的耐摩擦腐蚀。然而，较高的激光强度会增加表面粗糙化效果，导致界面 SE 和表面润湿性增加，从而降低耐摩擦腐蚀性。该研究发现 LSP 可以增强摩擦学性能并减轻腐蚀和摩擦腐蚀的影响。
