  • 摘要: 为有效改善AZ31镁合金表面的腐蚀性能,本文采用激光熔覆技术在AZ31镁合金表面成功制备了无缺陷的Al-TiC复合涂层。研究了不同成分含量的Al-TiC复合涂层的相组成、微观组织和耐腐蚀性能的影响。结果表明:在Al-TiC复合涂层内形成了大量的Al12Mg17、Mg2Al3和TiC相。复合涂层内微观组织呈现出连续网络状分布特征。随着Al-TiC混合粉末中Al含量的减小,复合涂层中Al12Mg17、Mg2Al3和TiC相的含量呈递增趋势,网络状分布的微观组织结构变得更加均匀连续。复合涂层与AZ31基体之间形成了良好的冶金结合界面。激光熔覆制备的Al-TiC复合涂层耐腐蚀性能较AZ31基体显著提升。自腐蚀电位由基体的−1.563 V提升至−1.144 V,自腐蚀电流由基体的1.55×10−4 A减小至2.63×10−6 A。
