摘要(Abstract)：

采用冷喷涂技术在GWK61(Mg-6.0Gd-1.0Y-0.4Zr)稀土耐热镁合金表面制备了纯Al涂层，研究了时效工艺对GWK61镁合金与冷喷涂纯Al涂层的界面扩散行为及微观组织的影响。结果表明：在时效处理过程中GWK61合金与Al涂层间发生了界面扩散反应，形成了金属间化合物(IMC)层，靠近GWK61合金一侧形成的是Mg_(17)Al_(12)(γ相),靠近Al涂层一侧形成的是Al_3Mg_2(β相),其厚度均随时效温度的升高和时效时间的延长而增大；在175℃时效96 h后β相和γ相的厚度分别为1.7和0.9μm,在190℃时效96 h后的厚度分别为2.8和1.3μm; β相的生长速率高于γ相，两者的生长都遵循抛物线定律；在时效处理过程中Al涂层发生了静态再结晶，位错密度显著降低，这有利于提高其耐腐蚀性。
