This study reports the development of frits with different composition, time, and firing temperature for mitigating the corrosion of AA2024, AA6082, and AA7075 aluminium alloys in chloride‐containing solutions. The melting points of the frits were determined using a heating microscope, while the thermal expansion was measured using dilatometry. Several frits were prepared, of which seven were coated on AA2024, AA6082 and AA7075 aluminium alloys. The corrosion resistance of the coated samples was tested in 5 wt% NaCl solution at 25°C using potentiodynamic curve measurements. The corrosion resistance of the coated samples increased compared with the respective uncoated aluminium alloys. The composition and in‐depth homogeneity of the best‐performing coated samples were confirmed using a gas cluster ion beam sputtering source associated with X‐ray photoelectron spectroscopy analysis. Furthermore, O₂⁺ sputtering was performed in association with time‐of‐flight secondary ion mass spectrometry to describe the three‐dimensional composition of the frits.

用于增强AA2024，AA6082和AA7075铝合金的玻璃料的开发和分析

这项研究报告了不同成分，时间和焙烧温度的玻璃料的发展，这些玻璃料可减轻AA2024，AA6082和AA7075铝合金在含氯溶液中的腐蚀。使用加热显微镜确定玻璃料的熔点，而使用膨胀计测量热膨胀。制备了几种玻璃料，其中七个涂覆在AA2024，AA6082和AA7075铝合金上。使用电位动力学曲线测量，在5 wt％NaCl溶液中于25°C下测试了涂层样品的耐腐蚀性。与相应的未涂层铝合金相比，涂层样品的耐腐蚀性提高了。使用与X射线光电子能谱分析相关的气体团簇离子束溅射源，可以确定性能最佳的涂层样品的成分和深度均匀性。此外，O飞行时间二次离子质谱联用₂ ⁺溅射来描述玻璃料的三维成分。
