摘要

高速铁路接触网的铝合金部件在沿海地区暴露于腐蚀性介质时,面临着严重的腐蚀疲劳失效问题。因此,本研究制备了一种由喷丸表面纳米结晶前处理、微弧氧化(MAO)陶瓷涂层和丙烯酸树脂密封后处理组合而成的复合陶瓷涂层,用于高速铁路接触网用 6082-T6 铝合金。然后,研究了复合陶瓷涂层 6082-T6 铝合金的腐蚀和腐蚀疲劳性能。结果表明,前处理增加了陶瓷涂层的厚度,但会导致陶瓷涂层外表面连接处的内部缺陷增大,从而导致耐腐蚀性能比普通陶瓷涂层差。然而,由于陶瓷涂层下的基体内部存在压缩残余应力和晶粒细化层,与普通涂层试样相比,经过前处理的陶瓷涂层试样表现出更优越的腐蚀疲劳性能。此外,后处理还能有效减少涂层孔隙率,提高耐腐蚀性能。总之,本文中的复合陶瓷涂层表现出了卓越的耐腐蚀性、疲劳性和腐蚀疲劳性能。

Corrosion and corrosion-fatigue properties of composite ceramic coated aluminum alloy formed by combining surface nanocrystallization pre-treatment, micro-arc oxidation, and sealing post-treatment
The aluminum alloy components of the high-speed railway catenary, when exposed to the corrosive media in coastal regions, are confronted with a significant issue of corrosion-fatigue failure. Therefore, this study prepares a kind of composite ceramic coating formed by combining shot peening surface nanocrystallization pre-treatment, micro-arc oxidation (MAO) ceramic coating, and acrylic resin sealing post-treatment on 6082-T6 aluminum alloy used for high-speed railway catenary. Then, the corrosion and corrosion-fatigue properties of composite ceramic coated 6082-T6 aluminum alloy are investigated. Results indicate that the pre-treatment increases the thickness of ceramic coating, however results in larger internal defects connecting ceramic coating’s outer surface, leading to inferior corrosion resistance compared to plain ceramic coatings. However, owing to the presence of compressive residual stress and grain-refined layers within the substrate beneath the ceramic coating, ceramic coated specimens subjected to the pre-treatment exhibit superior corrosion-fatigue properties compared to plain coated specimens. Additionally, the post-treatment effectively reduces coating porosity and enhances corrosion resistance. In conclusion, the composite ceramic coating in this paper is demonstrated to exhibit a combination of superior corrosion resistance, fatigue and corrosion-fatigue properties.
