Effect of Adhesives on Static Properties of Self-piercing Riveted Joints under Acidic Environment

  • 摘要: 以AA5052-AA5052自冲铆接头(MJ)和AA5052-AA5052粘-铆复合接头(ZM)为研究对象,0.02 mol/L的NaHSO3溶液作为腐蚀液,通过干湿周浸实验、静力学测试和能谱分析,对失效载荷、失效形式以及形貌变化进行分析,对比两组接头的静力学性能。结果表明:粘接剂的使用,对接头静强度有一定的促进作用;由于腐蚀产物的影响,接头静强度均呈现先减小后增大的趋势;粘接剂减小接头的能量吸收值,腐蚀时间对接头缓冲吸震的能力未产生较大影响;MJ失效形式均为T型失效,ZM分为T型和C型失效,接头失效形式也受粘接剂的影响;板材表面成分和铆钉腐蚀后也发生明显变化。
