摘要
为降低表面质量对粘接副力学性能的影响,提高胶粘剂质量一致性检验的准确率,对胶接试片的表面处理进行了相关研究。针对LY12-CZ铝合金不同的表面处理状态和不同的胶粘剂体系开展了研究,结果表明,磷酸阳极化铝合金粘接副的拉剪强度比未阳极化铝合金粘接副拉剪强度提高了50%,剥离强度提高了162%。磷酸阳极化铝合金剪切试件和剥离试件的破坏模式均为内聚破坏,而未阳极化处理的铝合金剪切试件的破坏模式为混合破坏。
In order to reduce the influence of the lap surface to strength, improve the accuracy rate of adhesives inspection, some research is studied on the lap surface. The aluminum alloy is anodized in phosphoric acid solutions, and the lap shear strength and peeling strength of different adhesives in the adherents is analyzed. It is tbund that the lap shear strength of the bond, in which the adherends are anodized ,is 50% larger than that of the non- anodized .The lap peeling strength of the bond, in which the adherends are anodized ,is 162%larger than that of the non- anodized. The cohesion failure rnode has been found in the adherends which is anodized. The mixed failure mode has been found in the lap shear strength of the bond which is non-anodized.
