表面处理工艺对ZN-1阻尼材料粘接性能的影响

研究了不同表面处理方式、酸处理时间、酸处理中和剂及试件贮存时间等因素对ZN-1阻尼材料与硬铝的粘接性能的影响.结果表明采用浓硫酸对ZN-1阻尼材料进行表面处理,可以有效地改善其与硬铝的粘接效果;酸处理时间对ZN-1阻尼材料的表面形貌及其与硬铝的粘接强度无明显影响,但随着处理时间的增加,其表面的硫元素含量有增加的趋势;采用氨水、碳酸氢铵、碳酸氢钠、氢氧化钠水溶液或直接采用蒸馏水作为酸处理法的中和剂所制备的拉剪试样的破坏形式均表现为ZN-1阻尼材料破坏.此外,采用酸处理法制作的LY12/ZN-1/LY12粘接试样自然存放两年后其粘接强度基本没有变化.

Influence of Surface Treatment on Adhesion Performance of ZN- 1 Damping Material

Effect of the factors such as surface treatment of ZN-1 damping materials,the time of dipping in oil of vitriol,neutralizing agent of acid method and storage time of adhesion samples on the adhesion performance between ZN-1 damping materials and duralumin is investigated.The results show that the adhesion performance of ZN-1 damping materials can be improved through surface treatment with oil of vitriol.The surface morphology and adhesion performance of ZN-1 damping materials almost do not change with the time of dipping in oil of vitriol.Concentration of sulfur element on the surface of ZN-1 damping materials increases with the dipping time.Whether ammonia,ammonium bicarbonate,sodium bicarbonate,sodium hydroxide or distilled water as neutralizing agent of acid treatment,the adhesion samples of ZN-1 damping material are broken after shearing test.Furthermore,the adhesion performance of ZN-1 damping materials treated with oil of vitriol does not change after two years laying up in natural condition.
