摘要：

通过一种简易化学清洗和腐蚀的方式，在金属表面获得微米级孔洞，并采用复合注射成型将金属和聚合物结合。通过溶液处理金属铝片时间变化得到不同尺度的表面微结构，研究表面微观结构对界面结合强度的影响规律。结果表明，经过盐酸处理过的金属铝表面表现出密集的微米级孔洞，随着腐蚀时间的增加，金属表面微孔孔径和微孔密度先增大后减小，界面结合剪切强度在孔径和孔密度的共同影响下先增大后减小，最大值为10.24 MPa；这一金属表面处理方式在汽车内饰、建筑装饰、电子产品外壳等领域提供工程化应用理论基础。

Abstract:

In this study, micro?scale pores were obtained on the metal surface by a simple chemical cleaning and etching method, and then a polymer was bonded with the resultant metal through composite injection molding. The surface microstructure was achieved at different scales by changing the dipping time of aluminum sheets in solution, and the influence of surface microstructure on the interface bonding strength was investigated. The results indicated that there were dense micro?sized pores on the surface of aluminum sheets after treated with hydrochloric acid. With an increase of corrosion time, the pore diameter and pore density of the metal surface increased at first and then tended to decrease. The interfacial bonding strength was found to increase at first and then decrease as a result of the combining effect of pore size and pore density, and it reached a maximum value of 10.24 MPa. This surface treatment method provides a theoretical foundation for engineering applications in the fields of automotive interiors, architectural decoration and electronic product enclosures.
