摘要：

Aluminum-plastic hybrid joints have become increasingly important due to weight reduction in the engineering field. Previous studies claimed that aluminum surface conditions are critical for the hybrids. However, the influence of the surficial adsorbed water, which always covers the aluminum surface at normal ambient conditions, is rarely known. This paper investigated the influence of the surficial adsorbed water through a combined experimental and simulation approach. We prepared aluminum plates with different surficial adsorbed water amounts and fabricated aluminum/polyamide 6 (PA6) hybrids. The bonding strength was measured. The aluminum surface was characterized by various methods to understand its surficial adsorbed water conditions. Molecular dynamics were also performed and compared with experimental results. The results clarified that the surficial adsorbed water influences the bonding strength of metal-plastic hybrids greatly at a molecular level, which will significantly contribute to the knowledge of metal-plastic hybrids.
