Abstract:The techniques and the mechanism of anodic bonding between aluminum and sodium borosilicate glass were analyzed. The effect of technical parameters on welding process was studied. It is pointed out that thermal expansion coefficient difference between them plays an important role in the bonding process, and the intimate contact area and the current are influenced by the bonding temperature and voltage . Trough analysing the joining mechanism, it is suggested that the interface is mainly made up of the compounds which contain silicon，aluminum， oxygen，sodium and zinc.
Key words: sodium borosilicate glass; aluminum； technical parameter； joining mechanism
