Influence of phosphating treatment on the mechanics performance of adhesive/metal interface

The metal surface was treated with phosphating treatment,and the mechanics performance of the adhesive/metal interface was tested.The influence of fatigue loading on the adhesive joint before and after surface treatment was analyzed,and the changes of chemical bond before and after fatigue were analyzed,too.The results showed that after the phosphating treatment,the anti-fatigue performance of the adhesive joint became better.
