| Abstract: | Aluminium alloy/high strength steel connectors of one type aircraft have been subjected to the Xisha exposure testing and the change trend of connector corrosion was understood in this paper.The result showed that the ageing resistance of the connector coating was good.It can be effective to avoid galvanic corrosion and crevice corrosion with the wet fitting method.However,the bolts,nuts and rives(30CrMnSiA,cadmium-electroplated layer) on the back of the connectors were the weak points in the corrosion resistance.The protection should be strengthen. |
