The Reach on the Salt Spray Corrosion of 6000 Series Aluminum Alloys for the High-Speed Trains

Abstract:

In this study, we conducted salt spray corrosion test of 6005, 6082 aluminum, we can evaluate the salt spray corrosion performance of 6 series aluminum through the comparison of sample mass of different days before and after the experimental, the observation of the microstructure of the specimen as well as the analysis of corrosion products, etc. The experimental results showed that: 6 aluminum alloy corrosion is sensitive to salt spray corrosion , the degree of 6005,6082 aluminum corrosion increases with the increasing of etching time, but Substantially, corrosion rate increases with etching time in the beginning and then decreases . In the beginning the etching degree of corrosion of 6005 is less than 6082, with the etching time, the etching degree of corrosion of 6005 is greater than 6082 in the mid, and the etching degree of corrosion of 6082 is greater than 6005 in the last.
