| Abstract: |
| Objective To study the behaviors of galvanic corrosion which has been more serious along with the increasing dosage of CFRP used for aircraft, when connected with metal material. Methods An experimental test on galvanic corrosion between T700 carbon fiber composite material and 2A12 Aluminum alloy was carried out, which depended on the work environment of aircraft, including the temperature (0,10,20,30,40℃),the pH (3,5,7) and the NaCl concentration of electrolyte. Then, the influence of each parameter was well analyzed, so was the impact of galvanic corrosion on the material. Results Several conclusions were drawn at last. The corrosion current increased with time when the temperature increased, the concentration of NaCl rose and the pH decreased (in an acidic environment). Conclusion The galvanic corrosion had little impact on the composite material, while the corrosion of aluminum alloy was severe. |
