| Abstract: |
| The paper aims to compile environment spectrum of accelerated corrosion test of a new type of aeronautical material. The electrochemical corrosion experiment of the material under different NaCl solution conditions was carried out, and the open circuit potential and corrosion current of different condition test was analyzed through polarization curve. Combined with equivalent algorithm, the equivalent relationship between different NaCl solution condition was computed. At 35 ℃, the corrosion current of the new type of aeronautical material increased with the concentration increase of sodium chloride. At 3.5% sodium chloride, the corrosion current increased with the increase temperature. The specific value of equivalent relationship is different with different environment conditions. |
