| Abstract: |
| The work aims to study the effect of natural environmental factors on corrosion of aluminum alloys, and explore the effect law of environmental factors on corrosion of aluminum alloys. The effect of environmental factors on the average corrosion rate of seven aluminum alloys was analyzed by multi-layer perceptron neural network. The important factors affecting the corrosion damage of aluminum alloy were Cl–deposition rate, SO2 deposition rate, NOx deposition rate. The auxiliary factors were annual rainfall, annual fog and dew hours, relative humidity, annual sunshine hours, temperature, and chemical composition. The secondary factors were annual precipitation hours and PH of rain. The analysis based on the multi-layer perceptron neural network effectively demonstrates the effect of environmental factors on the average corrosion rate of aluminum alloys. |
