| Abstract: |
| A simulation accelerated corrosion experiment of a new type aero-engine compressor blade simulating service environment was carried out, and the corrosion resistance and corrosion damage evolution law of the compressor blade under service environment were examined. Electrochemical experiment were carried out with electrochemical workstation in typical environment of compressor material and corrosion current in typical environment was acquire. Combined with the existing airport environment spectrum and equivalent conversion algorithm, the airport environment spectrum was equivalently conversed using conversion coefficient obtained from corrosion current, the accelerated corrosion test spectrum for simulated follow-up service environment was compiled, and the accelerated corrosion test of compressor blade was carried out based on the obtained accelerated corrosion test spectrum. Local pitting corrosion of new type aeroengine compressor blade appeared at the 8 equivalent corrosion year, and with the prolongation of corrosion time, the corrosion damage degree is gradually aggravated. The new aeroengin compressor blades have good environmental adaptability in service environment and can meet the requirements of the fist turn. |
