| Abstract: |
| The work aims to studythe effect of typical marine atmospheric environment in Nansha Islands on corrosion behavior of GH901 superalloy. The atmospheric exposure test of GH901 superalloy was carried out in a typical environment of Mischief Reef in Nansha and the corrosion characteristics of GH901 superalloy were analyzed by metallographic microscope. The tensile strength of the material was tested periodically and the appearance and morphology of the specimen were analyzed. After one year of atmospheric exposure, there was no obvious corrosion on the matrix surface of GH901 superalloy tensile specimen. The tensile strength and elongation at break fluctuated slightly under the condition of high temperature mechanical test at 575 ℃, but the mechanical properties at high temperature did not change obviously with the extension of test time in short-term natural exposure. GH901 superalloy tensile specimen has good corrosion resistance and good mechanical property stability at 575 ℃ after short-term island atmospheric exposure. |
