摘要：

In the present work, the laser surface desensitization (LSD) successfully reverse the sensitization of AA5083 alloy and improve the resistance to re-sensitization, which improve the service life of AA5083 alloy potentially. Nitric acid mass loss tests, immersion tests and electrochemical tests confirmed that the intergranular corrosion resistance of the LSD treated sample after re-sensitization could be higher than sensitized sample, which is mainly ascribed to the appropriate desensitization layer depth and surface degree of sensitization value by LSD. Accompanied with the dissolution of grain boundary (3 (Al3Mg2) phase during LSD process, the grain boundaries could be characterized by Mg segregation or nano-sized Mg-rich clusters, and Mg-rich precipitates could be increases in the grain. During the re-sensitization process, Mg diffused towards dispersoids or Mg-rich precipitates within grains, which inhibited the continuous formation of grain boundary (3 phase. Slow strain rate tensile test also confirmed the improvement of stress corrosion resistance of LSD.
