| Abstract: |
| Objective tostudy the corrosion damage of thejet blastdeflector.Methods Based on the structure characteristics of the Jet blast deflector, the classification method and reason for corrosion were analyzed, and the properties of corrosion damage of jet blast deflector were studied.Resultsthere were exfoliation corrosion in the connecting parts of the flats, pitting in the panel, high-temperature corrosion in the antiskid coating, and crevice corrosion in the motion actuators. Conclusion the characteristics of corrosion were discussed, and the corrosion protective measures in production and routine maintenance were proposed. |
