| Objective To improve the corrosion prevention level of the frequently dismounting area of steel fastener．Methods The salt fog test was used to review the impact on the frequently dismounting steel fastener area. The improving scheme was established, which was validated by accelerated corrosion test. Results The frequently dismounting and assembly had significant breakage effect on the defense coatings of the fastener area. Corrosion prevention level was markedly improved by replacement of surface treatment approaches, fastener hole wall prevention， assembly seal and application of corrosion inhibitor. Conclusion Corrosion protection measures can effectively solve the corrosion problem in the frequently dismounting area of steel fastener，which could be popularized in aircraft manufacture and maintenance. |
