The aim of this work was to study the application of external anode-type active interception rust-proof technology in preservation of air spares. The aircraft engine cylinder and crankshaft were sealed using interception rust-proof bags with a thickness of 100 μm and interception translucent rust-proof films with a thickness of 80 μm, and the air spares were checked after preservation. No corrosion phenomenon was found on the sealed air spares after depreservation. In conclusion, this technology could effectively seal aviation materials and simplify the preservation and depreservation workflow.
