Abstract

The invention discloses a local corrosion-resistant scanning type micro-arc oxidation treatment process for a shipboard aircraft. The process comprises the following steps: polishing and completely washing a to-be-repaired area of a part; setting an insulating layer on the edge of the to-be-repaired area and setting a flow guide glue strip in the to-be-repaired area; starting a scanning type micro-arc oxidation treatment device, uniformly spraying electrolyte in the to-be-repaired area to perform micro-arc oxidation reaction on the to-be-repaired area, generating a micro-arc oxidation ceramiclayer in the to-be-repaired area and turning off the scanning type micro-arc oxidation treatment device; cleaning the micro-arc oxidation ceramic layer and blow-drying with hot air. The process and the device are suitable for repairing the to-be-repaired part on site, the parts do not need to be disassembled, the repairing efficiency is improved, and the repairing difficulty is reduced.

Description

【Technical field】 [0001] The invention belongs to the technical field of light metal surface protection of shipboard aircraft, and in particular relates to a scanning micro-arc oxidation treatment process and device for partial anticorrosion of shipboard aircraft. 【Background technique】 [0002] Carrier-based aircraft refers to the aircraft that take off and land on the aircraft carrier. Its performance determines the combat effectiveness of the aircraft carrier. The more carrier-based aircraft are, the stronger the strength is. exist. [0003] The carrier-based aircraft can adapt to the ocean environment. Generally, it can still take off and land on the aircraft carrier under the sea conditions of grade 6 wind and waves of grade 4 to 5. The surface skin and internal components of carrier-based aircraft are mostly made of aluminum alloy, and there is no standard treatment equipment available for the surface anti-corrosion treatment, and there is no existing process specific...
