AI Technical Summary

Technical Problem

Existing radar-absorbing coatings are prone to corrosion in marine environments with high temperature, high humidity, and high salt spray, leading to a decrease in electromagnetic wave absorption performance and making it difficult to meet the corrosion protection and radar absorption requirements of shipborne aircraft and ships.

Method used

A method for preparing a TiO2-coated carbonyl iron modified anti-corrosion and microwave absorption composite material was adopted. The carbonyl iron was activated by acid, and ammonia and tetrabutyl titanate were added to prepare a TiO2 precursor, forming a CIP@TiO2 core-shell structure. The TiO2 layer acts as a physical barrier to protect the CIP from corrosion, and improves the microwave absorption performance through chemical bonding.

Benefits of technology

It enhances the coating's corrosion resistance and electromagnetic wave absorption properties, extends its service life, and is suitable for anti-corrosion and wave-absorbing coatings for shipborne aircraft and ships.
