Preparation of Rust Removing Solution for Radar Corrosion Maintenance at Positions

In view of the characters of radar corrosion maintenance at positions, a chemical rust removing solution was prepared by orthogonal tests. This solution can remove the corrosion products on severely corroded steel surface quickly by brush coating or smear technique at ambient temperature. SEM-EDAX analyses and performance tests showed that a zinc-ferric system phosphate coating with relative corrosion resisting property was presented after treatment by the solution, the solution had good compatibility with original coating. The phosphate coating can be used as a good bottom layer for painting. All of these properties meet well the requirements of radar corrosion maintenance at positions.
