Thermal-Sprayed Zinc Anodes for Cathodic Protection of Reinforced Concrete Structures

摘要

Thermal-sprayed zinc anodes are used to cathodically protect rebar from corrosion in reinforced concrete structures. Research was conducted to determine the useful lifetime of theses anodes and the need for special surface treatments prior to spraying. Half of the samples were heated prior to being thermally-sprayed with zinc; the other half remained unheated. The preheated samples had initial zinc-concrete adhesion strengths that were 80
