Differences between thermal spray Zn and catalyzed thermal spray Ti, used for impressed current cathodic protection of reinforced concrete structures, are reviewed. Considerations include spray parameters, atomizing gases, spray rate, and costs, as well as physical properties, composition, and structure. Comparisons of the effect of electrochemical aging on voltage requirements, bond strength, coating resistivity, water permeability, and anode-concrete interfacial chemistry are included.
