Thermal spray anodes for impressed current cathodic protection of reinforced concrete structures

Differences between thermal spray Zn and catalyzed thermal spray Ti, used f or impressed current cathodic protection of reinforced concrete structures, are reviewed. considerations include spray parameters, atomizing gases, sp ray rate, and costs, as well as physical properties, composition, and struc ture, comparisons of the effect of electrochemical aging on voltage require ments, bond strength, coating resistivity, water permeability, and anode-co ncrete interfacial chemistry are included.
