Mr. Jorge Costa , Structural Technologies, Pompano Beach, FL
Corrosion of reinforcing steel and other metallic embedments in concrete is a significant problem affecting the infrastructure for the transportation, energy, defense, commercial and utility sectors, among others.  Cathodic protection has been proven as an effective technology for the mitigation of corrosion of reinforced concrete structures in these areas.  Thermal spray technology has been used successfully to install anodes on the surface of concrete structures.  These anodes are an integral component of the cathodic protection systems, necessary to operate the corrosion protection systems properly.  This presentation will outline the installation of anodes on concrete structures using thermal spray techniques.  The performance of the installations will be discussed addressing alloy composition and application technique.  Several case histories will be presented to conclude.
