Chet Morrison Contractors is providing thermal sprayed aluminum (TSA) coating services in-house at its ISO-certified facilities. TSA coating is a process that uses an energy source to propel or spray small softened-metal particles onto the surface of another metal or structure.
TSA is applied on subsea assets to protect carbon steel from corrosion because it acts as a barrier, providing sacrificial protection. In seawater, aluminum has a low self-corrosion rate and is also anodic to carbon steel. Because the galvanic potential of aluminum is more active than carbon steel, TSA acts as an anode and provides a substantial level of cathodic protection.
