This paper reports the performance of thermally sprayed aluminium (TSA) in an aqueous solution pressurized with 10MPa supercritical CO2 at 40°C. Carbon steel specimen (BS EN 10025 S355) was coated with TSA and exposed to 3.5 wt.% NaCl solution pressurised with 10MPa CO2. The specimen was taken out after the 168h test and post-test examination was carried out. Post-test visual examination indicate no significant signs of damage which was confirmed by microstructural characterization. The SEM micrographs indicated promising behaviour of TSA with no corrosion was seen at the TSA-steel interface. However, one must note that the test was carried out for 168h and such short term test seldom give long-term corrosion performance. Nonetheless, the initial results looks interesting and provides some indication of TSA’s promise for protection of steel against CO2 corrosion.
