Carbon steels such as API 5L X65 are widely used oil and gas exploration, production and transportation service. However, these steels tend to corrode in the presence of wet CO2 and corrosion is more pronounced in the presence of dissolved salts and acids. Other metals, alloys and polymers also degrade in the presence of high pressure gaseous and supercritical CO2. The corrosion rate of carbon steels in some aqueous environments have been reported to be more than a few millimeters per year.9-10 The situation could be further exacerbated by H2S where cracking can be an issue for high strength steels.

Carbon steels and low alloy steels are the workhorse of several industries where properties such as strength, fracture toughness and weldability play a key role. In addition to these properties, carbon steels are also the most cost effective materials is several applications. Of particular interest is the API 5L X65 which is widely used in oil and gas exploration, production and transportation service.

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.
