The main results of the programme are:
1. We have used x-ray measurements to look at the growth of pits/attack underneath corrosion products. This information was published in:
a. Wang, C., Hua, Y., Nadimi, S., Taleb, W., Barker, R., Li, Y., Chen, X., Neville, A. "Determination of thickness and air-void distribution within the iron carbonate layers using X-ray computed tomography." Corrosion Science 179 (2021): 109153.
2. We have examined the chemistry of corrosion products and their structure and linked it to their ability to protect carbon steel. Published in the following papers:
a. Yong, H., Mohammed, S., Barker, R., Neville, A. "Comparisons of corrosion behaviour for X65 and low Cr steels in high pressure CO2-saturated brine" Journal of Materials Science & Technology 41 (2020): 21-32.
b. Yong, H., Xu, S., Wang, Y., Taleb, W., Sun, J., Zhang, L., Barker, R., Neville, A. "The formation of FeCO3 and Fe3O4 on carbon steel and their protective capabilities against CO2 corrosion at elevated temperature and pressure." Corrosion Science 157 (2019): 392-405.
3. We have incorporated ions/molecules into corrosion products to change their protective and mechanical properties, through the following publications:
a. Yong, H., Shamsa, S., Barker, R., Neville, A. "Protectiveness, morphology and composition of corrosion products formed on carbon steel in the presence of Cl−, Ca2+ and Mg2+ in high pressure CO2 environments." Applied Surface Science 455 (2018): 667-682.
b. Shamsa, A., Barker, R., Hua. Y., Barmatov, E., Hughes, T., Neville, A. "The role of Ca2+ ions on Ca/Fe carbonate products on X65 carbon steel in CO2 corrosion environments at 80 and 150° C." Corrosion Science 156 (2019): 58-70.
4. We have looked closely at deposits formed in highly toxic environments and linked their formation to localised corrosion. This was published in Corrosion Journal, but also presented at a US conference:
a. Pessu, F., Hua, Y., Barker, R., Neville, A. "A study of the pitting and uniform corrosion characteristics of X65 carbon steel in different H2S-CO2-containing environments." Corrosion 74, no. 8 (2018): 886-902.
b. Pessu, F. Hua, Y., Taleb, W., Charpentier, T., Barker, R., Chang, F., Chen, T., Neville, A. "Localized and general corrosion characteristics of carbon steel in H2S environments." In CORROSION 2019. OnePetro, 2019.
5. We have shown that corrosion products can support reactions at their surface which initiate localised attack, through the following publication:
a. Barker, R. Yazdi, R., Hua, Y., Jackson, A., Ghanbarzadeh, A., Huggan, A., Charpentier, T., Neville. A., "Development of an automated underwater abrasion rig to determine galvanic effects during the growth and localised breakdown of surface films in CO2-containing solutions." Review of Scientific Instruments 90, no. 3 (2019): 034101.
6. We have looked at the link between corrosion products and corrosion in high pressure environments. This was disseminated at a US corrosion conference:
a. Yong, H., Neville, A., Barker. R., "Corrosion behaviour of X65 steels in water-containing supercritical CO2 environments with NO2/O2." In CORROSION 2018. OnePetro, 2018.
