Fundamental insights into the stabilisation and chemical degradation of the corrosion product scales

Abstract Carbonate stability plays a crucial role in clarifying the evolution and protection of the naturally formed corrosion scales on the steel surface in the application of geothermal production. In this paper, the stability of the corrosion scales from both micro and atomic level are studied vi...
