Two-month experiments were carried out with carbon steel electrodes buried in an artificial sand wetted at 50–55% of saturation with a 0.07 mol L−1 Na2SO4·10H2O solution. Various protection potentials (corrected from the ohmic drop) were applied

Corrosion poses a significant risk to critical infrastructures. Practice indicates that metro-induced stray current corrosion is a significant threat to underground infrastructures, which may be an obstacle to expanding the subway transportation netw

Among the failure modes of high-grade steel pipelines, cracking or leakage failures of girth welds account for nearly 1/3 in total. Thus, different assessment methods are adopted for various types of indicators, and a risk assessment method based on

A forecast of the corrosion activity within different landscapes of the cryolithozone is poorly studied previously. This study represent a close correlation between the proportion of corroded sections of the gas pipeline route of the gas field Medvez
