Contexto: "This excess of alkalinity and induced passivity also has an effect on the anodic behaviour, since the anodic currents (in a region close to the corrosion potential) are lower than those recorded when the anodic potentiodynamic polarization is initiated at the corrosion potential."

Definição: "The method presented here, based on the measurement of the hydrostatic force generated by the hydrogen evolved during corrosion clearly enables to investigate with unprecedented precision the corrosion behaviour of magnesium, thanks to polarization tests, allowing to obtain information about the corrosion mechanisms, corrosion rate, passivity and susceptibility to pitting of materials in specific environments."
