Abstract

Método y dispositivo de protección catódica anticorrosiva por corriente impresa para superficies metálicas en contacto con un electrolito, en el que se utiliza un ánodo inerte, en donde se conecta y desconecta una corriente de protección en periodos sucesivos Pa y Pd, comprendiendo cada período Pd una fase de espera Fe, y una fase de medición y regulación Fmr en la que se mide una diferencia de potencial ΔV entre el potencial Vo en el ánodo inerte y la superficie metálica, y un potencial Vrefmin, en donde en la fase Fmr se mide el tiempo Δt que transcurre entre un instante to en el que se mide el potencial Vo, y un instante t en el que se alcanza el Vrefmin y se establece la magnitud de la corriente de protección y un tiempo de activación ta del siguiente período Pa, en función de ΔV y Δt.
