摘要：
The paper describes the application of the maximum entropy production rate to the calculation of uniform corrosion current density. The surface is described as ensemble of randomly moving microcells. In the assumption that both ohmic drops (eta(Omega)) and polarization overvoltages (eta(Delta)) are negligible, the theory allows to determine a formula for corrosion current density that takes into account the areal ratio between anodic and cathodic sites.
