%X This paper presents a mathematical model of pitting corrosion formed by eight non-linear coupled differential equations and their boundary equations. In this model we studied the effect of the variation of parameter values (temperature, crevice depth, oxygen and sodium chloride concentration outside the cavity, and pH) on all the concentrations of the species, and on their differences with their concentrations outside the crevice and along the cavity using the network method. Moreover, a sensitivity study of the system parameters has been carried out. No simplifications have been considered, although the model is firmly coupled and susceptible to any variation of the aforementioned parameters. The development of the model is clearly explained. The results are compared with data published in the scientific literature for domains that establish the most complex and complete scenarios to verify the reliability of the model. One of the practical applications of this work, among others, is focused on the possible effects of this type of corrosion on the reinforced concrete, in buried pipes and on ship hulls.
