Abstract
Abstract A method for determining corrosion rate from electrochemical polarization data obtained in the region of the corrosion potential is described. The technique has foundation in theory, is supported by experimental evidence, and appears to have widespread application. The advantages and limitations of the method are discussed. It would appear that the use of linear polarization measurements can supply valuable information regarding: (1.) Studies of the effect of environment variables on corrosion rate. These include changes in composition, velocity, and temperature, (2.) Evaluations of inhibitors in controlling corrosion, (3.) Comparison of the corrosion rates of various alloys of similar composition in a given environment, and (4.) Determination of changes in corrosion rate with time, including studies of underground structures as well as materials in aqueous solutions. It also may be possible to use this method in evaluating the condition of coatings in service which cannot be inspected by visual ...
