Unformatted text preview: EMA 4324 Problem Set 7 3-6. Using appropriate polarization diagrams, determine the effect of the following parameters on the corrosion potential and corrosion rate of metal M corroding to M + in an acid solution: [a] increasing j o of the anodic reaction, [b] increasing j o of the cathodic reaction, [c] increasing the concentration of dissolved [H + ] and [d] increasing the Tafel constant for the anodic reaction. ****************************************************** Starting condition - note positions of corrosion potential and corrosion current increase j o (a) increase j o (c) increase j o (c), E eq increase (a) decrease increase increase b (a) increase increase increase [H + ] increase increase increase j o (c) increase decrease increase j o (a) I corr E corr parameter potential l o g 1 c u r r e n t I cor E c o r r potential l o g 1 c u r r e n t I cor E c o r r potential l o g 1 c u r r e n t I corr E c o r r potential l o g 1 c u r r e n t I cor E c o r r potential l o g 1 c u r r e n t I corr E c o r r 3-8.
