Nickel is corroding in water with the standard hydrogen reaction serving as the counter reaction. Polarization testing has determined the following parameters for the Tafel slopes of each reaction to be: Ni2++2eNi,E0=0.257V,=0.1,i0=5107A/cm22H++2eH2,E0=0,=0.1,i0=4106A/cm2 Determine the corrosion potential Ecorr and corrosion current density icorr. Assume Tafel slopes for the cathodic and anodic direction of each reaction are the same. What is the rate of mass loss of Ni for the surface per unit area (in g/cm2 per year)? What is the rate of penetration in mils/year
