Alloy M is being evaluated for use in marine environment. The Evans diagram of the alloy is shown in Figure 3. 0.84 0.6 02+2H20 +4e 4e 40H Potential (V) 0.4 MMA++ne 0.2 Mw+ne M 100 10-6 10-4 10-2 Current density (Acm-2) Figure 3 a) Determine the corrosion current. b) Determine the corrosion current when an impressed current corresponding to reduction of 0.1 V was applied. c) Determine voltage reduction needed to reduce the corrosion current density by a factor of 1000. d) Determine voltage reduction needed to stop corrosion. (Hint: Consider corrosion to be stopped at open voltage of Alloy M)
