Composition of a Nickel superalloy is as follows: Ni = 70.0%, Cr = 20.0%, Fe = 5.0% and rest Titanium Calculate rate of dissolution if the area of the tool is 1500 mm2 and a current of 2000 A is being passed through the cell. Assume dissolution to take place at lowest valency of the elements.

ANi = 58.71 Ni = 8.9 Ni = 2

ACr = 51.99 Cr = 7.19 Cr = 2

AFe = 55.85 Fe = 7.86 Fe = 2

ATi = 47.9 Ti = 4.51 Ti = 3
