Electro-Chemical-Grinding-Machining

Composition of a Nickel superalloy is as follows: Ni = 70.0%, Cr = 20.0%, Fe = 5.0% and rest Titanium. What will be rate of dissolution if area of tool is 1500 mm2 and a current of 1000 A is being passed through cell? Assume dissolution to take place at lowest valency of elements.
ANi = 58.71 ρNi = 8.9 νNi = 2
ACr = 51.99 ρCr = 7.19 νCr = 2
AFe = 55.85 ρFe = 7.86 νFe = 2
ATi = 47.9 ρTi = 4.51 νTi = 3

Discrepancies are sometimes observed between theoretical and actual metal removal rates and electrode feed rates.

Composition of a Nickel superalloy is as follows: Ni = 70.0%

Cr = 20.0%

Fe = 5.0% and rest Titanium. What will be the rate of dissolution if the area of the tool is 1500 mm2 and a current of 1000 A is being passed through the cell?
