For a corrosion rate calculation:
Faraday’s law
Mass(g) =I(ampere,C/s) *T (second) *AW( Atomic Weight,g/mol)/Z(charge)*96500
(C/mol)
Mass (g) /year = I * 31536000 * A.W. / Z * 96500
Mass (g) /year = 327 * I*AW/Z
Both side divided by D (Density, g/ cm3)
cm3/ year = 327 * I*AW/Z*D
Both side divided by surface area A (cm2)
cm/ year = 327 * I*AW / Z*D*A
Replace I/A with current density i (µA/ cm2) , I/A= 106 i
cm/ year = 327000000 * i*AW / Z*D
mm/ year = 32700000 * i*AW / Z*D
正确答案mm/year = 0
