Work out electroplating thickness instantly with clear inputs, formula shown and shareable results.
Plating thickness is Faraday's law followed by a geometry step: charge gives the deposited mass, and mass divided by density and area gives the thickness spread over the work. Nickel figures are used here (58.69 g/mol, divalent, 8.908 g/cm3). Two amps for thirty minutes over 100 cm2 at 95% efficiency lays down roughly 11 um.
Mass from charge
mass = (I x t x efficiency x M) / (n x F)
Thickness
thickness = mass / (density x area)
Some current goes into hydrogen evolution rather than metal. Real nickel baths run at 92-97%, so ignoring it overstates thickness.
No. Current density concentrates on edges and corners, so those plate thicker than recessed areas. This gives the average.
