Electroplating Thickness Calculator
Deposit thickness from current density and time via Faraday's law.
Nickel at 3 A/dm² lays ~0.6 µm/min. Chrome's pathetic 13% efficiency is why hard-chrome takes hours and why shops switched to HVOF spray. Current DISTRIBUTION ruins corners — thickness varies 2:1 across real parts.
Formula
Electroplating Thickness Calculator is a free electroplating thickness for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Electroplating Thickness Calculator
Deposit thickness from current density and time via Faraday's law. The calculation implements δ = j·t·M·η/(z·F·ρ) (Faraday) (Faraday's laws; Electroplating Engineering Handbook). Nickel at 3 A/dm² lays ~0.6 µm/min. Chrome's pathetic 13% efficiency is why hard-chrome takes hours and why shops switched to HVOF spray. Current DISTRIBUTION ruins corners — thickness varies 2:1 across real parts.

Frequently asked questions
What formula does the Electroplating Thickness Calculator use?+
It computes δ = j·t·M·η/(z·F·ρ) (Faraday), per Faraday's laws; Electroplating Engineering Handbook. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
Nickel at 3 A/dm² lays ~0.6 µm/min. Chrome's pathetic 13% efficiency is why hard-chrome takes hours and why shops switched to HVOF spray. Current DISTRIBUTION ruins corners — thickness varies 2:1 across real parts.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Electroplating Thickness Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
