Metal Finishing – Plating & Coating
Electrolytic Nickel Plating
Electrolytic nickel plating; provides wear and corrosion resistance, also used for controlled thickness build-up in repair work.
Process
A nickel layer is deposited electrolytically onto the base material. Applied for corrosion and wear resistance as well as decorative finishes.
What it provides
- Wear and corrosion resistance; bright and matte options
- Controlled thickness build-up for repair
- Base layer under chrome, gold and other top coats
Frequently asked questions
What is the difference between electrolytic and electroless nickel?
Electrolytic nickel is deposited with current, so thickness follows current distribution: heavier on outer surfaces, thinner in recesses. Electroless nickel is autocatalytic and builds an even thickness everywhere, including bores. Electrolytic suits wear and decorative work; electroless suits complex geometry.
What thicknesses are applied?
Typically 5–50 µm to specification; heavier build-up is possible for repair. Thickness is measured by X-ray fluorescence and reported.
