Chrome Electroplating

Cr³⁺ + 3e⁻ → Cr

Genel Bakış

Chromium plating deposits a thin layer of chromium from a chromic acid or trivalent chromium bath. Decorative chrome is only 0.25–0.5 μm thick over a nickel undercoat, while hard chrome (industrial) is 20–250 μm thick. Chrome provides exceptional hardness (68–72 HRC), corrosion resistance, and a mirror-like finish.
