Nickel Plating

The most common electroless nickel is deposited by the catalytic reduction of nickel ions with sodium hypophosphite in acid baths at pH 4.5–5.0 at a temperature of 85–95°C. The bath can contain PTFE. The resulting plating contains typically 3–13% phosphorus by weight and perhaps 20–25% of PTFE by volume.
