The chemical plating process for magnesium-base material includes the following steps: 1. alkaline dewaxing the magnesium-base material; 2. activating with acid solution containing fluoric salt and no chlorine ion and in pH 2.0-5.0, and treating with alkaline neutralizing solution containing alkali metal salt of pyrophosphoric acid, fluoric salt and hypophosphite in pH 8.0-12.0; 3. chemical nickel pre-plating with the plating solution containing nickel salt in 10-80 g/L concentration, fluoric salt in 5-50 g/L concentration, pyrophosphite in 20-100 g/L concentration and no chlorine ion and in pH 5.0-9.0; 4. chemical nickel plating with the plating solution containing nickel salt in 10-100 g/L concentration, pyrophosphite in 10-80 g/L concentration and no chlorine ion and in pH 3-7; and 5. optional heat treatment. The said process can form homogeneous compact nickel layer with sufficient binding force on magnesium-base material. |
