Abstract

PURPOSE: To enable the plating film of high corrosiveness to be formed over a high (low) current density renge by adding the limited amounts of chloride of alkaline eath metals to the bath containing the respectively specified amounts of NiCl2. 6H2O and H3BO3.
CONSTITUTION: Chloride of alkaline earth metals (e.g., BaCl2) is added at 5W 200g/l(10W100g/l) to the bath containing NiCl2.6H2O 70W400g/l(preferably 150W300g/l) and N3BO3 at 3g/l or over (7W30g/l). Or further NH4Cl is added at 50g/l or under. The resultant high stress Ni plating bath is used for micro-crack Cr plating process to form numerous micro-cracks in the Cr plating film thereby increasing the corrosion resistance of the plating.
