Monitoring Nickel-Plating Baths in Surface Engineering

Equations 1 and 2 demonstrate that the bath's chemical composition changes over a period of time. The hypophosphite content and the nickel ion decrease, and orthophosphite and sulfate concentrations (NaH 2 PO 3), which are products of increasing salinity, increase.Normally, baths contain nickel salt in the form of nickel sulfate, and nickel is autocatalytically deposited.
