2-Mercaptobenzimidazole, 2-Mercaptobenzothiazole, and Thioglycolic Acid in an Electroless Nickel-Plating Bath

Figure 4

Potentiodynamic polarization curves of the nickel platings electrolessly deposited using 2-mercaptobenzimidazole, 2-mercaptobenzothiazole, and thioglycolic acid. The measurements were made after the free-corrosion potentials had stabilized and were performed at room temperature in 3.5 wt% NaCl at a scan rate of 5 mV/s.
