| Abstract: | A new citrate electroplating bath for bright tin-lead alloys was studied. By adding new bright additives in a concentration of 0.5 g/L MHA and 4.5 g/L MTA, not only a bright plating was obtained but also the surface crystals, the throwing and covering power of the bath was considerably improved. Besides, the cathodic current efficiency was remarkably increased. The results of the polarization curve study showed that the cathodic polariza-bility was obviously increased. |
