Abstract

In high speed electroplating with nickel from an acid bath to provide a bright levelled deposit, the bath contains phenylpropiolamide, the cathode current density is at least 10 amps/dm2 and the bath is moved over the cathode at high speed. If phenylpropiolamide is used alone the bath should contain it in a concentration of at least 0.8 g/1 while if a sulpho-oxygen brightener is present also the concentration may be from 0.2 to 0.6 g/1. The bath may be a Watts type, sulphate, sulphamate or chloride bath, operating temperatures may be 60 to 80 DEG C., the bath-cathode velocity may be from 60 to 320 cm/sec., and current densities of up to 120 amps/dm2 may be used. Nickel or insoluble, e.g. lead, anodes may be used.
