Abstract

The effect of additives such as complexing agents, stabilzers and boric acid on the bath stability and the deposition rate of electroless black Ni-Zn plating has been examined. The deposits obtained became black and showed an amorphous structure. The significant increasing in the deposition rate was not found when only glycine and citric acid were used as complexing agents. The deposition rate increased up to 3 and 4 times by adding malic acid and glycolic acid as an additional complexing agent, respectively. The stabilizers and the boric acid, however, had little influence on the deposition rate.
