Novelties in Electroplating

Abstract
This report covers three investigations: (1) Brilliant, multi‐colored electroplates were obtained from ammonium molybdate solutions. (2) A study of the codeposition of nickel and copper led to the development of a citrate‐cyanide bath. The bright hard alloy deposit contained from 60 to 80% nickel, balance copper, depending upon plating conditions which are specified. (3) Attempts to codeposit chromium with either copper or iron were unsuccessful.
