Abstract

1368749 Electro-depositing chromium BRITISH NON-FERROUS METALS RESEARCH ASSOCIATION 29 Sept 1972 [30 Sept 1971] 45669/71 Heading C7B Chromium is electro-deposited from a solution of trivalent chromium, ammonium and halide ions, e.g. added as CrCl 3 and NH 4 Cl, in a homogenous liquid mixture of water and a dipolar organic compound containing a highly electro-negative oxygen atom (e.g. activated by an adjacent electrondonating atom or group) e.g. dimethylformamide, the proportion by volume of water to dipolar organic compound being not greater than 95À5, containing at least 5 p.p.m. of a surfactant, preferably a quaternary ammonium compound e.g. cetyl trimethyl ammonium bromide; other surfactants specified are Na lauryl sulphate and substituted imidazoline. The bath may also contain NaCl and boric acid. Specifications 1368748 and 1144913 are referred to.
