Abstract
549,954. Electro-deposition of iron. UNITED STATES RUBBER CO. July 4, 1942, No. 9265. Convention date, Oct. 18, 1941. Addition to 543,137. [Class 41] Iron is deposited in the manner described in the parent Specification from a solution containing ferrous chloride, calcium chloride, and ferric chloride, a ferric ion concentration of between 01 and .45 grams per litre being maintained in the solution and a pH value lying between .8 and 1.4, the bath being worked at a temperature of from 85 ‹ - - 90 C. The curves A, B of Fig. 2 show the relation between pH value and the maximum ferric ion concentration which can exist in the solution as represented by the oxidation potential measured by a gold electrode and a standard saturated calomel electrode, the area of effective operation lying under the curve B, which takes into account the decrease in solubility caused by the ageing of the precipitate.
