Popis: | Copper can be introduced into an iron charge by electroplating the latter with copper in a pyrophosphate electrolyte of the following composition: 50 CuSO4·5H2O, 200 K4P2O7, and 50 g/liter K2HPO, pH=7.5–8.9. The electrolyte operates in quite a stable manner at a temperature of 293–298°K and a circulation rate ensuring its complete replacement in the bath in 1 h. To obtain compact coatings of uniform thickness in a charge with up to 15% of copper, it is necessary to perform electrolysis at a current density of not more than 5 A/dm2 with a powder fill of 75 g/dm2. |
