Synthesis of Co Diffused Cu matrix for Applying Moessbauer Source

To establish the coating conditions for ⁵⁷Co, nonradioactive Co ions are dissolved in an acid solution and electroplated on to a copper plate. Then, the thermal diffusion of electroplated Co into a copper matrix was studied to apply a ⁵⁷Co Moessbauer source. Nanocrystalline Co particles were coated on a Cu substrate using DC electro-deposition at a pH of 1.89 to 5 and 20-30 mA/cm². The average grain size was up to 54 nm as the pH increased to 5. The second phase of Co-oxide was formatted as the pH was increased above 4. The influence of different annealing conditions was investigated. The diffusion depth of Co depends on the annealing temperature and time. Charged Co ions are formed by sulfate, sulfamate, chloride, and a Watts bath. However, charged ⁵⁷Co ions are formed by dissolving metal ⁵⁷Co. To establish the coating conditions for ⁵⁷Co, non-radioactive Co ions are dissolved in an acid solution and electroplated on to a copper plate.
