“…The Mössbauer spectroscopy requires sources that emit narrow un-split lines. The 57 Co/Rh source is fabricated as follows: the first step electroplating a 57 Co required radioactive isotope onto the surface of an Rh substrate, and the second step is for thermal diffusion at high temperature into its crystal lattice [2][3]. Well-known methods developed for the electrodeposition of cobalt are inadequate for the electroplating of carrier-free isotopes.…”

To establish the coating conditions for 57 Co, non-radioactive Co ions are dissolved in an acid solution and electroplated on to a rhodium plate. The thermal diffusion of electroplated Co into a rhodium matrix was studied to apply a 57 Co Mössbauer source. The procedure to form a Co deposited onto Rh foil was established using two different electroplating baths: the acid-based buffer (pH 3) containing boric acid, sodium chloride, and saccharin, and the alkaline-based buffer (pH 10) containing hydrazine hydrate and ammonium citrate. The influence of different annealing conditions was investigated. From the results, the best diffusion degree of electrodeposited Co onto the rhodium matrix was obtained in an annealing process performed at 1100°C for 3 h in vacuum over10 -5 hPa.

The presented work outlines the methodology employed in the preparation of two distinct Mössbauer radiation sources, characterised by their respective emission properties. Two matrices were selected for the electrodeposition and subsequent high-temperature diffusion of 57Co. The objective was to prepare a single-line and a six-line source, with emission spectra that overlap the absorption spectra of selected steel phases (namely, paramagnetic austenite and ferromagnetic ferrite/martensite). The rationale behind the aforementioned source preparation is to develop a bespoke apparatus based on the Mössbauer principle for the rapid determination of the aforementioned steel phases.
