Studies of bronze electrodeposition.

Studies have been carried out on a bronze plating solution using conventional current and pulsed current electrolyses at various bath temperatures and anode and cathode current densities under galvanostatic conditions. The results from these tests have been interpreted and a set of optimum bath conditions has been decided upon to achieve deposits of a desired composition and properties. Further studies have been carried out to determine the effect of bath composition, anode material and pulse frequency on the composition and structure of the deposits obtained.The deposits produced were analysed chemically by atomic absorption and X-ray fluorescence methods and studied structurally by X-ray diffraction. By application of the experimental data to the optimum plating conditions already specified a rudimentary mass balance for the system has been calculated. The possibility of developing a predictive control system for the bronze bath has been discussed in relationship to the mass balance.
