Abstract Share this page

.Tripolyphosphate electrolytes can be employed for the production of tin bronze powders whose composition and particle size can easily be controlled by changing deposition conditions. 2. The basic relationships between electrolysis parameters and alloy composition and cathodic current efficiency established in a study of the electrodeposition of dense bronze coatings are observed also in the production of electrolytic powdered alloys from TPP electrolytes. 3. The optimum conditions for the preparation of tin bronze powders from TPP electrolytes have been determined. The electrolyte compositions for the deposition of white and yellow bronze powders are (mole/liter) sodium TPP 0.55 each, copper sulfate 0.105 and 0.126, respectively, and tin chloride 0,035 and 0.014, respectively. The optimum process parameters are pH 6–8, t=30–40°C, Dc=15–25 A/dm2, electrolyte agitation. Translated from Poroshkovaya Metallurgiya, No. 2(158), pp. 1–4, February, 1976.
