Electrodeposition of cadmium-lead alloys: part 1—fluosilicate electrolytes

Summary

The literature relating to cadmium-lead alloy electrodeposition has been surveyed in relation to the requirements of lead-rich bearing alloys. Experimental work is reported showing that a fluosilicate solution enables such alloys to be produced, a preferable solution composition being based on 220 gl⁻¹ cadmium and 50 gl⁻¹ lead both as fluosilicates. At temperatures from 30 to 60°C and under potentiostatic control alloys containing 10–20% Cd were obtained with equivalent current densities of 2–5 A dm².

D. Eyre

Dr David Eyre graduated initially at UMIST in Manchester in Building Science but then joined Dr Gabe at Loughborough University to work first on A.C. anodizing (as part of a postgraduate course in Materials Protection) and then alloy electrodeposition. He is now a cathodic protection engineer with Spencer and Partners, London.

D. R. Eastham

Dr D. R. Eastham obtained his BSc and PhD in the Department of Metallurgy at Nottingham University, where he worked on the electrodeposition of nickel iron alloys. His early industrial experience was with Plessey on the etching and forming of aluminium foil for electrolytic capacitors. He is now Manager of the Special Projects Department at Glacier Metal where he is responsible for all research and development on metal finishing of plain bearings, and for materials testing. He is a member of both the Institution of Metallurgists, and the Institute of Metal Finishing, and is chairman of the conference technical committee for 1984–5.
