Question:
Where can I find some up-to-date information on various substitutes for cadmium and chromium? R.K.
Answer:
A series of four papers written by E.W. Brooman appeared in Metal Finishing: 98(4), 42, 2000; 98(6), 106, 2000; 98(7), 38, 2000; 98(8), 39, 2000. The first two papers deal with environmentally acceptable alternatives for cadmium. The last two papers deal with environmentally acceptable alternatives for hexavalent chromium. This series of papers gives much data and many references.
A paper in a somewhat less technical vain is by G. E. Shahin, "Plating & Surface Finishing," 85(8), 8, 1998. This paper discusses alloys of various types that are used as replacements for cadmium and chromium.
