Electrolytic Cutting of Metals
- Columbia Univ., New York, NY (United States)
The research reported herewith describes a method suitable for cutting cylindrical shaped specimens electrolytically for the primary purpose of securing metallographic specimens of irradiated metals and alloys. The principles involved, and the cell conditions and cathode design established, are directly applicable to general cutting problems where conventional machine methods are inappropriately suited. Little effort was made to investigate cell conditions best suited to produce either an electrolytically polished cut surface or even the best possible smoothness of cut surface. Rather, attention was directed mainly to the most significant variable — cathode design — in an attempt to produce a cut having flat-cut surfaces with little undercutting, and in general one comparable in this regard to that secured by conventional cutting methods. This was achieved. Data are given on the quality of cut secured on a low carbon steel specimen anode as a function of five different cathode assemblies. Of the five designs, the cathode-auxiliary anode assembly produced the best cut. This cathode assembly is described in detail. Suggestions are advanced relative to possible modifications of the cathode-auxiliary anode assembly to enable shapes of unsymmetrical cross-sections to be successfully cut.
