ABSTRACT:
An electric current is passed through an electrolyte having a neutral pH, between an inert tool-electrode and the alloy which is to be machined to the shape of the tool-electrode. The electrolyte contains fluoride and/or fluoborate ions as well as complexing ions both for the carbide-phase metal or metals of the alloy and for the metallic-phase metal or metals of the alloy.
