Abstract
In order to shorten the waiting times until the equilibrium between cyanate and cyanide is established and to limit the use of substances and products containing cyanide for nitrocarburizing in salt melts, melts containing only cyanate and optionally carbonate are electrolyzed at a current density of 4 to 100 A/dm.sup.2 of electrode area to form an advantageous cyanide content of 1 to 5 wt. %.
