摘要： The invention relates to a device for generating a cold plasma in a vacuum chamber and to the use of said device for thermo-chemical processing. The device includes a cathode (1) with hollow cavities (1a) for confining the plasma. Means (2) are provided about each hollow cavity (1a), and said means are capable of generating a magnetic field that forces the electrons to revolve about the field lines, the body of the cathode (1) interacting with a member (3) that allows for a flow of coolant for extracting the calories generated by the intense ionic bombarding at each one of said hollow cavities (1a).

摘要： The invention relates to a molten-salt bath for nitriding mechanical steel parts, essentially consisting of the following (the contents being expressed in wt %): 25 to 60 wt % of alkali-metal chlorides; 10 to 40 wt % of alkali-metal carbonates; 20 to 50 wt % of alkali-metal cyanates; and a maximum of 3 wt % of cyanide ions (formed during the use of the bath), wherein the total of the contents is 100 wt %. Preferably, the bath contains: 25 to 30 wt % of sodium cyanate; 25 to 30 wt % of sodium carbonate and lithium carbonate; 40 to 50 wt % of potassium chlorides; and a maximum of 3 wt % of cyanide ions (formed during the use of the bath), the total of the contents being 100 wt %.
