ABSTRACT:
A process for thermochemical treatment of metals with accurate control of the treatment temperature in a furnace having a structure similar to that of a classic furnace for thermal or thermochemical treatment in a rarified atmosphere, equipped with controlled heating means and, possibly cooling means, and comprising at least an anode and a cathode supporting the pieces to be treated. A cold plasma is generated around the pieces to be treated by applying between the anode and the cathode a pulse train at a relatively high frequency and of very short pulse width in relation to pulse repetition rate.
