    摘要： The method of carburizing steel workpieces comprises loading workpieces to be carburized in a furnace and maintaining them in a carbon enriching atmosphere comprising carbon monoxide, hydrogen and nitrogen. The treatment comprises a first phase carried out at a temperature from 850.degree. C. to 1050.degree. C. followed by a second phase carried out at a temperature from 700.degree. C. to 950.degree. C. During the first phase an atmosphere is used having a carbon potential from about 1.1% to about 1.6% by weight and during the second phase the amount of nitrogen in the atmosphere is increased from two to thirty times so that the carbon potential for the second phase is at least about 0.5% by weight less than the carbon potential for the first phase.

    摘要： 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.

    摘要： Fuel, fertile material and/or absorber material containing particles for fuel and/or absorber elements in nuclear reactors are coated by a process comprising introducing thermally cleavable gases in the reaction space heated to above 1000.degree. C. of a fluidized bed unit with the help of a gas inlet nozzle cooled with a cooling medium and having an elongated inlet tube, decomposing the cleavable gases after leaving the nozzle, depositing the decomposition products on fuel, fertile material or absorber particles present in the fluidized bed and bringing these coated particles into fuel elements or absorber elements. The cooling medium is solely gaseous and only the portion of the inlet tube for the nozzle tips of the gas inlet nozzles within the axis are cooled and the heat flow penetrating from outside is reduced by heat insulation. An apparatus for carrying out the process is also described.

    摘要： To carbide coiled-coil tantalum or tantalum alloy filament without causing it to distort, the coiled-coil metal filament is supported in a firing container consisting essentially of carbon as the only container component which will react with tantalum. The interstices between individual coils of the coiled-coil filament are filled with finely divided carbon, preferably graphite. The container and filament are then heated in an atmosphere of carbon or carbon plus nitrogen as the only reactive gases under predetermined temperature conditions and for a predetermined period of time sufficient to convert the filament to stoichiometric carbide.
