Abstract: 816,409. Cementation. WINK, H., and HANF, H., [trading as ELINO INDUSTRIE-OFENBAU C. HANF & CO. Dec. 5, 1956 [Dec. 6, 1955], No. 37207/56. Class 72 [Also in Group XII] Steel articles are carburized, nitrided or carbonitrided by heating in a treatment furnace containing a static charge of gas, the pressure of which is alternately raised and lowered. As shown, a furnace having a treatment chamber 2 electrically heated by resistances 1, is connected to a chamber 4 which contains a piston 5. The treatment gas is passed through the chamber 4 and the pipe 3 into the chamber 2 and the gas pressure is caused to fluctuate by movement of the piston 5 in the cylinder 4. If the gas becomes exhausted before the treatment of articles in the chamber 2 is complete, a fresh charge of gas may be admitted through the inlet valve 6 displacing the spent gas through outlet valve 7. In a modification, the variations in pressure may be achieved by introducing the treatment gas under pressure through an inlet valve whilst an outlet valve is shut, after which the inlet valve is shut and the outlet valve is opened, the cycle is repeated as many times as is necessary to achieve the desired treatment.
