Title: Nitriding or soft nitriding method for steel
Inventor: ISHIHARA KATSUAKI
IPC: C23C8/26
Filed: 1993-04-08
Abstract: PURPOSE:To stably form nitride layers having excellent wear resistance, fatigue resistance, etc., by previously replacing the oxidized films on the surfaces of a stainless steel with fluorinated films, then subjecting these films to nitriding or soft nitriding. CONSTITUTION:A container 3 in which the stainless steel work 1 is charged is put into a heat treatment furnace 1 and thereafter this furnace is internally heated. Gaseous N2 is supplied from a tank 9 into the furnace and a fluoride soln. from a tank 5 is added to N2 and is supplied to the container 3 simultaneously with the temp. The fluoride soln. is decomposed at a high temp. and gaseous F is generated. This gas converts the oxidized films of Fe and Cr on the surfaces of the work 2 to the fluoride films. The temp. in the heat treatment furnace is gradually lowered by a circulating gas 14 which is passed through a cooler 7. The work 2 is taken out of the container 3 when the temp. falls down to <=200 deg.C. The work is then put into a nitriding treatment furnace and is heated to 570 to 600 deg.C in an atmosphere of NH3, NH3+RX or NH3+N2+CO2, etc. The fluoride films are reduced by the gaseous H2 generated by cracking of the NH3, by which the active surfaces of the stainless steel are exposed. These surfaces are nitrided by the gaseous N2 by cracking of the NH3 and the hard nitride layers of the Fe and the Cr are thus formed.
