Abstract

PURPOSE:To soft-nitride iron material efficiently by using treating gas contg. ammonia gas, by separating and removing hydrogen with a diffusion cell composed of palladium alloy equipped at a gas softnitriding furnace. CONSTITUTION:In soft-nitriding of iron material with a gas contg. nitrogen gas as a main component, the hydrogen gas formed from ammonia is removed selectively by a diffusion cell using palladium alloy. For example, treating gas is charged to a radiant tube type furnace 10, and ammonia is added through a pipe line 9. The inside of the furnace is heated by means of a pipe 11 which is heated by the combustion of a burner 12, so that iron parts arranged on a chain conveyer 6 which is driven by rollers 3 are softnitrided. Then the gas in the furnace is sucked by driving a vacuum pump 20 through a vent hole 15, and the gas is discharged after hydrogen is absorbed by a diffusion cell 16 made by piling palladium alloy foil. The captured hydrogen gas may be supplied to the burner 12 so as to burned. It is also possible to soft-nitride continuously the iron material brazed in a furnace.
