    摘要： A composite diffusion type nitriding method and a composite diffusion type nitriding apparatus of the present invention are effectively used for nitriding various materials, such as machine parts, as well as a material which is difficult for nitriding by a conventional method. The composite diffusion nitriding apparatus is formed of a container filled with solid granular materials, a furnace for housing the container therein, a nitriding gas introduction path for introducing the nitriding gas into the container, and an exhausting path for exhausting the gas from the container. In the method, the material to be nitrided is placed in the solid granular materials, and the nitriding gas is supplied to flow through the solid granular materials to thereby nitride the material.
