Abstract
A heat treatment process, which uses a longitudinal heat treatment device to thermally treat the processed object in which the longitudinal heat treatment device comprises a reaction pipe comprised of two-layer pipe construction which is constituted of inner pipe and outer pipe, a first gas supply pipe and a second emission pipe which separately has an opening installed toward the inner side of the inner pipe, and a second gas supply pipe and a first emission pipe which separately has an opening between the inner pipe and the outer pipe; in which the heat treatment process comprises: a first process, which uses the first gas supply pipe and the first emission pipe to conduct the treatment gas flowing from the inner side of the reaction pipe toward its outer side during which the gas was heated and undergone membrane formation treatment on the surface of treated object under reduced pressure atmosphere; and a second process, which continues the first process and uses the second gas supply pipe and the second emission pipe to conduct the treatment gas flowing from the outer side of the reaction pipe toward its inner side during which the gas was heated and undergone oxidation or diffusion treatment on the surface of the treated object under reduced pressure atmosphere.
