Abstract
This invention relates to a method for forming a uniform, deep nitride layer on and in steel works at low cost, wherein a steel work is fluorided in heated condition in an atmosphere of a mixed gas composed of fluorine gas and inert gas and, then, nitrided in heated condition in an atmosphere of nitriding gas.
