Title: Hydrogen infiltration prevention type vacuum hardening method and work production method using the same
Inventor: UEJIMA YASUTSUGU
IPC: C23C8/22
Filed: 2016-12-07
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum carburization method which does not generate hydrogen brittleness while using hydrocarbon gas as a carbon source.SOLUTION: A hydrogen infiltration prevention type vacuum hardening method: detects a reference hydrogen concentration corresponding to a reference gas amount allowing just enough carbon to attach to a work in an early stage of injecting hydrocarbon gas into a furnace; and sets a target hydrogen concentration on the basis of the reference hydrogen concentration. In a succeeding process, an introduction amount of hydrocarbon gas is controlled in a manner that keeps a hydrogen concentration inside a treatment furnace in a predetermined range not exceeding the target hydrogen concentration while continuously detecting the hydrogen concentration inside the treatment furnace. The target hydrogen concentration is, for example, a value lower than the reference hydrogen concentration. Because hydrogen generated through decomposition of the hydrocarbon gas is promptly removed, a work can be prevented from hydrogen infiltration. Thus, the hydrogen infiltration prevention type vacuum hardening method can prevent the work W from hydrogen brittleness by curbing generation of holes attributable to hydrogen while using a conventional vacuum carburization facility. Also, the hydrogen infiltration prevention type vacuum hardening method can be applied to carbonitriding and vacuum nitriding.SELECTED DRAWING: Figure 4
