| Zusammenfassung: | 13 Disclosed is a carburization heat treatment method including carburizing a workpiece at a relatively low temperature within a temperature range of A˜Ausing a vacuum carburizing furnace and then performing quenching using a high-pressure gas, in which the workpiece is made of typical carburizing alloy steel having a carbon content of about 0.10˜0.35 wt %. This method can be applied to carburization heat treatment of a steel workpiece sensitive to heat deformation, such as an annulus gear, in lieu of a conventional gas carburization method using plug quenching. |
