摘要：

In the plasma nitriding process, the workpiece is uniformly covered by glow discharge and is heated by ionic and neutral species bombardment. In this study, AISI 304 stainless steel workpieces with cylindrical blind holes were plasma nitrided in an atmosphere of H-2-20N(2) at 1000 Pa, 773 K, for 2 h. The influence of the hole dimensions on the temperature uniformity was investigated. This work is important for the plasma nitriding of workpieces with complex geometrical shapes, such as gearing, crankshafts, dies, and injection nozzles.
