Abstract
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 100 0 Pa, 773 K, for 2 h. The influence of the hole dimensions on the temp erature uniformity was investigated. This work is important for the pl asma nitriding of workpieces with complex geometrical shapes, such as gearing, crankshafts, dies, and injection nozzles.
