对1020钢和316不锈钢圆柱试样在常规直流等离子体渗氮（DCPN）和阴极笼式等离子体渗氮（CCPN）条件下进行了渗氮处理。1020和316不锈钢试样分别在773 K和360 Pa下处理3 h和5 h。采用光学显微镜、X射线衍射仪和显微硬度计对样品进行了表征。经DCPN氮化处理的试样在暴露于等离子体的表面均出现腐蚀环。相比之下，在CCPN氮化的样品中，侵蚀环被完全消除，氮化层中存在的不同阶段的机械性能没有损失。(c)2006 Elsevier B.V.保留所有权利。
Cylindrical samples of 1020 steel and 316 stainless steel were nitrided under the conditions by conventional dc plasma nitriding (DCPN) and by a new technique denominate cathodic cage plasma nitriding (CCPN). The 1020 and 316 stainless steel samples were treated during 3 h and 5 h, respectively, in 773 K and 360 Pa. The samples were characterized by optical microscopy, X-ray diffraction and microhardness testing. All the samples nitrided by DCPN process presented erosion rings on the surface exposed to the plasma. In comparison, in samples nitrided by CCPN, the erosion rings were completely eliminated, without loss of the mechanical properties in the different phases of existence in the nitrided layer.
