在本研究中，研究了通过等离子渗氮获得的改性层的磨损和腐蚀性能。通过将含碳气体添加到气体混合物中来实现等离子体氮化。使用不同的气体混合物在 500°C 下进行等离子渗氮处理 4 小时。虽然通过在 N2-H2 气体混合物中应用等离子体渗氮来产生单层改性层，但在 N2-H2 中添加含碳气体后，在表面上获得了双层结构。内层为碳固溶相(γC)，外层为氮固溶相(γN)。结果表明，双层结构改善了 316L 不锈钢的磨损性能，且对耐腐蚀性没有任何不利影响。
In the present study, the wear and corrosion properties of the modified layer that was obtained as a result of plasma nitriding were investigated. The plasma nitriding was achieved by adding carbon containing gas into the gas mixture. Plasma nitriding treatments were performed with different gas mixtures at 500°C for 4 h. While a single modified layer was produced through the application of plasma nitriding into a gas mixture of N2–H2, a dual layer structure was attained on the surface after adding carbon containing gas into N2–H2. The inner layer was in a carbon solid solution phase (γC) and the outer layer was in a nitrogen solid solution phase (γN). It was observed that the dual layer structure improved the wear properties of the 316L stainless steel without having any adverse effect on the corrosion resistance.
