摘　　要：采用离子渗氮技术对TD3合金表面进行离子渗氮处理,采用金相显微镜、XRD,对渗氮层的组织形貌、物相结构进行观察分析;用显微硬度仪(维氏)测量渗氮层硬度,再用摩擦磨损试验机(往复式)进行常温干摩擦实验,对其耐磨性、磨痕形貌进行分析。结果表明:渗氮层深度可达80μm,渗氮层显微硬度最高可达1 190 HV,较基材硬度提高2.3倍以上,渗氮层含TiN、Ti_2N。渗氮试样磨痕深度与宽度减小,耐磨性能比基材也有显著提高。The surface of TD3 alloy was treated by ion nitriding technology. The microstructure and phase struc-ture composition of nitriding layer were analysed by metallographic microscopy and XRD . The hardness of the nitri-ding layer was measured by micro hardness tester. The dry friction experiment was made by the friction and wear test machine at room temperature. Based on i t , the wear resistance and morphology were analysed. The results show that the thickness of nitriding layer can reach 80 μm; the hardness of layer is up to 1 190 HV which increased more than 2. 3 times compared with substrate hardness; the nitriding layer contained TiN and Ti2N . The grinding track depth and width are reduced greatly and the wear resistance has been improved significantly than the substrate.
