摘要:
采用双层辉光离子渗金属技术，在T10钢表面进行渗钛，研究了渗钛层的显微组织和摩擦磨损性能。利用超景深三维显微系统、X射线衍射仪、显微硬度计、能谱仪等分别对渗钛层的组织、相结构、硬度及元素的浓度分布进行检测和分析，用MMW1万能摩擦磨损试验机研究了渗层的摩擦磨损性能。结果表明：T10钢双辉渗钛后可在表面形成均匀、致密且与基体结合良好的TiC层，渗钛层硬度达到1 100 HV0.01以上，且呈平缓的梯度下降。与未处理的T10钢相比，渗钛层的磨损率明显降低，耐磨性增强。

Abstract:
The titanized layer was prepared on the surface of T10 steel using a double glow plasma surface alloying technique, and its microstructure and tribological properties were studied. The microstructure, phases, microhardness and composition distribution of the titanized layer were characterized by metallographic photos OM(OM), Xray diffraction(XRD), microhardness tester, and energy disperisve spectrometer(EDS), respectively, The tribological properties were detected by MMW1 friction and wear tester. The results show that the TiC layer formed on the sample surface is homogeneous, dense, and metallurgically combines with the substrate. The microhardness of the titanized layer is up to 1 100 HV0.01, and gradually decreases with the depth. Compared with the asreceived substrate, the friction coefficient of the titanized layer is reduces, exhibiting excellent wear properties.
