Ti₂AlNb合金等离子渗碳及其抗冲蚀性能的研究

详细信息

摘要: 通过双辉等离子渗金属技术对Ti₂AlNb合金进行等离子渗碳,采用扫描电镜、X射线分析和线扫描等手段来分析渗碳层的微观形貌、元素分布和表面相组成,并且利用冲蚀磨损试验来对比两者的抗冲蚀磨损性能。结果表明,等离子渗碳可以在基体表面形成一个大约30μm的渗碳层;基体显微硬度为393 HV0.1,渗碳层的硬度则达到979 HV0.1;Ti₂Al Nb合金抗冲蚀磨损能力在渗碳后有了明显提升。

Abstract: The carburized layer was engineered onto Ti₂AlNb orthorhombic alloy by a double glow discharge plasma technique.The microstructure,elements distribution and phase composition of the carburized layer were characterized by scanning electron microscope(SEM),X-ray diffraction(XRD) and energy dispersive spectrometer(EDS).The micro hardness of the carburized layer and the substrate were measured,and erosion resistance tests were carried out to test their erosion wear resistances.The results indicated that a carburized layer,about 30 μm-thick,is formed by double glow plasma carburizing.The micro hardness of the layer is 979 HV0.1 and the substrate is 393 HV0.1.The erosion wear resistance of Ti₂AlNb alloy carburized is significantly improved.
