摘　　要：目的利用高周波诱导加热技术在钛板表面进行碳化改性,并对其机械物理性能进行探讨。方法用扫描电子显微镜观察了碳化改性钛板的表面及断面形貌;用X射线衍射仪对表面碳化层的组成进行了分析;用维氏硬度仪检测渗碳层的硬度。结果碳化改性处理后在钛板表面形成了约3μm碳化钛层;碳化钛层硬度最高可达2 610HV。结论使用高周波诱导加热技术在钛板表面进行碳化改性,为其作为耐磨损性材料应用于齿科种植体领域提供了理论依据。Objective Carbide layer was formed on the surface of Ti by heating in hydrocarbon atmosphere （benzene C6 H6 ） at 1 000 ℃ using high frequency induction heating method. Physical and mechanical properties of carbide coated Ti were investigated to examine its potential as an abrasion-resistant implant material. Methods The morphology of the carburized surface was observed by scanning electron microscopy （SEM）. The constituents and phase structure of the carburized surface was determined by X-ray diffraction（XRD）. Abrasion-resistant of the carburized surface was evaluated using the Vickers hardness test and Martens scratch test. Results Carbide layer of about 3 vm thickness was observed on the cross section of specimens by SEM. The Vickers hardness of surface carbide was more than 2 000. Conclusion These results showed that the surface-carbide Ti would be suitable for abrasion-resistant implant material such as for an abutment part of dental implant.
