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 μm 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 .
