摘 要：In this paper, we report the use of blowing nitrogen gas for the successful fabrication of a composite layer composed of Ti/Ti N on a substrate of commercially pure titanium（cp-2） using the friction stir processing technique. The prepared composite layer was characterized by X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray spectrometry. The maximum microhardness of the Ti/Ti N composite reached 1024 HV, which is 6.4 times higher than that of the titanium substrate. The results of wear test indicated that the Ti/Ti N composite layer possesses excellent abrasive and adhesive wear resistance because of the formation of the Ti N and its high hardness.
