Abstract
The Ti/C modified layers were prepared on Ti–6Al–4V alloy by double glow plasma surface alloying technique. The microstructure and composition of the modified layers were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM). The bonding strength, micro-hardness and friction performance of the modified layers were examined by the scratch tester, micro-hardness tester, reciprocating wear tester, and white light interferometer. The results show that both of the microstructure and properties of the Ti/C modified layer get the remarkable effects when the temperature reaches 910∘C. Belonging to metallurgical bonding with the substrate, the modified layer possesses a continuous, compact and uniform packet-like particle structure. Compared with the Ti–6Al–4V substrate, the surface micro-hardness and wear resistance of Ti/C modified layer are significantly improved.
