i6Al4V表面Mo-N改性层在人工体液及干摩擦条件下磨损性能的研究

he certain thickness and compact Mo –N surface modified layer on Ti6Al4V substrate was prepared by the plasma surface alloying technology. The structure and composition of the Mo –N surface modified layer were investigated by X - ray diffraction (XRD) and glow discharge optical emission spectroscopy (GDOES). The properties of wear at an ambient and in Hank’s simulating physiological solution of the Mo –N modified layer was investigated and compared with that of Ti6Al4V substrate material. Results show that Mo –N modified layer has much better friction-reducing and anti-wear ability in Hank’s simulating physiological solution, while it has poor friction-reducing and better anti-wear ability in dry condition.
