摘要: 利用等离子表面合金化技术在Ti6Al4V合金基体上制备渗Mo改性层,并与Ti6Al4V基材对比考察在05 mol/L HCl溶液中的电化学腐蚀性能及在沸腾的37%HCl中的化学腐蚀性能.结果表明,与基材相比Mo改性层在05 mol/L HCl溶液中的自腐蚀电位提高,腐蚀速率增大;在37%HCl中腐蚀速率明显降低.

Abstract:The Mo surface modified layer on Ti6Al4V substrate was obtained by the plasma surface alloying technique.The structure and composition of the Mo surface modified layer were investigated by X-ray diffraction (XRD) and glow discharge optical emission spectroscopy (GDOES).The duplex Mo modified layer contains a pure Mo coating on subsurface and diffusion layers between the subsurface and substrate.The X- ray diffraction analysis of the Mo modified layer reveals that a Mo phase exists in the modified layer with〈110〉and 〈211〉orientations in the subsurface.The electrochemical corrosion behavior in 0.5 mol/L HCl solution of the Mo modified layer was investigated and compared with that of Ti6Al4V substrate material.The chemical corrosion behavior in boiling 37% HCl solution of the Mo modified layer was investigated and compared with that of Ti6Al4V substrate material.Results indicate that self-corroding electric potentials and corrosion rate of the Mo modified layer are higher than those of Ti6Al4V substrate in 0.5 mol/L HCl solution.Corrosion rate of the Mo modified layer is lower than that of Ti6Al4V substrate material in 37% HCl.
