| 摘 要： | 利用等离子表面改性技术在Ti6Al4V合金基体上制备Mo渗镀复合改性层,考察改性层组织结构,利用微动摩擦学试验机并结合电化学噪声技术对比研究基材及改性层在0.5 mol/L NaCl溶液中的腐蚀-微动摩擦学行为,对腐蚀-摩擦过程中的噪声参数进行分析.结果表明:纯Mo改性层能够明显改善钛合金的耐磨和减摩特性;同时提高了合金在0.5 mol/L NaCl溶液中的自腐蚀电位及降低了腐蚀电流,改善了合金表面的腐蚀-摩擦学性能.

| Abstract: | The Mo surface modified layer on Ti6Al4V substrate is obtained by plasma surface alloying. The structure and composition of the Mo surface modified layer are investigated by X-ray diffraction (XRD) and glow discharge optical emission spectroscopy. The duplex Mo modified layer contains a pure Mo coating on subsurface and diffusion layers between the subsurface and substrate. XRD analysis of the Mo modified layer reveals that a Mo phase exists in the modified layer with <110> and <211> orientations in the subsurface. Corrosion-wear behaviors of Ti6Al4V substrate and Mo modified Ti6Al4V alloy sliding against corundum are investigated with the wear-electrochemical noise technique in a 0.5mol/L NaCl solution. Results indicate that the Mo modified layer improves the antiwear and friction reduction properties of Ti6Al4V. Moreover, the Mo modified layer improves self-corroding electric potentials and decrease the current of Ti6Al4V. The Mo modified layer can improve the corrosion-wear behavior of Ti6Al4V. |
