中文摘要:
      为完善钛合金微动摩擦磨损特性数据,以磨损颗粒在不同位移幅值下于界面间的运动分布为手段,研究不同运动分布下的微动行为和损伤机制。结果表明:位移幅值显著影响着磨损颗粒的运动分布。小位移下中心粘着撕裂形成的片状脱层沿垂直于微动的方向堆积成“脊”;中等位移下磨屑颗粒平铺于接触表面;较大位移下团簇状磨屑沿平行于微动的方向重新聚集成水平“脊”。磨屑在接触界面不同的运动分布导致磨损机制由粘着磨损,过渡到磨粒伴随轻微粘着,最终以磨粒伴随氧化磨损为主。
Distribution of the wear particles for TC4 alloy in fretting
英文关键词:TC4 alloy  fretting wear  wear particles  displacement amplitudes  distribution
英文摘要:
      To have a better understanding of fretting wear for titanium alloys, the effect of wear particles distribution on coefficient of friction, wear volume, surface topography and danage mechanisms at various displacement amplitudes was investigated. The test results showed that the displacement amplitude has a significant influence on the distribution of the fretting wear particles. The ‘flake-like’ delamination formed by the central adhesive teard was stacked into a ‘ridge’ in a direction perpendicular to the fretting at a relative low fretting-amplitude.At a medium amplitude,the debris particles were scattered on the contact surface.When the amplitude was even increased,‘cluster-like’ debris were accumulated into a ‘ridge’ paralleled to the direction of the fretting.The various distribution of the wear particles leads to the change in the wear mechanisms from the adhesion to abrasive with slight adhesion,and finally the adrasion accompanied the oxidative wear.
