Abstract

Fretting degradation of self-mated quenched and tempered steel was studied by varying loading conditions via imposed tangential displacement amplitude in oil-lubricated flat-on-flat contact. Detailed microscopic characterization showed the effects of tangential loading and the presence of oil at the interface on (sub)surface damage. A thin, cracked carbonaceous layer, arising from oil decomposition, was detected at adhesion spots in the mixed slip-stick regime. Furthermore, surface oxidation was noticed at the highest imposed displacement amplitude of 45 µm in gross slip, despite the presence of oil. Based on the crack analysis, a substantial increase in crack size was observed by transitioning from mixed slip-stick to gross slip.

油润滑下大平面接触的微动退化：位移幅值的影响

通过施加切向位移幅值，研究了不同加载条件下自调质钢在油润滑平对平接触中的微动退化。详细的微观表征显示了切向载荷和界面处油的存在对（亚）表面损伤的影响。在混合滑粘状态下的附着点处发现了一层由油分解产生的薄而开裂的碳质层。此外，尽管存在油，但在总滑移的最大施加位移振幅为45 µm时，仍注意到表面氧化。裂纹分析表明，由混合滑移向总滑移过渡，裂纹尺寸显著增大。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
