我们研究了粘附力对由金 (Au) 和铁 (Fe) 组合组成的纳米带结构的摩擦性能的影响。在原子力显微镜摩擦实验过程中，相对湿度 (RH) 控制在 10%–80%。使用在Si样品上溅射Au和溅射Fe进行比较。纳米带表面表现出与Au和Fe不同的特征摩擦特性。纳米带的附着力与铁相当，并且纳米带的摩擦性能与相对湿度无关。然而，在法向载荷为零时，摩擦力是有限的，并且摩擦力随着法向载荷的增加而非线性增加。我们将讨论 Au 和 Fe 与纳米带之间不同趋势的原因。
We have investigated the effect of adhesion force on the frictional properties of a nanostripe structure composed of a combination of gold (Au) and iron (Fe). Relative humidity (RH) was controlled from 10%–80% during the friction experiment by atomic force microscopy. Au sputtered and Fe sputtered on Si samples were used for comparison. The nanostripe surface showed characteristic frictional property, which differed from that of Au and Fe. The adhesion force of nanostripe was comparable to that of Fe, and the frictional property of nanostripe was independent of RH. However, friction force is finite at the normal load of zero, and friction force non-linearly increased with increasing normal load. We will discuss the reason for the different trends between Au and Fe and nanostripe.
