The friction coefficients of different metal pairs are determined by the difference in the interatomic distance between each metal material under low load conditions. Here, eight types of metal pins were rubbed against Si(111) substrates that were covered with a native oxide film. Results showed that the friction coefficient increased when the interatomic distance of the metal approached the interatomic distance of SiO_2. A similar relationship was found between pairs of Ag/Cu/Ni and Au/Pt/Si(100). The combination of Au(111) and Si(111) exhibited clear friction anisotropy, which confirmed the above-mentioned relationship that was determined by interaction between the crystal structures.

不同金属对的摩擦系数由低载荷条件下每种金属材料之间原子间距离的差异决定。在此，将8种金属销与覆盖有自然氧化膜的Si（111）衬底摩擦。结果表明，当金属原子间距离接近SiO_2原子间距离时，摩擦系数增大。在Ag/Cu/Ni和Au/Pt/Si（100）对之间发现了类似的关系。Au（111）和Si（111）的组合表现出明显的摩擦各向异性，这证实了由晶体结构之间的相互作用确定的上述关系。
