Copper, permalloy, cobalt, and silicon are the materials that have been widely utilised in magnetic devices. When the size of interest is down to the nanoscale, the inter-diffusion between certain materials becomes influential. This paper studies the nanoscale friction characteristics between frictional pairs with and without inter-diffusion properties through the atomic force microscope. The distinct evolution features of nanoscale friction force when inter-diffusion is involved are discovered experimentally, which is also confirmed through theoretical analysis. Firstly, through the thin film deposition method, four pairs of contact materials (Cu–Ni81Fe19, Si–Ni81Fe19, Cu–Co, Cu–Si) are designed for friction tests, in which diffusion occurs at the interface of Cu–Ni81Fe19 pair. Then, the effects of sliding velocity and loading force on the nano friction of each pair are measured. It is found that regardless of the diffusion phenomenon: (1) the adhesion force values exhibit a notable correlation to the values of the friction force; (2) the friction force in all four material pairs consistently increases with the growth of the normal loading force, although the growth rate may differ. In terms of the sliding velocity effect, the friction forces of immiscible materials (Si–Ni81Fe19, Cu–Co, and Cu–Si) are found to increase with the increasing sliding velocity. However, the friction force of Cu–Ni81Fe19, decreases with the increasing sliding velocity. Furthermore, a compositive friction model considering both the velocity and the normal force effect was proposed, which shows good agreement with the experimental results and explains the nano friction behaviour of both miscible and immiscible metals.

“…Moreover, the high-energy electron beam used in SEM may impact the interfacial frictional properties of 1D materials in several ways: (i) inducing changes in the sample's morphology, potentially deviating from its native state; 202 (ii) generating electrostatic attraction forces that interfere with precise friction force measurements; (iii) triggering chemical reactions, altering the interfacial composition and inuencing observed frictional behavior; 203,204 and (iv) inducing residual stress in 1D NWs being tested and altering the accuracy of the indirect measurement strategies. 192 In addition, the manipulation of 1D materials in SEM processes potential obstacles, including the impact of manipulator vibration 199,[205][206][207][208][209] and the preload 200 of the manipulation tip, both may affect the result accuracy.…”

“…While in the analytical method, the displacement function needs to be determined first, and then the unknown parameters need to be calculated according to the boundary conditions, whose process is complicated and is not conducive to engineering application. The use of the reciprocity theorem of work can simplify the solution process [16], and the results have high reliability and strong applicability. The theorem of reciprocity of work means that when two sets of generalized forces act on a linear elastic body, the work done by the first set of force on the displacement caused by the second set of force is equal to the work done by the second set of force on the displacement caused by the first set of force.…”

How to reduce the friction resistance between two planes is a difficult problem that has been studied in the field of tribology. Aiming at this problem, the concept of reducing the friction resistance by exciting the periodic change of normal force between the planes is proposed. A calculation model of the displacement amplitude distribution of the plate is established based on the principle of reciprocity of work, and the influence of the periodic change of normal force on sliding friction between the planes is studied. Additionally, an experimental device for analysis of friction between the planes under the periodic change of normal force is established. The calculation model of the plate’s displacement amplitude distribution considering the change frequency of normal force is verified and modified by experiments. The research results mainly show two aspects. On the one hand, the calculation model of the displacement amplitude distribution of the plate is in good agreement with the experimental results, which can effectively help to study the effect of periodic change of normal force on sliding friction between the planes. On the other hand, the change of amplitude and frequency of the normal force have an influence on the sliding friction between the planes. That is, the latter decreases with the increase of the former. The above conclusions have great reference significance for the study of vibration drag reduction in engineering production.
