Frictional Behavior of Micro/Nanotextured Surfaces Investigated by Atomic Force Microscope: A Review

Abstract

Tribological issues between friction pair are fundamental problems for minimized devices because of their higher surface-to-volume ratio. Micro/nanotexturing is an e®ective technique to reduce actual contact area between contact pair at the nanoscale. Micro/nanotexture made a great impact on the frictional behavior of textured surfaces. This paper summarizes the recent advancements in the¯eld of frictional behavior of micro/nanotextured surfaces, which are based on solid surface contact in atmosphere environment, especially focusing on the factors in°uencing the frictional behavior: Surface property, texturing density, texturing height, texturing structure and size of contact pair (atomic force microscope (AFM) tip) and texturing structures. Summarizing the e®ects of these factors on the frictional behavior is helpful for the understanding and designing of the surfaces in sliding micro/nanoelectromechanical systems (MEMS/NEMS). Controlling and reducing the friction force in moving mechanical systems is very important for the performance and reliability of nanosystems, which contribute to a sustainable future.Surf. Rev.

Micro/Nanoscale Tribological and Mechanical Investigation of the Articular Surfaces of Katydid Leg Joints: Potential for the Novel Bioinspired Lubrication Systems

“…In summary, various factors which affect frictional behavior of a micro/nanotextured surface at the nanoscale can be discussed in detail. For example, density of texture, size of contact area, and shape of texturing structure [14].…”

Surface Texture-Based Surface Treatments on Ti6Al4V Titanium Alloys for Tribological and Biological Applications: A Mini Review

“…Surface patterns on textured surfaces usually have regular distributing characteristics at nano- or micro-scales, therefore microscopic analysis is required. Scanning electron microscope (SEM), atomic force microscope (AFM) and laser scanning confocal microscope (LSCM) are often used to observe the geometrical characteristics of surface texture [ 82 , 83 , 84 ]. Additionally, some researchers have paid attention to the residual stresses in surface layers on the textured surfaces [ 85 , 86 ].…”

“…While under the negative effects of friction in normal applications, the service performance of Ti6Al4V engineering components would be decreased and then the lifecycle of the whole equipment might also be reduced [ 100 , 101 ]. Surface texture-based surface treatments developed by different scientists and engineers have provided promising approaches to overcome the relevant issues [ 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ,…”

Frictional effect of spherical convex textured rigid bodies sliding on smooth PDMS

“…Surface texturing has been considered as an effective method to improve the friction coefficient and wear rate of friction couples [2][3][4]. Huang et al [5] experimentally investigated the coupling effects of surface texture and surface wettability on contact lubrication of elastomers, it is found that the friction behavior of the surface texture is quite different under different lubrication conditions.…”
