“…The nanofriction mapping in conjunction with the nanowear mapping can provide valuable information regarding the operating parameter dependence of nanoscale friction and wear. Tambe & Bhushan (2005d ) have demonstrated the effectiveness and utility of these techniques when used in tandem while studying the phase transformation-related reduction in friction force for DLC. …”

Friction and wear are part and parcel of all walks of life, and for interfaces that are in close or near contact, tribology and mechanics are supremely important. They can critically influence the efficient functioning of devices and components. Nanoscale friction force follows a complex nonlinear dependence on multiple, often interdependent, interfacial and material properties. Various studies indicate that nanoscale devices may behave in ways that cannot be predicted from their larger counterparts. Nanoscale friction and wear mapping can help identify some 'sweet spots' that would give ultralow friction and near-zero wear. Mapping nanoscale friction and wear as a function of operating conditions and interface properties is a valuable tool and has the potential to impact the very way in which we design and select materials for nanotechnology applications.

“…However, according to the slow decrease in the ν C=O intensity, the strong adhesion of the organic coating on R- . This result may be explained by the addition of PMMA which is used for a suitable label adhesion [25][26][27]. The suggestion about the nature of the contact in the second stage is supported by the observation of lower friction values on hot-end coated glass bottles [1,28] or SnO 2 -coated flat glass when surfaces are 20 contaminated with organic residues [28,29].…”

Ab s t r a c tThe stabilization of organic coatings by tin dioxide resulting in glass bottle lubrication was investigated on flat glass. The anchoring function of SnO 2 was assessed for a mixture of polyethylene and polymethylmethacrylate. Friction tests in air confirm the SnO 2 anchoring property with the maintaining of the lubricant effect due to the polymer over large sliding distances. The persistence of the polymethylmethacrylate stretching band ν C=O on significant sliding distances in infrared microscopy experiments shows that the polymer coating stabilization results from the strong adhesion of the polymer on SnO 2 . The impact of roughness and surface chemistry on the stabilization of the polymer coating was tested. The 2 suppression of the lubricant effect by surface chemistry alteration or by roughness modification of SnO 2 suggests that roughness and surface chemistry of SnO 2 are both necessary for lubrication.

“…Wear on the coating leads to a sudden rise in capillary forces (stiction) and friction, and results in the failure of the micromirror. Polymer coatings like polydimethylsiloxane (PDMS) and polymethylmethacrylate (PMMA) and perfluoropolyether (PFPE) [82] are under investigation as potential candidates in MEMS/NEMS devices (Table 27.4). PFPE is a commonly used lubricant in magnetic disk drive industry to reduce friction and wear at the head-disk interface [82].…”

Micro-/Nano-electromechanical systems (MEMS/NEMS) are future devices that have a spectrum of applications ranging from rocket technology to biological sciences. Although MEMS devices are known for over two decades, very few categories of them are used in commercially applications due to their poor reliability. Tribological phenomena like stiction, friction, and wear are major issues affecting the reliability of contact MEMS/NEMS devices and micromotors, microgears, nanosliders, etc., are some examples in which reliability is greatly hampered by such dissipation processes. In recent years, lot of research was dedicated for improving the reliability of MEMS/NEMS through lab scale tribological studies e.g., nanotribological studies. Similar tribological studies were earlier carried out on components like magnetic storage devices, electrical connectors, etc., and were successfully tackled. Present chapter is an overview of the research done over the years to understand the phenomena like stiction, friction and wear in such devices. This chapter addresses the variety of tribological problems associated with MEMS/NEMS, tribological characterization through lab scale and in-situ techniques, and various solutions that are used for improving the reliability of such devices with respect to tribological problems.
