Temperature dependence of single-asperity friction for a diamond on diamondlike carbon interface

Abstract

Evolution of coefficient of friction with deposition temperature in diamond like carbon thin films J. Appl. Phys. 112, 023525 (2012); 10.1063/1.4740082Temperature dependent properties of silicon containing diamondlike carbon films prepared by plasma source ion implantation A variable temperature, ultrahigh vacuum atomic force microscope ͑AFM͒ was used to characterize interfacial friction for a single-asperity diamond contact on a diamondlike carbon ͑DLC͒ substrate over a nominal substrate temperature range of 90 to 275 K. Calibrated friction force measurements were obtained by analyzing lateral force hysteresis loops as a function of normal force. For sufficiently large normal forces, the lateral force was proportional to the normal force, and a friction coefficient could be identified. varied approximately linearly with substrate temperature, with = 0.28 at T = 90 K and = 0.38 at 275 K. These results are compared to other recent variable temperature AFM friction measurements and to theoretical calculations based on the Tomlinson model. This comparison is obscured by large, experimentally uncontrolled temperature differences between the tip and the substrate which inevitably exist in conventional, variable temperature AFMs. A thermal model which can be used to quantitatively estimate these temperature differences is presented.

Frictional Dissipation in a Polymer Bilayer System

“…The sample temperature was measured using a thermocouple glued to the sample surface. Previously, it has been argued that if the scanning probe tip is not directly heated then the temperature at the sliding contact is rather undefined . Although this may be an issue for experiments performed under vacuum conditions, the experiments described here were performed under ambient atmospheric conditions, in which case the cantilever and tip are efficiently heated by thermal transport through the air. , …”

Femtosecond Laser-Induced Periodic Surface Structures in Titanium-Doped Diamond-like Nanocomposite Films: Effects of the Beam Polarization Rotation

“…The obtained friction values correlate with our previous results of the lower friction on the fs-laser-graphitized surface of the superhard carbon films during LFM imaging with a similar diamond-coated tip [ 47 ]. In addition, the values of the friction coefficient of a diamond tip on DLC film surface were reported to be μ ≈ 0.4 [ 48 ], considerably higher than the μ values in macroscopic friction measurements. The titanium doping of DLN films leads to higher friction coefficients in macroscopic measurements, increasing from 0.07 (for DLN films) to 0.29 (18%Ti-DLN film) due to the presence of TiC nanocrystals in the DLN matrix [ 11 ], with a similar tendency of the higher μ values for Ti-DLC films [ 49 ].…”

Nanoscale friction characteristics of hydrated montmorillonites using molecular dynamics

“…So far, theoretical, experimental, and simulation methods have been well developed in the field of nano-tribology. Atomic force microscopy (AFM) experiment has been performed to study the nanoscale friction behavior of graphene (Ye et al, 2016), polystyrenes (Bistac et al, 2008), diamondlike carbon (Dunckle et al, 2010), and muscovite mica (Erlandsson et al, 1988). Friction Force Microscopy (FFM) (Bhushan and Kulkarni, 1996), Optical Microscope (OM), and Scanning Electron Microscopy (SEM) have been applied to explore the friction effect of nanocomposites (Sirong et al, 2007).…”

“…In nanoscale tribology, many studies have been performed on the nanoscale friction behavior of graphene (Ye et al, 2016), carbon (Dunckle et al, 2010), muscovite mica (Erlandsson et al, 1988), nanocomposites (Sirong et al, 2007), etc. However, the effect of external factors, such as normal load, sliding velocity, etc., on the nanoscale friction behavior of clay minerals remains unknown.…”
