“…In other words, the COF increases with the increase in misorientation of sliding direction from the <001> primary crystallographic orientation. These behaviors are in agreement with the results reported by Huang et al (2009) and Flom and Komanduri (2002). Tanaka and Oda (1973) studied sliding friction behavior of SC copper against hard sliders of copper and steel.…”

Investigation on the effects of crystallographic surface and sliding orientations of CMSX-4 single crystal Ni-base superalloy (SC) on the cyclic sliding friction (CSF) behavior against IN718 polycrystalline Ni-base superalloy (PC) has been carried out at room temperature and at 600• C. Tests have been conducted on three different surface orientations (crystallographic orientation of sliding surface) and two different sliding orientations (crystallographic orientation toward the sliding direction), in order to explore the anisotropic friction response of SC/PC sliding contact pair. A significant normal load depended anisotropic tribological behavior was observed. On a given contact surface orientation, a specific effect of sliding direction was also established. This anisotropic behavior was found to be significant and was independent of test temperature. Discussions were made on the above experimental results. It was suggested that both the stress and the deformation field near the contact area which are closely influenced by the anisotropic mechanical properties in longitudinal and transverse elastic moduli and in yield strength would play extrinsic roles there.

“…In other words, it is clear from these results that the deviation from the <001> principal crystallographic direction led to an increase in the frictional force for a fixed normal force. The behaviors are in agreement with the results reported by Huang et al (2009) and Flom and Komanduri (2002).…”

“…The non-centrosymmetric anisotropic friction were observed in aluminum crystals on a face with threefold symmetry (Flom and Komanduri, 2002) and in triglycine sulfate (Bluhm et al, 1995). The friction asymmetries were found in thin monomolecular layers with the known microstructures: in LangmuirBlodgett films on mica (Gourdon et al, 1997), in a lipid monolayer of mica (Liley et al, 1998), in polydiacetylene monolayer films (Carpick et al, 1999) and in monolayers of glycerol ester (Hisada and Knobler,Fig.…”

“…They suggested that friction anisotropy arises from the bulk mechanical properties of the crystals. Flom and Komanduri (2002) investigated the effect of crystal orientation and direction of sliding on friction and on wear tracks formed in single crystals under sliding a hard indenter. Anisotropy in friction and wear was observed in crystals of copper, aluminum, iron and cadmium.…”

Anisotropy and heterogeneity of friction and wear can result from anisotropic roughness of engineering surfaces and from anisotropic and heterogeneous microstructures present in many materials (wood, single crystals, ceramics, composites, layer-lattice materials, polymers, biomaterials, monomolecular layers). In sliding surfaces of some materials, kinematics of sliding initiates microstructural and frictional changes. This research deals with advanced constitutive models, which describe evolutions of frictional anisotropy and heterogeneity induced by the sliding kinematics. First-, second-and higher-order constitutive equations of friction are developed with respect to powers of a sliding path curvature. The first-order equation of the friction force has two independent variables: sliding velocity unit vector and its derivative. The second-and higher-order equations are polynomials with respect to odd order tensors composed by the sliding velocity unit vector and the derivative. In the equations, friction tensors of even orders describe anisotropy and inhomogeneity of friction and effects associated with the sliding kinematics. The sliding path curvature generates: (a) an additional resistance to sliding, (b) a constraint force normal to the sliding trajectory. The friction constitutive equations satisfy the axiom of objectivity. A condition of dissipated energy restricts the friction tensors and the radius of curvature. Examples illustrate friction descriptions.

“…Various authors who reported about such experiments [5][6][7][8][9][10] observed that for most annealed single-crystals, such as Cu, W, Fe, Al, or NiAl, distinct pile-up patterns occur only in certain directions around the indentation depending on the crystallographic orientation of the single-crystal [5][6][7][8][9][10]. Very detailed atomistic simulations about the incipient stages of nanoindentation in face centered cubic single crystals were recently conducted by Li et al [11] and Van Vliet et al [12].…”
