“…The interior of the groove is quite smooth, which implies ductile mode of deformation during the scratch process. [10,23] At higher magnification, numerous slip steps of shear bands have been observed along the banks on either side of the groove, as shown in Figure 3. At the entry and exit of the scratch (where the DOC is shallower than that in the middle of the scratch groove), only one set of shear bands, inclined at around 10 and 30 deg to the scratch direction and with a spacing of 300 to 500 nm, have been observed (Figure 3(a)).…”

“…[11,22,23] A single-point conical (90 deg included angle) diamond dressing tool is used as the scratch tool. The tool is held in a pendulum that is supported by two precision ball bearings housed in a steel fixture.…”

“…The principle of experimental scratch-testing technique has been described elsewhere [15,16]. The apparatus used in this study for the single-grit pendulum scratch test (developed at Michigan Technological University, Houghton, MI) [17] consists of a rigid platform on which the specimen fixture is mounted and includes translation capability for ease of specimen mounting and positioning ( Fig.…”

“…We used a newly-developed single-grit pendulum scratch technique to measure the dynamic abrasion due to sliding contact. This approach is employed because of its advantages over the traditional sliding scratch technique in characterizing the materials removal mechanisms [15][16][17][18]. In the following, the unique features of the experimental apparatus will be given, the experimental results on three TiAls that have potential application in diesel engines will be presented, and finally the analyses of the results with special respect to the material removal and energy dissipation will be given.…”

“…Once the observations and associated data has been achieved to distinguish between different features it can then be used to look at different levels of cutting, ploughing and rubbing experienced in a grinding. There has been a lot of work on SG analysis previous to this work where the material removal mechanisms were investigated from microscope analysis and acquired force signals (Hamed, 1977;Subhash et al, 2001;Wang and Subhash, 2002). This work looked at the different mechanics of grinding from different rake angles being presented during the scratch formation.…”
