“…[15] Perhaps the fluctuating profiles indicate that the film was partially delaminated by ploughing or was peeled off during S testing. [11,16] The S and final-scan profiles of f-GTST 15% and f-GTST 20% are better and shallower than the S and final-scan profiles of f-GTST 10% (see Figure 2c and 2d), indicating better layer structures and mechanical properties (H, E and S resistance) due to an adequate fraction of TTB in the films and the formation of the desirable microstructure. For both films, there are very few seriously abrupt changes in the S and the final-scan profiles, implying that the films did not peel off during S ramping.…”

“…The procedure was similar to that presented in detail elsewhere. [11] Before scratching, an initial surface profile of the samples was detected by pre-scanning the surface with the indenter under a low load of 100 mN. Depths of scratches with increasing scratch length were measured in-situ by profiling the surface of the film before, during and after the scratch test, resulting in a total length (pre-scan track) of 700 mm for the test while the scratch length (scratch scan) was 600 mm as applied to all f-MST i% .…”

Summary: Based on silsesquioxanes (SSO) derived from the hydrolytic condensation of [3-(glacildoxy)propyl]trimethoxysilane (GPMS), 20 wt-% tetraethoxysilane (TEOS) and titanium tetrabutoxide (TTB), two-layer SSO films were prepared for nanoindentation and nanoscratch tests. The tests were carried out to study the influence of different amounts of TTB in the two-layer hybrid films on hardness (H), elastic modulus (E) and scratch (S) testing profiles. The H profiles of the modified films showed two kinds of H corresponding to the two-layer structure. In the S testing profiles, all final-scan profiles did not absolutely coincide or overlap with the firstscan profiles. All S profiles revealed a fluctuanting characteristic and all S profiles can be divided into two regions in the horizontal displacement, because of the two-layer structure. The film containing an adequate amount of TTB (20 wt-%) was found to possess the largest H and E, as well as the best S resistance.

“…In the literature, although the load-dependent friction behaviors during nanoscratch tests have been reported for different materials [55][56], influences of indenter type on this load-dependent friction have been scarcely investigated. The present study shows the friction-load dependency is significantly affected by the indenter type and qualitative explanations for this indenter geometrical effect are given based on certain theories and assumptions; however, further studies involving quantitative analysis of the geometrical effects on scratching friction are warranted.…”

In this work we study the indenter geometrical effects on the nanoindentation and scratch behaviors of polymers (epoxy resin and its based nanocomposites) through both experimental and numerical approaches. Two different types of indenter commonly used in nanoindentation tests, Berkovich (i.e. three-sided pyramid-shaped) and conical-shaped, are studied. An indenter (tip) geometry reconstruction procedure is presented and the results are input into finite element models to better understand the mechanisms of the geometrical effects on nanoindentation. Originally, the effect of indenter geometry on nanoscratch behavior is also investigated experimentally. Overall, our results show that the corrected Oliver and Pharr's method is applicable to nanoindentation of polymeric surfaces and the indenter geometry plays significant roles in both the nanoindentation and nanoscratch tests. The conical-shaped indenter provides slightly overestimated mechanical parameters for the polymers tested due to the material pile-up. Therefore, for nanoindentation and scratch tests, the type of indenter should always be mentioned and comparisons between tests using different types of indenter should be taken with caution.

“…H/E can provide important information on the mechanical resistance of the material. The relative high value of H/E ratio reveals the high elastic deformation during contact, making it an excellent candidate for applications where both wear resistance and elasticity are required [8]. It has been found that the max load, 1)d r /d m , hardness, modulus, and H/E of GT35 were highest, followed by 9Cr18 and 40CrNiMo.…”

Nanoindentation and nanoscratch tests were performed for titanium nitride (TiN) coatings on different tool steel substrates to investigate the indentation/scratch induced deformation behavior of the coatings and the adhesion of the coating-substrate interfaces and their tribological property. In this work, TiN coatings with a thickness of about 500 nm were grown on GT35, 9Cr18 and 40CrNiMo steels using vacuum magnetic-filtering arc plasma deposition. In the nanoindentation tests, the hardness and modulus curves for TiN/GT35 reduced the slowest around the film thickness 500 nm with the increase of indentation depth, followed by TiN/9Cr18 and TiN/40CrNiMo. Improving adhesion properties of coating and substrate can decrease the differences of internal stress field. The scratch tests showed that the scratch response was controlled by plastic deformation in the substrate. The substrate plays an important role in determining the mechanical properties and wear resistance of such coatings. TiN/GT35 exhibited the best load-carrying capacity and scratch/wear resistance. As a consequence, GT35 is the best substrate for TiN coatings of the substrate materials tested.
