| Abstract: | Ramped load nanoscratch behaviors of titanium thin films with and without dendrimer mediation were extensively studied. By combining in situ investigation of scratch surface profiles and coefficients of friction curves, with ex situ microscopic (OM, AFM) and spectroscopic (AES) examinations of scratch tracks, different scratch failure modes were identified. An adhesive failure was found in the dendrimer-mediated films, whereas a cohesive failure was in the dendrimer-free samples. |
