Advanced surface characterization of silver nanocluster segregation in Ag–TiCN bioactive coatings by RBS, GDOES, and ARXPS
(SpringerLink, 2013)
Surface modification by means of wear protective and antibacterial coatings represents, nowadays, a crucial challenge in the biomaterials field in order to enhance the lifetime of bio-devices. It is possible to tailor the ...

Surface characterization of Ti-Si-C-ON coatings for orthopedic devices: XPS and Raman spectroscopy
(ScienceDirect, 2011-01)
Ti–Si–C–ON films were deposited by DC reactive magnetron sputtering and their chemical properties, biofilm formation and toxicity were characterized. Based on the films composition three different growth regimes were ...

Towards nanometric resolution in multilayer depth profiling: a comparative study of RBS, SIMS, XPS and GDOES
(SpringerLink, 2010-01-09)
An increasing amount of effort is currently being directed towards the development of new functionalized nanostructured materials (i.e., multilayers and nanocomposites). Using an appropriate combination of composition and ...

Improving the oxidation resistance of AlCrN coatings by tailoring chromium out-diffusion
(ScienceDirect, 2010-11)
In this work, we have studied the improvement on the oxidation resistance of AlCrN-based coatings by adding a subsurface titanium nitride barrier layer. Since oxidation is interrelated with the inward diffusion of oxygen ...

Comparative depth-profiling analysis of nanometer-metal multilayers by ion-probing techniques
(ScienceDirect, 2009-04)
We examine here the depth resolution (interface width) in elemental analysis and depth profiling of complex layer systems of three ion-probing techniques, each of which has pros and cons: • Rutherford backscattering ...
