Structural investigation by the Rietveld method of sputtered tungsten carbide thin films

Autor: E. Raekelboom, C. Legrand-Buscema, Karima Abdelouahdi

Publikováno v: Thin Solid Films. 517:1555-1558

Thin films of tungsten carbides deposited by reactive radio-frequency sputtering were investigated by X-ray diffraction using the Rietveld method. Two films were selected for the structural refinement. One was biased, the other unbiased. The unbiased

Friction properties of ion implanted Al2O3 ceramic

Autor: S. Coindeau, Jacek Jagielski, Z. Librant, P. Aubert, A. Piatkowska, C. Legrand-Buscema

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 206:1097-1100

The possibility of the use of ion implantation for reduction of friction coefficient of alumina has been studied. Two different approaches were used: formation of thin soft layer via noble gas irradiation and doping of surface layer via implantation

Publikováno v: Vacuum. 70:147-152

The effects of high dose nitrogen implantation into aluminum on phase structure and mechanical properties were studied by using Rutherford backscattering (RBS), scanning electron microscopy (SEM), atomic force microscopy (AFM), nanoindentation and fr

In the presented work we examined two methods of friction reduction of alumina samples; (i) formation of thin surface layer of reduced hardness (to take advantage of Tabor and Bowden concept of adhesive friction in layered materials) and (ii) introdu
