Bismuth oxide (Bi2O3) coatings and composite containing this have been studied due to their potential applications in gas sensing, optoelectronics, photocatalysis, even tribology. Two parametric models based on chemical features proposed with the aim of predicting lubricity response oxides. However, such predict contradictory values coefficient friction (COF) for Bi2O3. In study, we deposited B...

I Abstract The present thesis focuses on carbon-based thin films prepared by high power impulse magnetron sputtering (HiPIMS) and direct current magnetron sputtering (DCMS). Carbon nitride (CN x : 0 < x < 0.20) as well as carbon fluoride (CF x : 0.04 < x < 0.35) thin films were synthesized in an industrial deposition chamber by reactive magnetron sputtering of graphite in Ne/N 2 , Ar/N 2 , Kr/N...

Variable filters are key components for compact spectral imagers. In this paper, we present a method the fabrication of linearly variable based on Bühler HELIOS machine (plasma assisted reactive magnetron sputtering). These obtained by producing variation thickness all layers coating, using adapted masks placed in between sputtering targets low and high refractive index materials substrates. ba...
