A structural and mechanical analysis on PVD-grown (Ti,Al)N/Mo multilayers
Tavares, C. J.; Rebouta, L.; Alves, E.; Cavaleiro, A.; Goudeau, P.; Rivière, J. P.; Declemy, A.(Ti,Al)N/Mo multilayered hard coatings have been designed to fulfil future applications concerning wear-prevention on tool steels. They have been deposited by reactive dc magnetron sputtering on high-speed steel substrates with modulation periods between 6.5 and 8 nm. Experimental X-ray diffraction (XRD), Rutherford backscattering spectrometry (RBS) and computational modelling of those patterns has undergone to...
Characterisation of Ti1-xSixNy nanocomposite films
Vaz, F.; Rebouta, L.; Goudeau, P.; Pacaud, J.; Garem, H.; Rivière, J. P.; Cavaleiro, A.; Alves, E.Ti1-xSixNy films were synthesised by RF reactive sputtering from Ti and Si elemental targets, in an Ar/N2 gas mixture. XRD results revealed the development of a two-phase system, composed of a nanocrystalline f.c.c. TiN (phase 1: B1 NaCl type) and a second one (phase 2), where Si atoms replaced some of the Ti ones, inducing a structure that we may call a solid solution. An amorphous phase, supposed to be of sil...
