Friction and wear behaviours of Ti(C,O,N) dark decorative coatings
Munteanu, D.; Gabor, C.; Constantin, D. G.; Varga, B.; Adochite, R.; Andrei, O. C.; Chappé, J. M.; Cunha, L.; Moura, C.; Vaz, F.Reactive magnetron sputtering was used to obtain dark Ti(C,O,N) decorative coatings onto high speed steel. From a crystallographic point of view, depending by the amount of (N+O) mixture, the obtained films could be divided in two major regions: the first one with a predominant fcc crystallographic structure (for low amounts of (N+O)), and the second one containing films with amorphous structures. The best resu...
Structural and optical properties of Ag : TiO2 nanocomposite films prepared by ...
Adochite, R.; Torrell, M.; Cunha, L.; Alves, E.; Barradas, N. P.; Cavaleiro, A.; Rivière, J. P.; Eyidi, D.; Vaz, F.Three sets of nanocomposite films consisting of different atomic concentrations of Ag dispersed in a TiO2 dielectric matrix were deposited by DC reactive magnetron sputtering, and subjected to several thermal annealing experiments in vacuum, for temperatures ranging from 200 to 600 ºC. The main goal of the present study is to analyse the optical properties of the as-deposited and annealed films in order to clar...
