Enhancement of Cu Nanoparticles Dispersion in Nanolubricants by Magnetron Sputtering Deposition and Its Influence on the Tribological Behavior
Autor: M. Assolin Correa, D. F. Franceschini, Marinalva Ferreira Trajano, E.F. Silva, Salete Martins Alves, Felipe Bohn
Publikováno v: Journal of Tribology. 143
We investigated the chemical, physical, and tribological properties of nanolubricants consisting of epoxidized sunflower oil with Cu nanoparticles as additive. These latter are produced by magnetron sputtering at distinct current levels in the deposi

Growth kinetics and relationship between structure and mechanical properties of a-C(N):H films deposited in acetylene–nitrogen atmospheres
Autor: F. L. Freire, Luiz G. Jacobsohn, Gino Mariotto, D. F. Franceschini, M. M. Lacerda
Publikováno v: Scopus-Elsevier
Amorphous hydrogenated carbon–nitrogen films, a-C(N):H, were deposited by plasma enhanced chemical vapor deposition using acetylene–nitrogen mixtures. Film composition and density were determined by means of ion beam techniques being the film mic

Carbon nitride thin films prepared by reactive sputtering: Elemental composition and structural characterization
Autor: Carlos A. Achete, F. L. Freire, Gino Mariotto, M. M. Lacerda, D. F. Franceschini
Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 15:1970-1975
Amorphous carbon nitride thin films (a-CNx) have been deposited onto Si (100) substrates by using a rf diode sputtering system. The films were deposited in reactive nitrogen-argon atmospheres. The partial pressure of nitrogen ranged from 0% to 100% a

Publikováno v: Scopus-Elsevier
Hard amorphous hydrogenated carbon-nitrogen films were obtained by PECVD of pure methylamine and methylamine-acetylene mixtures. The chemical composition of the films was determined by nuclear techniques, and their structure examined by infrared and
