13. Transporte atômico e reação química em nanoestruturas TiN e TiN/Ti em aço nitretado a plasma
The use of cutting tools in progressively more severe conditions in the metal-mechanics industry and the requirement to increase tool life against friction, wear and high temperature corrosion made of surface treatments an important protection method. One of the most modern treatments is the so-called duplex, that consists of plasma nitriding and deposition

14. Biomaterials : hydroxyapatite deposition study via polymeric process on cp Ti surfaces modified by laser beam / Biomateriais : estudo da deposição de hidroxiapatita por via polimerica sobre superficies de Ti cp modificado por feixe de laser
The biomaterials area has been focused on the development of synthetic or artificial materials that have similar properties to the human bone tissue. Among the diverse alternatives, one of the most used is the metallic substrate coated with bioceramics. By this technique it is possible to combine biocompatibilty, mechanical properties and corrosion resistanc

16. Deposição de revestimentos compositos metal-ceramico WC-Co por fusão a laser : avaliação da resistencia ao desgaste e a corrosão
In the present work the laser c1adding process was used to produce WC-Co composite coatings with varied fractions of WC. The AISI 1045 steel was used as substrate. The coatings were produced afier severa! tests, which have permitted the determination of optimum operational parameters. The characterization ofthe coatings was performed by optic microscopy, sca

17. Study of the Ti-6Al-4V/TiO2 interface by scannig electron microscopy. / Estudo da interface Ti-6Al-4V/TiO2 por microscopia eletrônica de varredura.
Ti-6Al-4V alloy has been used with some success as biomaterial with applications in the field of dentistry and orthopaedics. The features with make the Ti-6Al-4V alloy such an interesting material are its good corrosion resistance in the biological environment, combined with an excellent degree of biocompatibility. The long-term biological effects of the slo
