“…2. This supports the fact that in the layers, titanium oxynitride TiN x O y phases with fcc structure grow in our experimental conditions [1,2,18,19]. The lattice parameter determined from the position of the (2 0 0) peak (Table 1) increases from 0.420 nm for the sample S1 up to 0.424 nm for the sample S4, which agrees with the lattice parameter of TiN [20].…”

“…Além disso, em anos recentes, diversas pesquisas têm sido conduzidas, principalmente devido a sua biocompatibilidade e a sensível modificação de suas propriedades, como fricção, absorção óptica, dureza, molhabilidade e desgaste, entre outras, quando elementos intersticiais como hidrogênio, carbono, nitrogênio ou oxigênio são introduzidos em sua rede cristalina [6,9,10]. Isto implica a importância da necessidade de controlar a composição e a estrutura durante o processamento superficial do titânio [7,8,11]. Devido a essas vantagens, o estudo das espécies do plasma tem recebido amplo investimento na intenção de aperfeiçoar processos utilizados nesses setores, utilizando técnicas capazes de analisar o plasma, como a espectroscopia de emissão óptica (OES), sonda de lagmuir, espectroscopia de massa, entre outras, e técnicas indiretas aplicadas em amostras expostas à ação do plasma, como por exemplo, ensaios de dureza, medidas de espessura da camada tratada, ensaios de ângulo de contato e tensão superficial, atrito [33,34,35,36].…”

RESUMOO presente estudo mostra uma relação entre o comportamento das espécies ativas do plasma com as propriedades superficiais do titânio. Para tanto, espécies ativas como N 2 + (391,4 nm) e O (844,6 nm) foram analisadas por espectroscopia de emissão óptica (OES) em plasma produzido por uma mistura de gases ABSTRACTThe present study correlates plasma active species with titanium surface properties. This was achieved by performing optical emission spectroscopy (OES) analysis of N 2 + (391.4 nm) and O (844.6 nm) within a N 2 -A r -O 2 plasma. The fluxes of gases were established to be 1 and 4 sccm (standard cubic centimeter) for nitrogen and argon, while that of oxygen was varied between 2 and 4 sccm. A non-linearity of the intensity of N 2 + (391.4 nm) species with the increase on O 2 flux was observed with an intensity peak at 3 sccm. It was also concluded that the active species influence the modification of properties after the plasma treatment. The N 2 + (391.4 nm) species were more effective to form nitrides and the surface roughness was bigger when those species presented higher intensity. Surface hardness and surface stress were also higher whenever using higher intensity fluxes of N 2 + (391.4 nm). Furthermore, while the N 2 + (391.4 nm) specie influenced the dispersive component, the O (844.6 nm) specie influenced the polar component.

“…These alloys have also been used in other application such as in orthopedics, for bone fixation devices, total hip and knee replacements in both the cast and wrought forms. However, despite these properties, the fabrication processes, such as casting, cutting and plastic works are usually difficult due to their high melting point (1623 -1723 K), hardness and limited ductility [14] [15]. Therefore, this contribution reports on the fabrication of FA/Co-Cr-Mo nanocomposite using Pulsed Laser Deposition method and a possible application in dentistry.…”

Aim: The study was to fabricate FA nanopowder/Co-Cr-Mo dental alloy nanocomposite using pulsed laser deposition (PLD), and to evaluate bioactivity properties on simulated body fluid. Methods: In this work, the FA nanopowder was prepared by mixing calcium hydroxide (Ca(OH) 2 ), phosphorouspent oxide (P 2 O 5 ) and calcium fluoride (CaF 2 ) in a planetary high energy ball mill using zirconium vial. Fluorapatite (FA) nanopowder was processed in the form of pellet for pulsed laser deposition process. The Co-Cr-Mo alloy was coated with FA nanopowder which was approximately 35 -65 nm at various laser energy, pressure and time. The X-ray diffraction (XRD) was used to analyze phase, crystallinity and size distribution of Co-Cr-Mo/FA nanocomposite. The surface analysis was by scanning electron microscopy (SEM), Atomic Force microscopy (AFM) and Energy dispersive spectroscopy (EDS). Results: From the results obtained, It was shown that FA nanopowder deposited on Co-CrMo alloy was stable during 14 days of incubation on simulated body fluid. It was also observed that the FA nanopowder coated on the surface of the alloy was still intact after the deposition process, which indicated the bioactivity and biocompatibility of the material. Conclusions: The fabrication of FA nanocomposite based dental alloys (Co-Cr-Mo) using PLD was done successfully. This was confirmed by various characterization techniques, which included XRD, AFM, SEM and EDS.
