1. ToF-SIMS Characterization of Nanostructured ZrO2 Coatings Applied to Near Equiatomic Ni-Ti Alloy
The ToF-SIMS technique was applied to analyze thin ZrO2 coatings deposited on the surface of a Ni-Ti alloy. Due to its nanostructured nature, these films are difficult to characterize by conventional techniques. ZrO2 coatings were deposited on near equiatomic Ni-Ti wires by pulse electrodeposition. Part of the samples was electrolytically polished before the

2. Efeitos da Espessura da Fita Metálica no Metal de Solda Utilizando Cavacos de Titânio Como Componentes do Fluxo em Arames Tubulares para a Formação de TiC
Resumo Cavacos de titânio foram utilizados como componentes do fluxo em arames tubulares fabricados a partir da conformação e trefilação de fitas metálicas com espessuras diferentes. Os arames apresentaram diâmetros internos com dimensões diferentes afetando as taxas de preenchimento do fluxo. Para as mesmas condições de soldagem, os arames fabric

3. Performance and Surface Integrity of Wire Electrical Discharge Machining of Thin Ti6al4v Plate Using Coated and Uncoated Wires
Wire Electrical Discharge Machining (WEDM) is one of the most important production technologies to manufacture very accurate small components and tools on any electrical conductive material. Titanium and its alloys have been widely used in automobile and aerospace industry as well as in medical engineering field. Small components and tools with complex geome

4. Surface Characterization of NiTi Superelastic and Shape Memory Alloys After Electrolytic Polishing
For the biomedical application of NiTi alloys, an excellent surface finishing process is required to guarantee high corrosion resistance and biocompatibility, eliminating the allergenic and toxic effects associated with the release of nickel ions in the body. Electropolishing is a process that can reduce surface imperfections and form a thin protective layer

5. Crystallization of II-VI semiconductor compounds forming long microcrystalline linear assemblies
In this work we report the formation of long microcrystalline linear self-assemblies observed during the thin film growth of several II-VI compounds. Polycrystalline CdTe, CdS, CdCO3, and nanocrystalline CdTe:Al thin films were prepared on glass substrates by different deposition techniques. In order to observe these crystalline formations in the polycrystal

6. Electro-thermomechanical characterization of Ti-Ni shape memory alloy thin wires
The use of shape memory alloys (SMA) as smart structures and other modern applications require a previous evaluation of its performance under load as well as a training procedure. In general, these requirements lead to the design and assembly of a specific test bench. In this work, an experimental set-up was specially designed to perform the electro-thermome

7. The thin wires modeling using the transmission line modeling method (TLM) / Modelagem de condutores finos utilizando o mÃtodo de modelagem por linhas de transmissÃo (TLM)
Numeric methods have been a very attractive alternative in the analysis and solution of problems in electromagnetic fields. Those are applicable to a high variety of problems involving complex geometry, heterogenic material composition and boundary condition diversities. This research has the objective of studying the modeling of thin wires using the numeric

8. Constitutive laws for strong geometric non-linearity
This paper is divided into two different parts. The first one provides a brief introduction to the fractal geometry with some simple illustrations in fluid mechanics. We thought it would be helpful to introduce the reader into this relatively new approach to mechanics that has not been sufficiently explored by engineers yet. Although in fluid mechanics, main

9. In vitro colonization of Streptococcus mutans on enamel.
An in vitro model consisting of enamel from extracted human molars, suspended from wires in inoculated culture tubes, was used to study the adhesion of bacteria to enamel. Under conditions in which there was no macroscopically visible plaque formation, electron micrographs showed no bacterial deposits on the enamel surface. In samples where Streptococcus mut
