1. Corrosion of galvanic pairs of dental alloys copper base with silver amalgams in artificial saliva
ABSTRACT Galvanic corrosion is a metal dissolution process that occurs when two metals of different electrochemical potential are immersed in an electrolyte causing electrical currents between the metals through the conducting medium. To restore lost or damaged teeth, different alloys are used, leaving the mouth exposed to electrical currents that circulate

2. Influência do eletrólito na eletrodeposição de nanopartículas de Cu sobre eletrodo de diamante dopado com boro
This paper presents the electrolyte influence on deposition and dissolution processes of Cu nanoparticles on boron doped diamond electrodes (BDD). Morphological, structural and electrochemical analysis showed BDD films with good reproducibility, quality and reversible in a specific redox system. Electrodeposition of Cu nanoparticles on DDB electrodes in thre

3. Evolução da microestrutura e da textura durante o processamento de chapas da liga Al-Mn-Fe-Si (3003) produzidas por lingotamento contínuo: um estudo comparativo com o processo semi-contínuo. / Microstructure and texture evolution of the Al-Mn-Fe-Si (3003) aluminum alloy produced from continuous casting process: comparative analysis with semi-continuous casting process.
The main reason for the development of this PhD Thesis was to compare the microstructures and textures of the 3003 aluminum alloy produced from continuous and semi-continuous casting processes. The roll caster process (continuous casting) has been increasingly used in the aluminum industry. Products usually obtained by means of heavy rolling operations in th

4. Dissolução eletrolítica de ligas de alumínio em cavacos e determinação dos elementos constituintes por espectrometria de emissão atômica com fonte de pasma (ICP-OES) / Electrolytic dissolution of aluminum alloys (Chip form) and multi-element determination by inductively coupled plasma optical emission spectrometry (ICP-OES)
Several aluminum alloys with different chips size were dissolved using aqua regia (HCl:HNO3,3:1). The residues of the dissolution procedure were either rejected or used in silicon volatilization with hydrofluoric acid before determination of Fe, Cu, Mn, Mg, Cr, Ni, Zn, Pb, Sn, Ti and Zr by ICP-OES. The influence caused by crescent amounts of aluminum in the

5. Dissolução eletrolítica para a determinação de elementos de liga em aço ferramenta por ICP-AES
Different methods have been applied to solve special problems of metal analysis. First, the solid samples of tool steels were analyzed by X-ray fluorescence. Alternatively, an on-line electrodissolution implemented in a flow injection system and conventional dissolution procedure for determination of W, Mo, V and Cr in tool steels by ICP-AES is described.
