Technological Forms Develope in Different Morphological Fields

The present work is takes in consideration the experimental study of the influence of some morphological fields regarding the development of the complex technological forms. The goal that we have set in this paper was to bring in new points of view on technology morphologies arising in technological processes, whose goal is to generate surfaces.The development of the technological shapes could be controlled and oriented from the quality and quantity point of view, by using the morphological fields.. We refer here in particular to complex forms, not the Euclidean upon which adequate studies have been done already. Among the illustrations of the experimental parameters of forming events, electrochemical deposit is regarded as a paradigm for theoretical studies of diffusion limited aggregation. In fact, by changing the concentration of metal ions, the cathodic potential and the morphological field you can explore different morphologies, such as: dense radial aggregates, dendridic patterns and fractal aggregates. This topic has been treated and shown in the paper. The box-counting algorithm was used in calculating the fractal dimension of the deposited agregates.

Fabrication and Magnetic Properties of Fe, Co and Ni Nanotube Arrays

One-dimensional Fe, Co, Ni nanotube arrays ware fabricated successfully by the electrochemical deposit in porous anodic alumina oxide (AAO) templates. The microstructure of nanotubes were observed by scanning (SEM) and transmission electron microscopes (TEM) respectively. The obtained Fe, Co, Ni nanotubes are arranged orderly. The magnetic property of nanotubes was measured and analyzed. The results show that the residual magnetization of Ni nanotubes is the biggest, and that of Fe nanotubes is the smallest. It is easy to be magnetized along the axial direction.

Applied Conditions for a Diffusion Electrochemical Method for Surface Streamlines Visualisation

The setup of the surface flow visualisation by electrochemical deposit has given good results in the case of different flow types and in particular in the case of solids in rotation [1- 4]. This technique is based on the mass transfer principle towards a reactive surface electrode on which the studied flow will be visualised. This visualisation method of the surface streamlines by electrochemical deposit has allowed to understand the flow between a rotating and fixed discs. The inlet phenomenal named edge effects have been clearly seen during the visualization and the theoretical study. The purpose of this study is to precise the wide range from the surface streamlines configurations.
