Brun, Etienne. « Influence des paramètres d'élaboration sur les propriétés mécaniques et microstructurales de microballons métalliques obtenus par électrolyse ». Thesis, Dijon, 2012. http://www.theses.fr/2012DIJOS112.
Texte intégralThe aim of this PhD Thesis is to study the gold-copper cyanide electrochemicalsystem and finally to realize gold-copper microspheres with a diameter of 800 μm and athickness between 20 and 40 μm. The composition, the microstructure and the roughness ofthese shells must be perfectly controlled. To synthesise such a material, electrodepositionfrom a gold-copper alkaline cyanide bath has been chosen.Initially, the influence of the principal electrochemical parameters (temperature of theplating bath, stirring, etc.) was studied. This study showed that it is possible to realize5 μm thick gold-copper alloys with various compositions. Actually, it was shown that thecopper content of deposits varies with the applied potential. When increasing the coppercontent of coatings, the nucleation and growth mechanisms change. As a result, the grain sizeand the microhardness of the coatings are modified. An increase in the copper content reducesthe grain size witch increases the microhardness until a critical grain size of 6 nm. Thisincrease of copper content also affects the microstructure: columnar, nodular even dendriticalstructures were observed.Then, 20 μm thick gold-copper coatings were realized using the same electrochemicalparameters. As expected, these coatings were very difficult to plate because of the instabilityof the electrocrystallization process resulting in the development of columnar and nodularstructures. Moreover, for thicknesses above 10 μm, all deposits are free from copper. Themicrostructure change of deposits can be explained by inhibition phenomena generated byfree cyanide. Actually, the reduction of gold-copper generates free cyanide at the cathodesurface which inhibits the electrocrystallization and promotes instantaneous nucleation. Thisproduction of free cyanide also modifies the electrolyte chemistry promoting the formation ofCu(CN)43- instead of Cu(CN)32-. Cu(CN)43- complexes have lower diffusion coefficients andhigher activation energy witch explains why copper content reduces when increasing thethickness of deposits.Then a model was established which explains the influence of free cyanide on thegold-copper electrocrystallization. This model permitted to develop solutions in order to limitthe inhibition phenomena and to optimize the electrocrystallization of gold-copper.One of the solutions developed is the application of an ultrasonic field. The cavitationgenerated by the ultrasonic field eliminates the free cyanide from the cathode surface andoptimize the electrocrystallization process. Gold-copper deposits on shells were then platedunder sonication. SEM and EDS results show that it is possible to make 20 to 40 μm thickcoatings with a controlled composition. All the coatings plated under sonication were smooth(80 ≤ Ra ≤ 230 nm) and compact for various copper contents. The microhardness of thesecoatings varies with grain size (Hall-Petch relation) which depends of copper content

Texte intégralSince 1996, the CEA's Military Applications Division (DAM) guaranties the reliability and safety of Frenchnuclear warheads without conducting any further nuclear test. It relies particularly on major facilities forvalidating the equations used to model the functioning of nuclear weapons. Among them, the Megajoule Laser(LMJ) allows studying experimentally, as "laboratory" measurements, representative phenomena gatheringtime·scale and space distribution of extreme temperature and pressure conditions. These experiments are ledwith millimetric objects named microshells. Before experimenting them, these microshells are characterizedusing X·rays technics. On the radiographies, one can observe straight gray level variations which are generatedby the phase contrast phenomenon added to x·rays absorption contrast. Information included in this formercontrast is used to sharply determine microshell's edges. The delimiting points of these edges are thenintegrated as input data to compute microshell's surface form defects. A study is also led to determine theoptimized number of radiographies needed for estimating the search defect modes. Measurement uncertainty isfinally evaluated, thus giving a complete microshell's characterization

Texte intégralThe inertial confinement fusion experiments require cryogenics targets fabrication, which is mainly a smooth uniform solid hydrogen isotopes (DT) layer at 20K. This layer is modelled in a plastic microshell that is placed in a gold cavity. One of the challenges of this program is to guarantee roughness and uniformity of the layer. Similar objects does not exist at ambient temperature. This report presents three methods convenient to characterise this layer in cryogenic conditions, with only one observation direction. The first one, shadowgraphy consists of the observation of the microshell thank to an optical system. The analyse of shadowgraph allows the DT layer characterisation in an equatorial plan. The two others techniques are the optical coherent tomography and the wide band interferometry. These methods provide the measurement of the layer thickness at the poles of microshell. The interference patterns are formed by the interference on two waves. The first one is reflected on a reference mirror, the second one is reflected on the interfaces of the microshell. The performances and uncertainties of the methods are analysed
Lattaud, Cecile. « Synthesis of low density foam shells for inertial confinement fusion experiments ». Thesis, Dijon, 2011. http://www.theses.fr/2011DIJOS033/document.
Texte intégralThis work deals with the fabrication process of low density foam shells and the sharp control of their shape (diameter, thickness, density, sphericity, non-concentricity). During this PhD we focused on the non-concentricity criterion which has to be lower than 1%. The shells are synthesized using a microencapsulation process leading to a double emulsion and followed by a thermal polymerization at 60°C. According to the literature, three major parameters, the density of the three phases, the deformations of the shells along the process and the kinetics of the polymerization have a direct influence on the shells non-concentricity. The results obtained showed that when the density gap between the internal water phase and the organic phase increases, the TMPTMA shells non-concentricity improves. A density gap of 0.078 g.cm-3 at 60°C, leads to an average non-concentricity of 2.4% with a yield of shells of 58%. It was also shown that the synthesis process can be considered as reproducible. While using the same internal water phase, equivalent non-concentricity results are obtained using either a straight tube, a tube with areas of constriction or a short wound tube. The time required to fix the shell’s shape is at least 20 minutes with thermal polymerization. So, it seems that the time spent by the shells inside the rotating flask allows the centering of the internal water phase inside the organic phase, whatever the circulation process used. In order to get higher polymerization rates and to avoid destabilization phenomena, we then focused our study on photopolymerization. When the synthesis is performed using a UV lamp with an efficient light intensity, the shells have a slightly higher thickness than the shells synthesized by thermal polymerization. Moreover, a really higher yield, around 80%, is achieved with UV polymerization. However, the average non-concentricity of the shells synthesized lays around 20%, which is really high compared to the 2.4% average non-concentricity obtained with thermal polymerization. It would be interesting to expose the shells to UV light at different times after collection in order to study the influence of the agitation time on the shells non-concentricity
