Der volle Inhalt der QuelleThe structuring at sub-micronic scale of the surface of stainless steels allows to provide them with new functionalities, for example for tribological and optical applications. This thesis is part of the ANR SPOT project which aims to structure the surface of austenitic and martensitic steels on a submicronic scale by dry etching. In this work, we have developed a plasma process with a mixture of chlorine and argon for the etching of stainless steels. The development of this process was carried out based on the study of the etching of the main metals that make up these steels, namely, iron, chromium and nickel. Based on measurements of etching speeds, as well as on plasma diagnostic techniques, we have shown that, in a chlorine and argon plasma, iron is the most etched element, followed by chromium, then nickel. The metallic and the stainless steels etched samples were analyzed by surface characterization techniques, in particular X photoelectron spectrometry (XPS) analyzes. We have also studied the variation of the etching speeds of these metals and steels as a function of the temperature of the substrates. These studies have enabled us to establish the mechanisms involved in the etching of metallic elements. We have shown that in a plasma of chlorine and argon, iron is mainly etched by a chemical mechanism which follows an Arrhenius law. This mechanism would be based on the formation of volatile iron chlorides. In the case of chromium, the etching requires ionic assistance in order to desorb the non-volatile chromium chlorides formed on the surface of the material. Finally, for nickel, we observed that the etching speed decreases when the temperature increases. In this case, observations with a scanning electron microscope made it possible to highlight the formation of swellings rich in chlorine. XPS analyzes of the etched surface of nickel suggest that these swellings are due to the formation of non-volatile nickel chlorides. These chlorides would be at the origin of the decrease in the rate of etching of nickel, the sputtering of which would be blocked by the presence of these chlorides. Understanding these mechanisms led to conclude that, in a chlorinated plasma, the blocking element in the etching of stainless steels is nickel

Der volle Inhalt der QuelleThe New Caledonia nickel laterite ore deposit, developed at the top of the Peridotite Nappe, hosts about 20% of the nickel resources worldwide. In order to better understand the formation of this eposit, our study, focusing on the Koniambo Massif, is not restricted to the ore zone but concerned with the whole peridotite pile. Our approach combined: i) the analysis of the internal deformation of the massif, ii) the isotopic characterization of quartz and magnesite veins which are suspected to represent by-products of the laterization process, iii) the 3D modelling of the lateritenickel ore deposit, based on a dataset of ~6000 subsurface boreholes and the study of some outcrops located into the mineralized area. The spatial and temporal evolution of the deformation associated with serpentinization is described across the ~800 m-thick rock pile of the Koniambo Massif. The upper part of the massif is densely faulted and preserves the record of two early deformation events. The first one is associated with synantigorite faults and the second one with syn-polygonal serpentine faults. The ~200m-thick serpentine sole is composed of breccias and mylonites and records pervasive tangential shearing associated with polygonal serpentine and magnesite. Thus, the serpentine sole represents a major décollement at the base of the nappe. Between the sole and the upper part of the massif, anintermediate structural level is identified, characterized by the presence of plurimetric shear zones that probably merge with the sole.The 3D characterization of the nickel distribution in the saprolite level, at both deposit and outcrop scales, gives evidence for processes implying not only vertical (as commonly assumed) but also lateral nickel redistribution. This lateral transport ismechanical or associated with fluids and leads to significant local enrichments. The isotopic characterization of the quartz veins associated with garnieritic ore shows that they formed under low temperature hydrothermal conditions. The structural and isotopic (coupling “stable isotope” and “clumped isotope thermometry”) characterization of the magnesite veins located at the serpentine sole shows that they are syn-tectonic and derived from low temperature meteoric water. As a result, we propose that active tectonics has enhanced the infiltration of the meteoric waters involved in the laterization process down to the base of the nappe

Der volle Inhalt der QuelleThe geological unit called Szklary Massif comprises two environments containing Ni and Cr from diverse origins: lithogenic (serpentine soils) and anthropogenic (pyrometallurgical waste) origins. The study was dedicated to investigate the distribution and mobility of Ni and Cr occurring within this small area. The approach is first based on mineralogical characterization of the Ni and Cr bearing minerals using analytical instrumental methods (XRD, SEM-EDS, EPMA, micro Raman, TEM, ICP-MS). Later complementary chemical extractions not only provide information about the actual solid speciation of Cr, Ni. They also allow discussing about potential mobility and forthcoming environmental impact induced by the abundance of Ni and Cr and by the presence of other elements (Co, Cu, Pb and Zn), especially in soils cultivated in the dump vicinity. The multidisciplinary approach gives concordant and complementary results. The direct mineralogical approach, consisting in characterization of primary and secondary mineral phases, provides qualitative information about the stability of potentially toxic elements (PTE) in minerals in the present weathering conditions (well drained soils, enriched in organic matter, within neutral to basic pH, submitted to transitional temperate climatic conditions). The chemical extractions specify the solid speciation of PTE in a quantitative way and evidence implication of organic and amorphous phases in the PTE immobilization. In addition, mineralogical investigations of the solid residues after sequential extractions allow assessment of the real effect of the chemical extractants used on the studied materials. The use of combined approach evidenced relative stability of Cr compared to Ni. Moreover, the study confirms contamination of the cultivated soils located next to the waste dump. The environmental risk is related not only with Ni and Cr but also with other PTE such as Zn and Cu, which are present in significant proportions within biodisponible fractions

Der volle Inhalt der QuelleNew Caledonian ferritic soils (more than 50 % of iron) are naturally rich in metals (chromium, nickel, cobalt, manganese) and deficient in nutrients (nitrogen, phosphorous, potassium). Nevertheless, New Caledonia is recognized as a hot spot of vegetal biodiversity, and is a natural laboratory for studying adaptation strategies of plants to metalliferous soils, and more particularly the (hyper)accumulation phenomenon of metals by plants. Understanding those mechanisms is notably needed to develop revegetalization techniques of ecosystems after mining exploration or phytoremediation of polluted sites for instance. Thus, to better understand soil-plant relationships, speciation and localization of manganese and nickel in all vegetal organs of different species and in soils were studied. In spite of a different speciation in soil, both nickel and manganese are under similar divalent organometallic complexes in plants, from roots to leaves, mainly in tissues with less active metabolism
