Testo completoA surface treatment process, developed for C40E steel substrates before alumina plasma spraying, has been extended to nickel substrates. As an alternative to sand blasting, nickel substrates were pre-oxidized under CO2, to create a protoxide nickel layer of controlled thickness. This oxide layer significantly increases the alumina coating adherence on nickel substrates. A kinetic study of nickel oxidation under CO2has been realized, in order to better control the nickel preoxidation. TEM investigations of alumina/nickel interfaces showed a heteroepitaxial growth of alumina on nickel monoxide, which justify the strong alumina coatings adhesion. This high adherence (around 105 MPa) has been measured using a modified tensile test (ASTM C633-13), specifically set up for pre-oxidized steel C40E substrates

Testo completoThe resistance to isothermal and cyclic oxidation of alloy 718 produced by laser beam melting (LBM) and electron beam melting (EBM) was compared to that of wrought alloy 718 (AMS5662). Isothermal oxidation tests at 850 °C in air showed similar oxidation behaviour in terms of weight gain and intergranular oxidation for all three alloys. The effect of roughness on oxidation kinetics was quantified and it was shown that the intergranular oxidation kinetics follow Wagner's model of internal oxidation partially controlled by the volume diffusion of Al. Cyclic oxidation tests at 900 °C showed a much more adherent oxide layer for the wrought sample than for the LBM and EBM samples. This could be due to a higher amount of sulphur in solution in the AM samples. The resistance to cyclic hot corrosion and cyclic oxidation at 900 °C and 1100 °C of superalloys from AM (Alloy A, IN738, C1023 and Hastelloy X) were compared. The tests carried out on CIRIMAT’s cyclic oxidation rig and on Safran Helicopter Engine’s burner rig showed similar mass variation kinetics on the two rigs despite the very different atmospheres, except for alloys strongly affected by hot corrosion at 900 °C on the burner rig. The alloys most susceptible to cyclic hot corrosion have a lower Cr content (Alloy A) and/or a high Mo content (C1023), and exhibit intergranular oxidation (Alloy A, C1023 and 738). Overall, for the densest materials, the results do not show significant differences between the samples made by AM and the cast samples. These results validate the use of these AM Ni-based superalloys, as far as high temperature oxidation-corrosion is concerned

Testo completoManganese oxide-based catalysts have been synthesized through different routes and evaluated in the Catalytic Wet Air Oxidation of ammonia. Such catalysts are active, selective towards molecular nitrogen and stable under the applied reaction conditions. Molecular nitrogen and nitrite are primary products. A detailed study of the impact of the operating conditions (manganese content, oxygen partial pressure, ammonia concentration, initial pH, and charge at the catalyst surface) on the catalytic performances was carried out. The selectivity in molecular nitrogen is optimum when i) the amount of catalyst is low, ii) the ratio nO2:nNH4+ is close to stoichiometry (˜ 0.75) and ii) the pH at the point of zero charge of the catalyst is neutral. Although strongly basic conditions (pH 13) improve the catalytic activity, the conversion nitrite to nitrate is inhibited and the selectivity in molecular nitrogen is degraded. From a kinetic point of view, the reaction order with respect to oxygen and ammonia are 0 and 1, respectively. The influence of the oxidation state of manganese (+II, +III and +IV) in the presence of bulk manganese oxides or ceria-supported manganese oxides indicated that the active site would consist of a pair of Mn(+III) and Mn(+IV). The reaction makes the active site and the oxides where manganese is initially present at a low oxidation state are markedly modified upon reaction. A synergy between manganese and cerium is also confirmed, involving the two Mn(+III)/Mn(+IV) and Ce(+III)/Ce(+IV) redox couples in a concerted way

Testo completoIn the present study bond formation reactions between soot precursors and their role in the soot inception process is investigated. The soot precursors were generated in macroscopic detailed gas-phase kinetic calculations and according to certain criteria introduced in simulation boxes to model bond formation between soot precursor molecules with reactive force field molecular dynam-ics modeling. The impacts of temperature, fuel mixture and equivalence ratio have been investigated on the rate and structure of the newly formed molecules. The resulting structures compare well to previously reported experimental results. Furthermore, the bond formation rate between PAH is found to be linearly correlated with the temperature at which the PAH precursors are generated, while fuel and equivalence ratio do not have a direct impact on the reaction rate. The generated growth structures are lumped in: 1) directly linked, 2) aliphatically linked and 3) pericondensed polycyclic hydrocarbons. It is found that the amount of aliphatically linked PAH increases with the amount of aliphatic content of fuel mixture. Finally, a reaction scheme is presented displaying the most representative reaction pathways to form growth structures in each lumping class and their eventual intercon-version. The present work – that applies a combined approach of macroscopic gas-phase kinetic calculations and atomistic reactive force field simulations – offers a good alternative to obtain structural differences of nascent soot for a broad range of thermodynamic conditions and detailed reaction mechanisms for soot inception process

Testo completoWith the depletion of fossil fuel resources, the search for new alternatives such as biofuels produced from biomass has intensified. A wide variety of compounds can be produced by treating this biomass. Ethers are one of them and can be used as additives to conventional fuels or as fuel. To this end, it is necessary to have a better knowledge of the kinetics of the oxidation of these compounds which differ from conventional fuels by the presence of oxygen atoms in their structure, making the chemistry more complex. This thesis aims to develop kinetic mechanisms of the oxidation of simple ethers based on experimental data obtained in jet stirred reactor. The oxidation of four ethers at atmospheric pressure and high pressure (10 atm) was studied over a wide range of temperatures (450 - 1250 K) under different equivalence ratios (0.5 to 4). The mole fraction profiles of the reactants, products of combustion and main stable intermediates were measured by gas chromatography, infra-red spectrometry or photoionization mass spectrometry using synchrotron radiation. The results thus obtained then served as a basis for validating kinetic mechanisms modeling the oxidation of these species whose agreement with the measurements is globally satisfactory for compounds for which few studies are available

Testo completoGas Fast Reactor (GFR) is one of the different Generation IV concepts under investigation for energy production. SiC/SiC composites are candidates of primary interest for a GFR fuel cladding use, thanks to good corrosion resistance among other properties. The mechanisms and kinetics of SiC oxidation under operating conditions have to be identified and quantified as the corrosion can decrease the mechanical properties of the composite. An experimental device has been developed to study the oxidation of silicon carbide under high temperature and low oxygen partial pressure. The results pointed out that not only parabolic oxidation, but also interfacial reactions and volatilization occur under such conditions. After determining the kinetics of each mechanism, as functions of oxygen partial pressure and temperature, the data are used for the modeling of the composites oxidation. The model will be used to predict the lifetime of the composite in operating conditions
