Повний текст джерелаThe fiberizing spinners used to produce the glass fibers undergo sizable mechanical, chemical and thermal solicitations. Therefore, this piece is degraded and must be periodically replaced. The purpose of these works is to increase the lifetime of the fiberizing spinners by improving the mechanical and chemical properties of the superalloys that constitute them. More precisely, the objective of this thesis is, in the first time, to improve the alloys used to fiberize at 1000°C, and in a second time, to find a superalloy that can fiberize at 1125°C. These works are focused on two families of superalloys: nickel-based and cobalt-based. The chemical properties are characterized by the thermogravimetry tests and the mechanical properties by 3 points flexural creep tests. For the Ni-based alloy, the influences of unwanted minority elements, Mn and Si, were studied. The mechanical properties of this alloy are subject to improvement tests by the addition titanium, zirconium, tantalum, hafnium and niobium. The aluminium addition was also experimented but with the aim of improving the chemical properties of the alloy. Finally, the studies were also driven on the addition of noble metals (Pd and Ru) and of rare earths (Y, La and Ce). Concerning the cobalt-based superalloys, the study focused on an alloy which has previously shown good general properties to be used at 1125°C and no at 1000°C. The versius with a lowered content in tantalum, without tungsten and without hafnium were studied. To close this work, the increase of nickel and a heat treatment were studied in order to improve the oxidation resistance of this second alloy

The microstructural characterization was made by Scanning Electron Microscopy (SEM), Scanning Electron Microscopy with Field Emission Gun (SEM-FEG), semi-quantitative microanalysis measures and chemical mapping by EDS, characterization by X - ray diffraction and mechanical test of hardness Vickers in all the samples. The results of the microstructural and mechanical characterization for 40Ni-3Ta alloy were similar to those found in the literature. The 40Ni-3Nb alloy showed the closest results, among the other alloys studied in comparison with the standard alloy.

This research made use of different chlorine concentrations and temperatures to explain the commercial cobalt-based super-alloys electrochemical properties and corrosion behavior of the commercial cobalt-based super-alloys in terms of the electrochemical polarization curves. Both SEM and the immersion experiments were used to explain the micro-structure and to understand the effect of temperature and concentration on the pit size. Several different solutions and concentrations were also applied to confer the critical pitting temperature (CPT) of the cobalt-based super-alloys. In three different chloride salts, the corrosion potential (Ecorr) are of little change of temperature and concentration, and the pitting potential (Eb) gradually decreased as temperature increases. Among them, Fecl3 is a rather special case in which the difference between Ecorr and Eb in potential are relatively small which implies the alloy immediately pitted right after the specimen being scanned beyond the Ecorr. The corrosion morphology of the alloy tested in three kinds of chloride solutions at 80oC observed by SEM shows that the corrosion all initiated preferentially at the interdendritic regions which were eventually merged into larger area as time goes on; the damage were particularly pronounced for Fecl3 than the other two.

Cobalt-based superalloys are used extensively in applications requiring good wear resistance, corrosion resistance and heat resistance. Many of the properties of these alloys arise from the crystallographic nature of cobalt, the solid solution strengthening and carbide precipitation effects of chromium, tungsten and molybdenum. Metal matrix composites are known to exhibit exceptional wear resistance; therefore, several investigators have used titanium carbide (TiC) as a reinforcing medium in a ferrous metal matrix in order to enhance this property. TiC has proved its suitability in Fe or Fe-based alloys due its high hardness, low density and chemical stability with Fe-based alloys. In this study, we have mixed and added different amounts of TiC powders (10, 15 and 20 wt %) to the Cobalt-based superalloy powders. The mixing processed was finished by ball milling and granulation in a laboratory. In addition, the mixing powders (Cobalt-based superalloy and TiC) were sintered at 1260, 1270, 1280 and 1290°C, and then a series of HIP processes and heat treatments were performed. Meanwhile, the parameter of HIP treatment was 1250°C, 125 MPa and 100 min. The heat treatment processes were heating to 1100°C and maintaining for 40 min for quenching; aging at 760°C and soaking time was 6, 9, 12 h, respectively. Various materials characterization techniques were used to evaluate the materials’ properties and microstructures, including: apparent porosity, hardness test, transverse rupture strength (TRS) test, OM, and SEM microstructral examinations. The experimental results show that the highest TRS value of 1566.7 MPa was obtained by the 15 wt% TiC additive powder, which was sintered at 1280°C and then followed by HIP process and solid solution heat treatment. It also has been proved that the closed pores can be effectively eliminated (1.2% → 0.86%) by HIP treatment; in addition, the M6C carbides can produce more uniform precipitation on the grain-boundary and matrix after heat treatment. Furthermore, the highest hardness value of HRA 80.4 was obtained by the 20 wt% TiC additive powder, which was only sintered at 1290°C.
