Full textThis work is devoted to a study of the electrochemical behaviour of binary aluminiumcopper model alloys. Binary aluminium-copper alloys were deposited using physical vapour deposition PVD. Like that, the model alloy layers containing 0. 1 to 100 at % Cu were prepared to a thickness about 450 nm. A good correlation has been established between the metallurgical phases into these alloys and the equilibrium phase diagram. The microstructure evolution with chemical composition has then revealed a strongly influence of the θ-Al2Cu phase (33 at % Cu). In the same way, the electrochemical behaviour of these alloys in a sulphate media was correlated to the evolution of their microstructure. For a composition close to that of θ-Al2Cu phase (33 at % Cu), a transition of the electrochemical behaviour was again observed. Galvanic coupling between model alloys containing both α-Al and θ-Al2Cu phases shows that the anodic α phase remained in the passive state whereas pits were observed on cathodic θ-Al2Cu phase. The second part of this work concerns the chemical and structural studies of the anodic films grown on these alloys. From 0. 2 at % Cu in alloy, anodizing led to a copper enrichment just beneath the film in a 2 nm thin thick layer. For a sufficient copper content in the alloy, oxidation of copper was observed. From 2 at % copper content, the voltage-time response during anodizing wasn't linear and the RBS analysis revealed a difference between the calculated and measured values of the enrichment copper content. Then, from this composition copper is oxidised and incorporated into the film and oxygen bubbles are formed leading to a defective structure of anodic films, which has a strong influence on the electrochemical behaviour of these anodized alloys.

Full textIn the current work, we investigate the nondestructive evaluation of a thermal sprayed coating (Hastelloy C22 Ni-based alloy) on substrate (type 304 austenitic stainless steel) using acoustic microscopy and ECT method. Two models were built for the evaluation of this kind of material: one is for acoustic V(z) measurement and the other is for swept eddy current measurement. The implementation of these two models is used for the evaluation and properties measurement of the thermal sprayed coatings, such as elastic properties, electromagnetic properties. In particular, the main achievements and results are as follows: 1. Acoustic wave propagation in an anisotropic multilayered medium was investigated. The formula for calculating the reflection and transmission coefficients of the multilayered medium on or without a substrate were derived, which is necessary for the modeling of acoustic V(z) measurement of the thermal sprayed coating on substrate. 2. A model was built for the acoustic V(z) measurement of the thermal sprayed coatings on substrate, which can deal with anisotropic multilayered media. Specifically, we used a model of multilayered coatings with graded properties on substrate to calculate the acoustic reflection coefficient of our sample. Treating the thermal sprayed coating, deposited on a 304 steel substrate, as FGMs, we evaluated the coating thickness and the Young’s modulus evolution along the depth of the coating. 3. A model was built for the swept eddy current measurement of the thermal sprayed coatings. Since before the spraying process, the surface of the substrate is usually shot-peened (SP), the coated material is considered as a three-layer medium. The coating thickness and electromagnetic properties of each of the 3 layers were determined by an effective reverse process. 4. The thermal sprayed coated material after exposure in different conditions, i.e., as-received, heat-treated in air and heat-treated in SO2 environment, and after different exposure time was evaluated by the integrity of acoustic microscopy and ECT method. The coating thickness and the electromagnetic properties of the coated material under different conditions were measured
