thesis
In-situ investigation of elemental corrosion reactions during the surface treatment of Al-Cu and Al-Cu-Li alloys.
Abstract
This PhD thesis focused on the study of aluminum alloys, particularly the AA2024-T3 and AA2050-T3. The Al-Cu-Mg based alloy (AA2024-T3) are used for decades in the field of aerospace for its lightness and excellent mechanical properties are progressively replaced by and Al-Cu-Li (AA2050-T3) alloys. Nevertheless, they exhibit a highly heterogeneous microstructure, making them sensitive to corrosion. Several surface treatments formulations, such as coatings, have been developed, with the aim of slowing as much as possible the degradation of these alloys. The pretreatment, a preliminary step to surface treatment, is intended to prepare the surface of the alloy prior coating application. Several studies have shown that this step is essential and ensures the effectiveness of the surface treatment. In order to observe the effect of the pretreatment, several surface characterization techniques were used. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) are among the most cited. All these methods are intended to quantify the dissolution of the alloying elements. To date, none has been able to obtain a complete and in situ analysis of the elemental reactivity of a complex alloy during the pretreatment. The main objective of this thesis was to develop a new methodology capable of providing a precise measurement of the reactivity of complex alloys such as aluminum alloys during a pretreatment sequence and to provide information on AA2050 -T3, as very little is reported about the reactivity of Li during the surface treatment.
