Airlife - Towards a Fleet Management Tool for Corrosion Damage

Sheet AA2024‐T3: a new investigation of microstructure and composition

“…[3] Consequently, corrosion of these alloys is still of relevance, particularly for structural health management systems. [4] In recent years, there has been significant development in characterisation techniques, both in detection systems as well as with computer power to analyse data. [5 -7] This paper describes a new characterisation study of AA2024-T3 which complements previous studies [8 -14] and elaborates the methodology for a report on the spatial relationships of the IM particles in AA2024-T3.…”

Optical Sensors for Corrosion Monitoring

“…7 For example, in Ref. Here, corrosion is also an important factor that can lead to material loss and cracks, which can be costly to support in terms of reparations and human lives.…”

“…Therefore, SHM systems can consist of a wide number of sensors and transmission systems for an adequate data management and health diagnosis. 7 Optical fiber sensors (OFSs) are emerging as a superior technology capable of carrying out this purpose as well as offering other attractive performances derived from the particular characteristics of the silica, such as small size, light weight, large durability, immunity to electromagnetic fields, low losses at optical frequencies, large bandwidth, easy integration in existing and new structures, and resistance to high temperature and corrosive and hazardous environments. [1][2][3][4] Some of the key parameters to be monitored for SHM are temperature, humidity, acidity, salinity, UV radiation, carbonization, deformation, strain, fatigue damage, and corrosion.…”

High Strength Al-Alloys: Microstructure, Corrosion and Principles of Protection

“…The objective is to move from a purely phenomenological description of corrosion to a level of understanding where the corrosion process can be predicatively modelled. This level of understanding is primarily aimed at developing structural health management algorithms for maintenance management and several approaches to this are already outlined in the literature (Hughes, Hinton et al 2007;Cavanaugh, Buchheit et al 2010;Ralston, Birbilis et al 2010), (Trueman 2005). The determination of appropriate metrics for the compositional and electrochemical characteristics for IM particles is not so straight forward and is addressed below.…”
