Friction Surfacing Cladding (FSC) is a relatively new solid state process to deposit thin metallic clad layers on substrates. It employs a hollow rotating tool that supplies the clad material. Frictional and viscous heating take place that soften the clad material and enhance the bonding of the clad material to the substrate. Thin layers of commercially pure aluminium can be deposited well on a...

The present study aims at assessing the mechanical behavior of aluminum alloy (AA2024) subjected to exfoliation corrosion. material was exposed high temperature and subsequent low (HLA) treatment further heat-treated samples were corrosion for duration 48 96 h room temperature. HLA increases retention property in corrosive environment. Further, hardness impact strength also increased under envi...

Friction Stir Welding (FSW) is an innovative solid-state joining process, which is gaining a great deal of attention in several applicative sectors. The opportune definition of process parameters, i.e. minimizing residual stresses, is crucial to improve joint reliability in terms of static and dynamic performance. Longitudinal residual stresses, induced by FSW in AA2024-T3 butt joints, have bee...

This research aims to investigate the material flow behaviour and microstructure evolution in friction stir welded joints of dissimilar aluminium alloys AA2024/AA5086. AA2024 plate was placed on re- treating side; using threaded conical flat shoulder tool rotating at 635 rpm moving along joint line with a speed 75mm/min. Mixing both clearly visible zone resulted features typical welding solid s...

The effects of surface pretreatment on the rate of scribe-creep caused by underpaint corrosion on coated AA2024-T3 (UNS A92024) were investigated. Scribe-creep experiments were conducted on epoxy polyamide-coated (average coating thickness: ~10 μm) AA2024-T3 in 80% relative humidity at 25°C, 40°C, and 50°C. Scribe-creep was observed to be enhanced by exposure test temperature regardless of surf...

In this study, we explored the effects of a laser cleaning process on surface properties an aerospace aluminum alloy. We performed AA2024 Through SEM and EDS analyses alloy samples after cleaning, effect under different energy densities was studied. After residual stress, hardness, friction, wear tests were samples. The experimental results demonstrated that oxides could be effectively removed ...

Cerium-based compounds have been studied for decades as non-toxic candidates the protection of aerospace aluminium alloys (AAs) like AA2024-T3. However, complex heterogeneous microstructure these has hindered a thorough understanding subsequent stages corrosion provided by this class inhibitors. Thus, work is devoted to unravelling interaction mechanisms different intermetallic particles (IMPs)...

Aluminium alloy (AA2024-T4) is a material commonly used in the aerospace industry, where it forms part of fuselage aircraft and spacecraft thanks to its good machinability strength/weight ratio. These characteristics allowed be applied construction structure pilot plant produce biological extracts nano-encapsulated bioproducts for phytosanitary control diseases associated with microorganisms cr...
