Initial characterisation of mechanical and corrosion properties of stationary shoulder friction stir welded bare and Alclad AA2024-T3 butt joints

Aluminium alloy AA2024-T3 is a lightweight and damage tolerant material, and is therefore often used in aerospace applications. However, this alloy is difficult to weld using conventional fusion welding techniques due to defects caused by the meld pool.<br/> <br/>Friction stir welding (FSW) was developed by The Welding Institute (TWI) in 1991 in...

Correlating laboratory tests with service life performance of marine coating systems

Accelerated tests have been commonly used by the marine coating industry to evaluate the performance of a coating in a short duration of time. Replicating natural exposure in an artifi- cially simulated manner is a challenging task due to the various factors that induce corrosion in the natural environment. Continuous salt spray testing is a...

Accelerated corrosion test simulation: Lattice model vs. continuum model

A series of accelerated corrosion tests were done by SGS INTRON (commenced by Combinatie Aanpak Maastunnel, constructor of the Maastunnel project) to investigate for a proper repair material for the deteriorated concrete floor in the Maastunnel at Rotterdam. Five types of fiber reinforced mixtures with different tensile behavior ranging from...
