“…Magnesium is an important engineering material with applications including aviation gearbox casings [22], orthopedic biomaterials [23] and various lightweight components in the automotive industry such as engine blocks, transmission cases and wheel rims [24]. The Magnesium Elektron WE43 alloy is well suited to be characterized by XCT and DVC due to the low X-ray attenuation of Mg and the heterogeneous microstructure of the alloy that contains precipitates with strong X-ray attenuation (approximately 4wt% Yt and 3wt% rare earths such as Nd [25]).…”

“…They are classed as electrochemically active corrosion inhibitors [7][8][9]. Examples of conductive polymers include polyacetylene, polypyrrole, polythiophene, polyaniline, polyphenylene and poly (p-phenylenvinylene), which are all systems containing conjugated double bonds with charge carriers providing charge transfer along the chain [10][11][12]. Polyaniline is probably the oldest synthetic conductive polymer [13].…”

The effect of pigment particle surface treatment with polyaniline and polypyrrole on the corrosion inhibiting properties of organic paints was investigated. Mixed oxides possessing the spinel and perovskite structures were synthesised for the study. Coatings based on an alkyde resin were prepared for the investigation of the corrosion protection properties of the pigments, the surfaces of which had been provided with a polyaniline and polypyrrole layers. Laboratory corrosion tests were applied to the paint films. Polyaniline phosphate was found preferable to polypyrrole as the modifying agent of the pigment surface regarding the pigment's corrosion inhibiting efficiency.

“…Therefore, much research has tried to increase corrosion films on magnesium by thermal sprays [6,7]. Truong et al and Kannan et al reported corrosion resistant polymer films on magnesium [8,9]. The corrosion problem of magnesium 4 still remains however, and an effective coating for corrosion protection is still needed.…”

Liquid phase deposition treatment (LPD) was applied to form a corrosion protective titanium dioxide (TiO 2 ) film on commercially available pure magnesium. Changing the solution pH, from acidic to highly alkaline, and with the addition of sucrose, it becomes possible to form a highly adhesive and thin TiO 2 film on commercially available pure magnesium without any heat treatment. The role of the sucrose may be attributed to the formation of tetrafluoroboric acid (BF 4 ) -in the solution reducing the homogeneous nucleation of TiO 2 in the LPD solution. The film formed in the weak alkaline environment shows better corrosion resistance than at other LPD conditions, while the average rest potential is the same as that of as-polished specimens. This low rest potential may be due to micro-cracks in the formed film and high activity of the magnesium substrate.
