Scalable corrosion resistant coatings for thermal applications
Corrosion of metallic substrates is a problem for a variety of applications. Corrosion can be mitigated with the use of an electrically insulating coating protecting the substrate. Thick millimetric coatings, such as paints, are generally more corrosion resistant when compared to nanoscale …

Aqueous hydrogen sulphide corrosion of iron, iron/chromium and iron/nickle alloys.
Aqueous corrosion reactions, which are electrochemical, occur at the metal/liquid interphase. In anaerobic acidic environments the rate of corrosion is frequently controlled by a charge-transfer reaction rather than by the rate of diffusion of reactant to (or from) the interphase. These …

Investigating the use of fiber-reinforced polymer bars in concrete
… use is still somewhat limited. FRP bars are very corrosion resistant and with much of the US infrastructure degrading, the use of FRP bars over conventional steel has been proposed as a fix to this remedy. This thesis looks into the difference between the properties of FRP and steel such as: …
