Modified nanosilica powder was prepared with a sol-gel method using a tetraethoxysilane (TEOS) and γ-amino propyltriethoxysilane (APTES) mixture as the starting materials and ethanol as solvent, followed by the addition of water. The xerogels obtained after drying at 125 °C had an average particle size of 225 nm and were calcinated in a furnace for...

Galvanized steel pipes are the main material in the implementation of domestic water distribution networks throughout Iraq. To study the variables affecting their corrosion, mathematical relationship for the calculation of corrosion rate was derived in terms of dissolved oxygen concentration, flow velocity and temperature based on the principles of...

The use of nano alumina thin film by hybrid sol-gel route to protect steel from high-temperature oxidation is limited due to the low thermal stability of this coat. In this work, study has been conducted to minimize this effect. The chemical compositions of solid gel (xerogel) obtained from normal alumina hybrid sol-gel were thermally varied, and t...

An overall mathematical model for copper pipe corrosion in flowing water was derived based on mass transfer fundamentals where we introduced the effects of boundary layer velocity, bulk flow velocity and the surface oxide protective film on the corrosion rate. A set of experiments were conducted in a straight 10mm diameter copper pipe, flow of wate...

The degradation of a number of high-temperature alloys in air-2.13% chlorine at 900°C under isothermal conditions has been studied. Despite the formation of a Cr203 or Al2O3 scale, all the alloys underwent considerable corrosion, which involved penetration of chlorine-containing species through the scale to the scale-alloy interface, and reaction o...
