Abstract

In this research a nano polymeric coating has been prepared to be used for the protection of the external surface of oil pipelines (medium carbon steel (CK50)) from corrosion in salt water (3.6% NaCl) . This coating is reinforced by inorganic (nano and micro) additives to apply a high resistance against chemicals and salts. These oxides protect the epoxy resin from degradation by preventing the epoxy molecules and active functional groups from absorbing ultraviolet light in the range (290-315) nm strongly.This coating is also resistant to the high and low temperatures, humidity, scratch and water. This coating was prepared from the reaction of 2-[[4-[2-[4-(Oxiran-2-ylmethoxy) phenyl] propan-2-yl] phenoxy] methyl] oxirane (Diglycidyl Ether of Bisphenol A) and the hardener (EDA). The mixing ratio of the two parts was (4:1). Reinforced with inorganic (nano and micro) additives such as titanium dioxide (TiO2) and zinc oxide (ZnO) which have been used as an anticorrosion. These additives are non-toxic, thermally stable and have a high degree of the miscibility with epoxy. The weight percentages of the mixing are (0 and 10 % wt). The corrosion rate results show that using (nano and micro) coating give good results in increasing the corrosion resistance compared with the (non additives) epoxy.This coating was characterized using different spectroscopic methods (FT-IR, UV/Vis). Several tests were conducted ,including differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) , mechanical tests and evaluation of corrosion resistance was made by using static potential test.

Abstract

The effect of introducing Al2O3 and CuO nano particles on thephysical properties of sintered Ti-C based materials has been studied.Titanium and carbon elemental powders have been mixed with nanoparticlesof Al2O3 and CuO to produce composites of Ti-C/ceramics at 1100 °C. TheXRD results show that for different amount of mixed nanoparticles, TiC, TiO2,and some rest of the reacted powders are the most dominant stable phases. Interms of physical properties, the results show that the raised Al2O3 percentageleads to gradually increase in apparent density of the sintered mixture ascompared with the purely prepared TiC. Moreover, porosity and waterabsorption decrease with increasing Al2O3 percentage. On the other side,adding CuO to the sintered mixture causes in decreasing the apparent density.Furthermore, it was observed that CuO creates much porosity and increasewater absorption of the sintered mixture.
