Study the Functional Response of Nitrocellulose and Sodium Silicate Reinforced by Magnesium Oxide Particles Composites Towards

Abstract

To determine the best composite coatings for inhibiting the metallic corrosion in the oil pipelines,the Surface Hardness,Wear Resistance,Adhesion Strength, Electrochemical Corrosion Resistance by Polarization method (Tafel), Thermal Conductivity and Atomic Force Microscopy(AFM),were applied in this work by using two groups of composite coatings.The first group is nitrocellulose reinforced by nano Powder of MgO at (0.0, 1,3 and5%),and Micro Powder of MgO by weight percentages (0.0,3,5and7%).and The Second represented by sodium silicate reinforced by nano powder of MgO only by applied the same percentages above. The results showed that there was high improvement in the Tribological,adhesion and thermal properties of composite coatings,with clear superiority for composite coatings of nitro cellulose on composite coatings of sodium silicate when compared to non-reinforced coatings to provide a protective layer for steel from hazard of corrosion
