in this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). the loaded mesoporous silica was dispersed in an epoxy matrix. the composite was then coated on the mild steel plate. results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate was better than the one without molybdate or neat epoxy. on the other hand, e...

nano-films consisting of an alternating sequence of positively and negatively charged polyelectrolyteshave been prepared by means of the electrostatic layer-by-layer sequential assembly technique on mildsteels. the mild steels were pretreated electrochemically to modify the mild steel surface. the modificationof the mild steel surface resulted in increasing the adhesion of the obtained nano-fil...

Corrosion behavior of mild steel in chloride contaminated alkaline solution has been studied for the period up to 100days. Saturated Calcium hydroxide solution was used as alkaline solution and 0.5M NaCl solution was used to accelerate mild steel corrosion. The Charge transfer resistance Rct, Current density Icorr and inhibition efficiency values were obtained from tafel polarization and electr...

the idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. in addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. a useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...

Hydroxyethyl cellulose (HEC) was studied as corrosion inhibitor for mild steel and aluminium in 0.5 M H2SO4 solution using weight loss and electrochemical techniques. The results revealed that HEC inhibited corrosion of mild steel and aluminium in sulphuric acid environment. Inhibition efficiency was found to depend on concentration of the inhibitor. Impedance results revealed that HEC was adso...

2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...

The continuous search for better corrosion inhibitors, due to vast differences in the media encountered in industry remains a focal point in corrosion control. The use of organic compounds to inhibit corrosion has assumed great significance due to their application in preventing corrosion under various corrosive environments. These compounds have great potential to inhibit aqueous corrosion due...

In the context of highly efficient, non-toxic and natural organic corrosion inhibitors, Phyllogorgia dilatata was studied as an anticorrosive for mild steel in acid medium. The marine octocoral crude extract (PDCE) was characterized and analyzed by LC-HRMS, revealing the presence of 16 different organic molecules. The corrosion inhibition was evaluated via weight loss study and electrochemical ...

The impact of pre-corrosion on the performance an imidazoline-based corrosion inhibitor was evaluated with respect to inhibition uniform and localised in CO2-environments. Corrosion protection found be a function two factors, adsorption/film formation presence products. This effect most significant continuous FeCO3-rich layer high coverage steel surface, resulting only providing ?25 % overall a...

A new experimental method was applied in in situ corrosion monitoring of mild steel Q235 under alternate wet-dry conditions. The thickness of the electrolyte film during the wet cycle was monitored by a high-precision balance with a sensibility of 0.1 mg. At the same time, an electrochemical impedance technique was employed to study the effect of film thickness on corrosion rates. Experimental ...
