In this study, the corrosion performance of platinum/ruthenium/nitrogen doped diamond-like carbon (PtRuN-DLC) thin films deposited on p-Si substrates using a DCmagnetron sputtering deposition system in a 0.1M NaCl solution was investigated using potentiodynamic polarization test in terms of film thickness. Theeffect of thefilmthickness on the chemical composition, bonding structure, surfacemorp...

LI, CHONG, Ph.D., June 2009, Chemical Engineering Effect of Corrosion Inhibitor on Water Wetting and Carbon Dioxide Corrosion In Oil-Water Two-Phase Flow (198 pp.) Director of Dissertation: Srdjan Nesic The internal corrosion of flowlines and pipelines made from carbon steel is encountered in the oil and gas industry. The corrosion process is primarily associated with the presence of free water...

The inhibitive effect of congo red was examined as corrosion inhibitor for the corrosion of zinc in 1N HCl by conventional weight loss and gasometric methods. Results obtained show that congo red exhibited high inhibition efficiencies. The inhibition efficiency was found to increase with increase in the inhibitor concentration. The adsorption of the inhibitor molecules on the zinc metal surface...

The anodising process parameters (voltage, temperature, and electrolyte) control the morphology chemical composition of resulting anodic oxide film by altering balance between growth dissolution reactions. porosity is reduced addition tartaric acid to a sulfuric electrolyte, while at elevated temperatures enhances dissolution, leading wider pores rougher surfaces. No significant changes in as f...

The electrical resistance and polarization effect of cement paste containing reinforcement were tested to research the anti-corrosion properties steel bars in paste. Moreover, microstructure composition passivation film rust on studied. water–cement ratio this study was 0.3, with 0.5% NaCl, 1% NaNO2, Benzotriazole, an assembly unit NaNO2 + Benzotriazole by mass added provide a chloride environm...

This paper studies the corrosion behavior of B10 copper-nickel alloy in marine environment. Accelerated degradation test under marine environmental conditions was designed and performed based on the accelerated testing principle and the corrosion degradation mechanism. With the prolongation of marine corrosion time, the thickness of Cu₂O film increased gradually. Its corrosion product was Cu₂(O...

this work is aimed to evaluate the role of nanoclay in the protective performance of an eco-friendly silane sol-gel layer applied on mild steel substrate in 0.1m sodium chloride solution. at the first step, the effect of ph of the silane solution, consisting of a mixture of γ-glycidoxypropiltrimethoxysilane and methyltriethoxysilane and tetraethoxysilane, on the coating performance was evaluate...

The corrosion resistance of SS 18/8 in natural sea water, presence an inhibitor named Thiourea-Zn2+ has been evaluated. Weight loss method, polarization study and AC impedance spectra have employed to evaluate the alloy system. method reveals that system offers a maximum inhibition efficiency 95% controlling water. Synergism parameters are found be greater than 1, confirming synergistic effect ...

The inherent safety and low cost of aqueous aluminum-air (Al-air) batteries have attracted significant attention. However, their lifespan is constrained due to the formation passive layers severe self-corrosion Al anode. This work addresses anode issues using an innovative design strategy by adding vanadate nanoclay modify interaction electrolyte. results shown that each vanadate, nanoclay, a h...
