Resumen

The inhibition effects of A-Mo inhibitor on corrosion of carbon steel in 55% LiBr solution were investigated using cyclic potentiodynamic polarization curves EIS experiments, Mott-Schottky analysis, SEM, EDAX and XRD methods. The results revealed that A-Mo inhibitor was capable of inhibiting the corrosion of carbon steel in 55%LiBr solution, exhibiting high inhibition efficiencies around 99.7%. A-Mo inhibitor promoted the formation of a protective passive film composed of Fe, Mo and O elements. The passive film improved the electrochemistry performance and enhanced corrosion resistance of carb

Resumen

Inhibitor is a substance that is added to the corrosive media to inhibit corrosion rate. Organic inhibitors are preferred to inorganic ones since they are environmentally friendly. One of the organic compounds which is rarely reported as a corrosion inhibitor isMyrmecodia Pendans. The organic compounds can be adsorbed on the metal surface and block the active surface to reduce the rate of corrosion. In this study, the used pipe was carbon steel API 5L Grade B with 3.5% NaCl solution as the corrosion medium. The objective of this research was to analyze the inhibition mechanismMyrmecodia Pendan

The synergism of CeCl3 (Ce) with cysteine (Cys) on the corrosion of P110 carbon steel in 3% NaCl solutions was investigated by electrochemical methods and surface analysis. The results showed that CeCl3 and cysteine do little to inhibit the corrosion of carbon steel, but the combination of CeCl3 with cysteine has obvious synergistic effect on the corrosion of carbon steel and the corrosion inhibition efficiency was improved significantly. The potentiodynamic polarization curves indicated that the mixture of CeCl3 and cysteine acts as a cathodic inhibitor. Scanning electron microscope (SEM) and

Corrosion inhibitors are vital in industry for protection and prevention of surfaces from corrosion attack. There is need to have green inhibitors that are environmentally friendly and not hazardous to use. Extract from stem of banana (Musa species: Musa-Acuminata) was considered as green inhibitors. Extracts from the stem of banana was subjected to physico-chemical, phytochemical screening and corrosion test using gravimetric measurement with a low carbon steel flat bar coupon.

Resumen

In recent years more attention is paid to high-efficiency and nontoxic corrosion inhibitor. Synergistic inhibition is an effective means to improve the inhibitive force of inhibitor. The aim of this work is to attempt to find out inhibition mechanism and synergistic effect of Lysozyme (LYZ) and vitamin B1 (VB1) and to diversify the application of inhibitor in acidic medium. The corrosion inhibition effect of LYZ and VB1 for carbon steel specimens in 0.5 mol•L-1 sulphuric acid solution have been investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) method

Resumen

Polymers are materials composed of macromolecules characterized by duplicates of smaller molecules that are covalently bonded together to provide a set of properties. Corrosion inhibition by such compounds is usually attributed to their adsorption on the metal-solution interface. The inhibition effect of different sizes of polyvinylpyrrolidone (PVP) on the corrosion of carbon steel (C-steel) in solutions of perchloric acid was investigated. The inhibition efficiency increases as the size of the inhibitor and its concentration increases, but decreases as the temperature increases and can reach

Corrosion is the reaction between the material and the environment that cause degradation of the material. Corrosion reduces the essential properties of materials such as strength, appearance, toughness and life expectancy. Carbon steels are composed of a mixture of metallic iron and carbon and being used extensively in every sector due to good mechanical properties and good cost. However, carbon steel are every susceptible to corrosion attack especially in corrosive environment. The use of inhibitors is one of the best options to protect against corrosion on metals and alloys especially in a
