Origanum Elongatum as a Green Corrosion Inhibitor for C38 Steel in an Acidic Medium
Journal of Failure Analysis and Prevention, 2021The extract of Origanum elongatum Emb. and Maire (OEE) was used as a corrosion inhibitor for C38 steel in 1N HCl medium, the inhibitory effect was studied by different techniques, weight loss and electrochemical measurements. Weight loss measurements indicate a maximum efficiency of 77.50% at a concentration of 1 g/L at 298 K.

Tensile Behavior of Semi-Solid C38 LTT Steel
Solid State Phenomena, 2016The high temperature range for steel semi-solid state makes the experiments particularly challenging. While the response under shear or compression loadings was studied, few results concerned the response under tensile loading. In this paper, an experimental protocol was determined to characterize the uniaxial tensile response of the so-called C38 LTT ...

Use of Omeprazole as Inhibitor for C38 Steel Corrosion in 1.0 M H3PO4 Medium
Journal of Failure Analysis and Prevention, 2020The importance of the use of various drugs as corrosion inhibitors has developed. In this context, the corrosion inhibition of C38 steel in 1.0 M H3PO4 medium by omeprazole has been evaluated by weight loss tests, potentiodynamic polarization and electrochemical impedance spectroscopy measurements.

Kinetic investigation of C38 steel corrosion in concentrated perchloric acid solutions
Materials Chemistry and Physics, 2010The corrosion behaviour of steel at various concentrations of perchloric acid was studied by weight loss method in temperature range from 298 to 323 K. Results obtained show that corrosiveness of acid increases with its concentration and temperature. The logarithm of corrosion rate was plotted against the acid concentration and values of Hammett Ho and

The influence of omeprazole on C38 steel corrosion in HCl solutions (1, 3, 5 M) was evaluated by weight loss and electrochemical techniques. Density-functional theory (DFT) and molecular dynamic (MD) simulations were also used. The weight loss experiment shows that the maximum inhibition efficiency achieved a value of 98.36% in the presence of 5 × 10−3

INVESTIGATION OF ADSORPTION AND INHIBITIVE EFFECT OF CALIXARENE DERIVATIVE NEWLY SYNTHESIZED TOWARDS C38 STEEL IN MOLARHCl [PDF]
Surface Review and Letters, 2009 The focus of this study is to synthesize a new calixarene derivative namely calix[6]arene (C21) and to test its performance as corrosion inhibitor of C38 steel in molar HCl at 308 K. Polarization and weight loss measurements were used. Weight loss tests show that C21 retards until to stop corrosion phenomenon at 5 × 10-5M .

THERMODYNAMIC STUDY OF CORROSION AND INHIBITOR ADSORPTION PROCESSES ONTO C38 STEEL/PIPERAZINES/PHOSPHORIC ACID SYSTEMS [PDF]
Surface Review and Letters, 2009 This paper describes the inhibition effect of 1-benzyl piperazine (P1) and bis(1-benzyl piperazine) thiuram disulfide (P2) towards the corrosion of C38 steel in 5.5 M H 3 PO 4 solution by potentiodynamic polarization and weight loss methods. The influence of inhibitor concentration and temperature on inhibitory behavior of P2 were investigated.
