Within this study we are concerned by the corrosion inhibition of the essential oil of Lavandula Dentata (EOLD) in carbon steel in 1 M hydrochloric acid solution, the investigation was performed using gravimetric method, Electrochemical Impedance Spectroscopy (EIS) and Potentiodynamic polarization measurements. The results of electrochemical techniques and gravimetric measurements revealed that the EOLD tested as inhibitor leads to a systematic reduction in the kinetics of steel corrosion processes. Potentiodynamic polarization study has shown that EOLD is inhibitor of a cathodic type. The effect of temperature on the corrosion behavior of carbon steel in the presence and absence of EOLD was studied in the temperature range from 303 K to 333 K. The findings about Electrochemical Impedance Spectroscopy revealed a frequency distribution of the capacitance, simulated as constant phase element. Inhibition efficiencies, determined by potentiodynamic polarization, electrochemical impedance spectroscopy and weight loss methods, are in good agreement. The extracted of EOLD, by hydrodistillation, is analyzed by gas chromatography (GC), indeed, this technique of analysis has shown that its major component is: camphor (50.3%). The EOLD inhibitor adsorbed physically on the carbon steel surface obeys the Langmuir adsorption isotherm. The parameters of activation energy was fairly evaluated and discussed in this work.

“…The polar functional groups along with the non-bonding electrons of heteroatoms and pi-electrons of the multiple bonds behave as adsorption centres during interactions between inhibitor and metal surface. The interactions of inhibitors with metal result into their adsorption on the surface which is behaves as barrier for corrosion process [21][22][23][24][25][26][27].…”

Dendrimers are a new class of highly branched, nano-sized, monodisperse macromolecules that have several fascinating physical and chemical characteristics. They are highly soluble in the polar solvents, contain several surface functionality and high surface area which makes them suitable reagents for industrial and biological applications. Recently, several dendrimers have been investigated as effective corrosion and scale inhibitors for metallic and silica corrosion using experimental and theoretical methods. Generally, dendrimers become effective by forming insoluble metal-dendrimer or silica-dendrimer composite on the surface. Their inhibition performance of dendrimers have been measured using several experimental such as weight loss, electrochemical (EIS and PDP) and surface (EDX, SEM and AFM) as well as computation techniques such as molecular dynamics simulation and DFT based quantum chemical calculations. The interactions between metal surface and dendrimers can be explain through some common parameters such as E HOMO , E LUMO , ∆E, electronegativity (χ), hardness (η), softness (σ), dipole moment (µ) and fraction of electron transfer (∆N). Present book chapter deals with detail description on the corrosion inhibition and anti-scaling behaviours of dendrimers for metals and silica in several electrolytic media.
