Metal corrosion is one of the most challenging problems facing industries. Using corrosion inhibitors is one reasonable approach to protecting metal surfaces. Due to the toxicity of industrial corrosion inhibitors, researchers are continuously searching for green, economical, and friendly alternatives. The present study focuses on the application of Terminalia catappa leaf extract to mitigate the corrosion of concrete reinforcing steel in a simulated seawater environment. The dry product from the Terminalia catappa leaf extraction process was determined to have amino functional groups in polyphenols. Polarization results demonstrate that the corrosion current density decreases from 8.87 A/cm2 (for samples soaked in blank solution) to 5.12 µA/cm2 when adding the optimal concentration of 0.004% of Terminalia catappa leaf extract. 3.5% NaCl solution. Electrochemical impedance spectroscopy (EIS) analysis showed that the inhibition efficiency reached over 90% at this concentration after 24 hours of soaking.

“….-The most power full tool to produce an environmentally friendly coating is the sol-gel process which can replace the CCC coating with CAA. 37 Inorganic and organic hybrid constituents show an important functional material, where they find applications in wide-area like silver metallic reflectors utilized in laser cavities which are dip-coated with a hybrid silica-based defensive layer and in medical applications. 38 These coatings are called smart coatings because of the improved mechanical properties, 39 but the process has the limitations the electrical and optical property will be changed.…”

The current study focuses on the effect of the different ceramic reinforcement on the aluminium composite. The pros and cons of AMMCs are studied. In SiC reinforced composite’s wear resistance, tensile strength and hardness will be improved, as it acts as an obstacle to the dislocation of atoms. B4C reinforced composites form more pores and agglomeration by the increase in B4C content however the hardness improves at the expense of ductility. TiC reinforced composite’s interfacial bonding is good below 600 °C and the coefficient of thermal expansion reduces by increasing TiC weight percentage also mechanical properties like tensile and compressive strength improves. Al2O3 reinforcement will make grains finer hence adding Al2O3 improves the mechanical properties of the composite and it doesn’t react with the matrix at high temperature. ZrO2 reinforcement will improve the hardness and wear resistance although primary wear happens due to micro-cutting and oxidation. As mentioned each reinforcement has both advantages and disadvantages, based on the application required reinforcement will be selected.
