In this work, the aqueous Lawsonia inermis extract (LI) is investigated as an economic and green deterioration inhibitive formula for steel alloy 4130 in 3.5 wt.% NaCl solutions. The water-based extraction process is considered as one of the cheapest techniques for preparation of active ingredients of natural products. These ingredients play an important role in corrosion mitigation of steel alloy 4130 in saline media. This extract was subjected to three different parameters: inhibitor concentration, rotation speed, and temperature in 3.5 wt.% NaCl solutions. The electrochemical techniques are used to perceive the corrosion behavior, and the obtained results were dedicated to theoretical explorations to assess the features of corrosion inhibition and the adsorption over the steel substrate in 3.5 wt.% NaCl solutions. Affording to the electrochemical techniques of LI showed very promising results against corrosion depending on the inhibitor concentrations. The inhibition efficiency of LI was additionally appraised at three diverse temperatures, and the results disclosed that the inhibition efficiency is decreased. Additionally, the theoretical aspects illuminated that the main active ingredients of LI have a proclivity to coagulate on the steel substrates allowing these areas to paradigm a protecting layer on the steel surfaces. This behavior is in provision of investigational results. Statistical studies were used to examine the consequence of chief constraints (i.e., inhibitor concentration, temperature, and rotation speed) on the inhibition efficiency and the rate of corrosion of steel alloy 4130. The inhibitive effect of LI in contradiction of the corrosion of steel alloy 4130 surfaces is considered by resources of DFT/6-31G(d) calculations. The quantum chemical parameters interrelated to the inhibition efficiency are considered.

“…It is clearly shown from these values that decreasing the weight loss values were leading to suppression of the corrosion rate and increasing the surface coverage area with increasing in inhibitor concentration and the ionic liquid compound is significantly effective against corrosion in sodium chloride solution, which suggested that the adsorption of this compound onto the wrought iron surface from chloride solutions [29][30][31][32].

The interactions between the metal and its environment are responsible for the electrochemical reactions leading to corrosion. To avoid further degradation and in general the appearance of corrosion products, a corrosion inhibitor must be applied on the metallic surface to reduce or prevent the corrosion of exposed metal in a corrosive environment. Corrosion inhibitors are one of the different methods used by conservation-restoration professionals to preserve metallic cultural heritage. The present case study is concerned with preserve and controls the corrosion of the iron entrance door/gate of the clock tower of Muhammad Ali mosque at Salah Ed-din Cairo citadel-Egypt, by using an environmentally friendly Corrosion inhibitor. 1-butyl-1-pyrrolidinium chloride Ionic Liquid is of attentiveness since there has been a growth in ecological consciousness and a variation in guidelines that control the toxicity of systematic corrosion inhibitors. So, the natural products are becoming the main source of environmentally friendly corrosion inhibitors. Furthermost their extracts comprising the required features of the traditional corrosion inhibitors such as oxygen, carbon, nitrogen, and sulfur. These elements are contributed to the adsorption process on the metal surfaces and arrangement of a protective layer, which shields the metal surface against environmental corrosion. Progress of green chemical knowledge compromises a new artificial approach for ionic liquids. These compounds are well-thought-out as new safe corrosion inhibitors which act in different corrosive conditions. Finally, applications of vapor-phase inhibitors and their role of action are recommended in the protection of iron door under study.
