“…roughout current years, emerging approaches for shielding of metals in contradiction of decomposition have been a significant area of exploration. Generally, corrosion inhibitors are the greatest common and economic technique for monitoring the corrosion of metals against aggressive chloride media [4][5][6][7]. It has been verified that the organic compounds including atoms such as N, O, P, and S in extra exist in aromatic rings and binary or tripartite bonds.…”

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.

“…Generally, microorganisms tend to create biofilms on a widespread variety of metallic and non-metallic structures by using extracellular polymeric matters to entrench sessile cells [1][2][3][4][5]. The biofilms afford surroundings encouraging to the manifestation of microbial corrosion in several production sectors [6][7][8]. Microbial corrosion comprises corrosion initiated by microorganisms in addition to corrosion by another pre-existing corrosion agent that is accelerated by microorganisms.…”

Microbial corrosion has developed a foremost problematic in the oil and gas industrial field. This problem is by reason of the continual usage of water swamping in promoting oil recovery. This water moistens the walls of oil pipelines. Microbial corrosion is also present in other industries such as nuclear power reactors and in most hydropower applications. Increased corporate infrastructure also leads to increased microbial corrosion. Sulfate Reducing Bacteria (SRB) is considered as the main kind of bacterial which cause of pipeline corrosion. Because of microbial deterioration is not understood, until recently, there is no clear mechanism to explain why and how microbial corrosion occurs because of the complexity of this area. The new theory of biocatalytic cathodic sulfate reduction is bio-electrochemistry based. In this theory, the bioenergetics can explain why microbial corrosion occurs, while the extracellular electron transference theory is capable of explain how microbial corrosion happens. The microbial corrosion can be caused by nitrate reducing bacteria, which led to an analogous biocatalytic cathodic nitrate reduction theory. The electron mediator assessment intended to validate the extracellular electron transference progression which anticipated in biocatalytic cathodic sulphate reduction. The electron mediators like riboflavin and flavin adenine dinucleotide were accomplished of hastening the microbial corrosion by indorsing electron transport flanked by an iron surface and a biofilm. In case of deficient in organic carbon, the elemental iron substituted the organic carbons as an energy source/electron donor for SRB to get their conservation energy. Under unembellished undernourishment of organic carbon, the largest pit depth was accomplished, which was consistent with the estimate of biocatalytic cathodic sulphate reduction. The developing request and crucial necessity in oil and gas industry is to find an effectual method to avoid and/or mitigate microbial corrosion at a rational cost.

“…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]. Table 1: shows results of XRD analysis of corrosion products that formed on the iron surface.…”

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.
