Description

1 TARIFF A corrosion inhibitor material containing plant extracts and oil. Technical Field to Which the Invention Relates 5 The invention involves using plant extracts and oils to protect metal surfaces against corrosion. The invention relates to corrosion inhibitor materials and their production methods. corrosion inhibitor material, hemp seed oil, St. John's wort extract, It contains blackthorn leaf extract and kale extract. 10 State of the Art Corrosion is the deterioration of metals and alloys due to chemical attack or environmental factors. a natural process where they react and try to return to their more stable thermodynamic forms Metal corrosion is a normal and unavoidable process that occurs in certain environments. 15 It can be defined. Corrosion is harmful to the environment and also to human health. It is known that metals and alloys are particularly susceptible to corrosion due to the presence of acids. It shows a high tendency to resist corrosion in acid solutions. It is vulnerable because it can attack the surface of the metal, dissolving its ions and damaging the metal. It can cause corrosion, which results in stable corrosion products during various industrial processes. 20 It occurs in order to create. Traditional applications include inorganic corrosion inhibitors (TICIs) and synthetic ones. Two well-known inhibitors, organic corrosion inhibitors (SOCIs), are used. The currently available commercial TICIs are arsenates, phosphates, chromates, and dichromates. TICIs have high... It can function perfectly for longer periods at higher temperatures and is 25 times better than SOCIs. They are inexpensive; however, TICIs are more potent in acid solutions than 17% hydrochloric acid (HCl). It is insufficient. In addition, phosphates and sulfites are examples of traditional TICIs that are harmful to the environment. Toxic sulfides have a negative impact on biotic communities. TICIs These traditional corrosion prevention methods, described as SOCIs, offer high levels of effectiveness. Although they exhibit corrosion prevention potential, their synthesis and application 30 Due to the toxicity they produce during their production, they cause environmental pollution. 2 Metallic materials, especially steels and aluminum alloys, are used in construction, electrical and It is widely used in electronics fields. These metallic materials are humid. when in contact with the atmosphere, when submerged in fresh or salt water, when planted in the soil or when treated with other aggressive solutions, it is highly resistant to corrosion. It becomes more sensitive. In addition, bacteria, fungi, and algae can grow on the metal surface. 5 This can occur. By adding corrosion-inhibiting organic materials, acid solutions and To reduce the aggressiveness of corrosive aqueous environments and decrease the corrosion rate of materials. It is a well-known type of industrial application. In recent years, metal-based products have been developed using plant extracts rich in active molecules. Research into the development of corrosion inhibitors is increasing. Oils and plant 10 Their extracts are ecological, guaranteeing high corrosion prevention performance at a low cost. It has become a source of inhibitors. These inhibitors, containing oils and plant extracts, are used to treat severe illnesses. It contains no metals or toxic compounds and is biodegradable. Green These natural inhibitors, called inhibitors, are considered environmentally friendly and ecologically sound. It is obtained from plants that are inexpensive, readily available, and easily found. These plants have 15 extracting different crops such as seeds, leaves, roots, bark, and flowers They can be used as corrosion inhibitors by being processed. Plant extracts and oils contain these substances. It contains numerous active compounds such as terpenoids, flavonoids, and bibenzyls, and various active compounds. They contain functional groups. These compounds can be used as adsorption centers. It contains polar groups such as nitrogen and oxygen heteroatoms, and the atoms on the metal surface are 20 These compounds coordinate to form chemical adsorption compounds. These compounds also... It can also inhibit the growth of pathogenic fungi and bacteria, and biological corrosion. It has great application potential in this field. Green inhibitors on metal substrates. the adsorption mechanism on it, physsorption, chemisorption or these two It is classified as a combination of adsorption, mixed type adsorption 25 They are also called inhibitors. Mixed inhibitors are both cathodic and anodic inhibitors. Because they influence the reactions, they provide the highest level of corrosion protection. In the known state of the art, the plant-based patent application numbered TR 2019 / 12244 A corrosion-inhibiting and lubricating composition based on a specific formula is described. The aforementioned Composition contains flaxseed extract and a solution of ethyl acetate and / or HCl in water. 30 This composition is resistant to corrosion of copper, zinc, and aluminum. It prevents damage. It contains chemicals with toxic effects, such as titanium oxide. It contains components and acid. 3 In another known instance of the technique, Seiti and colleagues conducted their research in 2021. In the study, the anticorrosion effect of St. John's wort plant extract on aluminum alloy was investigated. It explains that H. perforatum L. (St. John's wort) water extracts contain 6063 aluminum. The protective role of the alloy against corrosion by acidic solution, at 20°C, both by weight The loss was evaluated using both potentiodynamic polarization techniques. 5 Specifically, the corrosion prevention efficacy was increased with increasing phenolic concentration of the extract, and The highest inhibitory efficiency was found to be 65.7%. In their studies, hydrochloric acid They reported using an acid (HCl) solution. In another known instance of the technique, Yanardag and his colleagues conducted an experiment in 2020. In the study, the extract of the Cannabis Sativa L. (hemp) plant was placed in an aluminum alloy in the environment of 10°C. They have released information regarding its use as a corrosion inhibitor. This The study uses electrochemical impedance spectroscopy and current potential methods. The deposition of aluminum in hemp plant in a 0.5 M sulfuric acid (H2SO4) solution at 298 K. It has been shown to have the potential to prevent corrosion by around 98%. The limitations and inadequacies of current technological solutions make metal surfaces susceptible to corrosion. Traditional applications in protection against inorganic corrosion Toxic effects of inhibitors and synthetic organic corrosion inhibitors, both in humans They are harmful to health and the environment, they are not sustainable, and they are found on metal surfaces. Their inability to prevent bacterial, fungal, and algae growth makes these corrosion inhibitors... 20 chemical components with toxic effects in applications and causing environmental concerns reasons such as the need to use strong acids like hydrochloric and sulfuric acid Therefore, it has become necessary to make improvements in this area.
