Opis:
Corrosion of metals is the gradual destruction of metal under the impact of environmental factors. Chemical or electrochemical processes on the surface of the metal cause irreversible changes in the structure of the metal. To prevent this, during storage or transport, the surfaces of metal elements must be protected against environmental factors, which include: high air humidity, acid rain and variable temperature. These factors accelerate the corrosion process, which cannot be eliminated, but can be reduced by protecting metal elements with e.g. protective oils. Some metals have the ability to passivate, which is a natural protective agent that prevents corrosion. It consists in the formation of an oxide of this metal on the metal surface. Where there is no natural protection against corrosion, protective measures must be used. This paper presents the technology for the production of protective oil for temporary protection against corrosion. The innovation of this project is that the oil will form a thin, well adhering protective layer on the metal surface, which can be easily removed. It is characterised by very low viscosity and low dripping time. It is possible to achieve by using proper base oil with carefully selected anti-corrosion additives. Based on the standard PN-75/C-04154 Petroleum products. Rust protection by metal preservatives the humidity cabinet test method, corrosion tests were carried out. The paper presents the results of a humidity cabinet test for an oil mixture based on deeply refined base oil and properly selected refining additives. The test results confirmed very good anti-corrosive properties of the developed oil due to the use of a corrosion inhibitor and an oxidation inhibitor. The thickness of the protective layer formed on the metal surface was calculated based on a mathematical formula. The resulting layer forms a thin oil film, easy to remove and protecting the metal surface from corrosion.

Opis:
Cr-Ni-Mo stainless steels are susceptible to the pitting in aggressive chloride environments. One of the possible ways for the influence of their corrosion behavior is the use of inhibitors as the chemical modification of the environment. The resistance of AISI 316Ti stainless steel to the pitting with/without the inorganic inhibitor was tested by two independent corrosion tests: 24-hours exposure immersion and potentiodynamic polarization test. Both tests were carried out in 1M chloride acidic solution with/without 0.1M molybdate inhibitor at room temperature. Results of immersion tests were evaluated by the corrosion rates calculated from corrosion losses and by the morphology of the pitting. Potentiodynamic polarization curves were evaluated by the pitting potentials.

Opis:
This study presents the deployment of antepsin (sucralfate) as corrosion inhibitor of mild steel in H2SO4 medium. Chemical (gravimetric) and electrochemical (potentiodynamic polarization and electrochemical impedance spectroscopy) techniques were used in the corrosion control investigation. The antepsin drug was characterized by gas chromatography mass spectrophotometer (GCMS) and Fourier transform infrared (FTIR) spectroscopy. Effects of inhibitor concentration, temperature and time on weight loss, corrosion rate, inhibition efficiency and degree of surface coverage were examined. Thermodynamic and adsorption properties of the corrosion inhibition process were determined. Inhibition efficiency was optimized using central composite design tool of Design Expert software version 12. Potentiodynamic polarization and electrochemical impedance spectroscopy were employed to determine the type and effectiveness of the inhibitor. As a confirmatory test, scanning electron microscopy (SEM) was employed to examine the surface morphology of the mild steel samples. Analysis of the results showed that major constituents of antepsin include tetradecanoate, metronidazole, hexadecanoic acid, methyl ester and 11-octadecenoic acid. The predominant functional groups include; C=O stretch, C-H bend and symmetric and asymmetric =C-O-C. Adsorption of the molecules of antepsin on the surface of the mild steel was spontaneous and occurred in agreement with physical adsorption. A quadratic model adequately described the relationship between inhibition efficiency and corrosion control variables of concentration of the inhibitor, temperature and time. Optimum inhibition efficiency of antepsin was obtained as 86.75%. Chemical and electrochemical results agreed that antepsin is suitable for corrosion control of mild steel in H2SO4 solution. Antepsin acted as mixed-type inhibitor (controlled both cathodic and anodic reactions).

Opis:
The influence of the concentration of sodium molybdate(VI) on the corrosion of S235 carbon steel in solutions contained chloride and nitrate(V) ions have been studied. For the research purpose a weight loss method has been used. It can be concluded that the addition of Na2MoO4 to the aggressive environment reduces the weight loss of the sample. Inhibition efficiency and corrosion rate have been calculated. The efficiency inhibition of corrosion has been about 93%. It has been found that the corrosion rate of S235 steel, in a solution containing 100 mM sodium molybdate (VI) was about 14 times lower than in the solution without inhibitor. Therefore, the examined compound was an effective inhibitor of the corrosion of S235 carbon steel.

Opis:
Point of present exploration was to figure out the anticorrosion activity of Acacia Cyanophylla (Saligna leaves) extract on the corrosion of mild steel in dilute sulfuric acid medium, using weight loss measurements and electrochemical impedance spectroscopy. The result of the study revealed that the extract act as a potent inhibitor on mild steel in acid medium. The increase in inhibitor concentration and immersion time showed a positive effect on inhibition efficiency. EIS exhibited one capacitive loop which indicates that the corrosion reaction is controlled by charge transfer process. The increase of phase shift (n) in presence of (ACLE) lower surface roughness. This change reveals the adsorption of the inhibitor compound on the steel surface. According to the results of weight loss measurements, the adsorption of the extract on the steel surface can be described by the Langmuir isotherm. The inhibition mechanism of (ACLE) molecules involves physical interaction between the inhibitor and metal surface. Additionally, Protective film formation against acid attack was confirmed by FT-IR and AFM techniques.

Opis:
Corrosion is a global menace which has imparted the world economy greatly. One of the solutions proffered to these challenges is the use of inhibitors. Several natural inhibitors have been used to protect engineering materials from corroding. This research is focused on investigating the inhibitive properties of Hura crepitans seed (HCS) on Duplex Stainless Steel 2101 (DSS2101) in H2SO4. The selected plant part was subjected to characterization to determine the presence of organic anti-corrosion agents present. From the result, phytochemicals such as saponin, tannins, steroid and flavonoids were observed. The presence of the organic group accounted for the inhibitive efficiency recorded in the environment. The polarization studies revealed that generally the inhibitor produced from seed extract of Hura crepitans, improved the corrosion resistance of DSS2101 in 0.5M H2SO4. The optimum corrosion inhibitor efficiency was observed at 0.2% inhibitors in 0.5M H2SO4 for 2101DSS.

Opis:
This study investigated the characterization of Ficus exasperata extract and the optimization of the process variables on inhibition of mild steel in seawater environment. Box Behnken Design was employed to examine the influence of three process variables: Temperature: 25-29 °C; Time: 3 – 6 days; Inhibitor concentration: 1-5 v/v. Phytochemical screening of the extract was done. The physicochemical constituents of the seawater were also determined. The experimental data was statistically determined and Scanning Electron Microscope (SEM) was used to characterize the mild steel. The result of the phytochemical screening of the Ficus exasperata plant extract (FEPE) showed the presence of contain inhibitive constituents: alkaloids, tannins, saponins, flavonoids and glycosides. The highest inhibition efficiency of 86.31% at a temperature of 29 ℃ for 6days at an inhibition concentration of 3v/v was observed from the experimental run. The optimal process levels of time: 5.74 days, temperature: 27.95 ℃ and inhibitor concentration: 2.90v/v, gave 87.52% as its inhibition efficiency. The result of the SEM from the optimal process level validated showed that more passive film was formed which can be attributed to the adsorption of the Ficus exasperata extract. It can be concluded that the Ficus exasperata was a good eco-friendly inhibitor.

Opis:
The inhibitive action of the ethanol extract of oil from Picralima nitida leaf, towards acid corrosion of zinc, is tested using weight loss, and thermometry methods. It was found that the extract acted as a good corrosion inhibitor for zinc corrosion in 0.5 M H2SO4 solution. The inhibitive action of the extract was discussed in view of Langmuir adsorption isotherm. It was revealed that the adsorption of the extract on zinc surface is governed by spontaneous process. The inhibition efficiency (IE) increases in line with corresponding increase in extract concentration. The temperature effect of the corrosion inhibition on the IE was studied. Revelation from the studies indicates that the presence of extract increases the activation energy of the corrosion reaction. Furthermore, from the calculated thermodynamic parameters, it was observed that Picralima nitida extract provides a good protection to zinc against pitting corrosion in chloride ion containing solutions.

The inhibition of X80 carbon steel corrosion in 1 M HCl solution by dexketoprofen (DKP) was studied using weight loss (WL), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP) and scanning electron microscopy (SEM) techniques. The results indicated that DKP acts by way of adsorption as an effective protective inhibitor in the aggressive acid medium. The inhibition efficiency of DKP increased with concentration but was lower at higher temperature. The results of potentiodynamic polarization showed that DKP molecule behaved as a mixed type inhibitor by reducing both the anodic and the cathodic electrochemical reactions. Dexketoprofen was adsorbed on the X80 steel surface in accordance with Langmuir adsorption isotherm. SEM analyses supported formation of protective film on the X80 steel in the presence of DKP.

Opis:
The main objective of this paper is to present a comparison of the corrosion inhibiting effect of thiourea and THAM (tri(hydroxymethyl)aminomethane) on carbon steel samples immersed in calcium chloride solutions. The testing has shown that to inhibit the corrosive action of the calcium chloride solution, the thiourea solution can be successfully replaced by the THAM solution. The study was performed with the use of st3s, structural and reinforcing steel. In the case of st3s steel samples, the application of the 0.01% THAM solution causes a decrease of its weight loss by about 60%. The application of a 10-times stronger THAM solution causes an increase of the corrosion inhibition on the tested samples by about 20%. A combined protective action of the thiourea and THAM solutions brings about an increase of the corrosion process inhibition by about 70% both for the st3s and the structural samples. The 0.01% and 0.1% THAM solutions applied to inhibit the corrosion process on structural samples cause an increase of the corrosion protection by about 50% and 15% respectively.

This research investigated the inhibition behavior of Spondias mombin leaf (SML) extracts in 0.1 M HCl solution on mild steel at various concentrations and temperatures. The result reveals that the inhibition efficiency of the extract on the mild steel sheet increases with increasing concentration of the extract and decreases with increase in temperature. Therefore, the adsorption mechanism of the extract on the mild steel surface is physical. Calculated Correlation Coefficient (R2) values show that the process follows a Freundlich adsorption isotherm. The proposed temperature coefficient equation of adsorption mechanism was found to be appropriate.
