Corrosion is a phenomenon that strongly affects many industries. Everything related to metallurgy, shipbuilding, or the oil industry negatively affected by corrosion processes. This big problem, because number of industrial accidents due reaches more than 75%. Therefore, in this work, effectiveness inhibition processes mineralized water-oil environments was investigated detail. The main goal article study regularity media different composition and at temperature regimes for effective selection mechanism type inhibitor. An method reducing impact today use inhibitors. expedient not only from point view action, but also economic expediency. Inhibitors are added corrosive order stop reduce They can be used as protective barriers form layer, absorbers prevent oxidation In future, inhibitor selected depending on metal conditions reactions responsible occurrence course corrosion. Currently, inhibitors recognized most way intensity destruction structures. At same time, it impossible obtain universal meets requirements high efficiency, manufacturability, toxicological safety, time obtained an economically feasible way. Among various inhibitors, organic ones have shown their protecting low-alloy steels equipment. Metal samples St20 steel, widely manufacture pipelines production equipment, were corroding materials study. pH changed adding solution acetic acid. degree determined massometric method. volume test 150 cm3, adjusted with 5% acid solution.

However, found increase content carboxylic acids, does affect any Arguably, alkylamidazoline showed protection room temperature, contrast studies temperatures.

In this paper, four quinoline quaternary ammonium salts were synthesized using quaternization reaction, which benzyl quinolion (BQL), naphthylmethyl quinolinium chloride (NQL), benzyl-8-hydroxy (BHQ) and 8-hydroxy (NHQ). The corrosion inhibition properties of the derivatives as inhibitors on P110 steel in 20% HCl solution at 60°C different concentrations investigated by weight loss electrochemical measurements. results showed that concentration inhibitor increases, rate decreased efficiency improved. Among various same concentration, their efficiencies can be ranked from lowest to highest follows: QL(quinoline)<8-HQ(8-hydroxyquinoline)

Abstract Self‐repairing coatings have received widespread attention due to their ability repair damaged surfaces. However, film‐forming molecules can only be fixed on the metal surface through relatively weak physical and chemical adsorption. This drawback limits its self‐repairing ability. Here, a mode‐switchable TENG (MS‐TENG) is developed, which has switch between AC DC outputs as an adjustable charge source for coatings. Besides normal sector electrodes of rotational TENG, MS‐TENG special design external (small extension rotator inner/outer orbit stator) achieves accumulation excitation circuit output air breakdown with advantage complete release accumulated charges. Compared traditional current been improved. In addition, process occurs in electrode framework independent body. Therefore, negative impact suppressed. Finally, used achieve rapid electrostatic adsorption charged injection. effectively improves performance coatings, corrosion inhibition rate 96.9%.
