Abstract Unprotected copper conductors are prone to oxidation and corrosion, especially when in contact with salt water or at high temperature. In this study, we compared commercially available coating graphene oxide plasma-enhanced chemical vapor deposition (PECVD) coated wires terms of antioxidation anticorrosion protection. Samples were subjected aging tests a spray chamber. Thereafter, both...

The presented investigations demonstrate the corrosion behavior and protective ability of hybrid zinc coatings specially designed for combined protection low-carbon steel from localized biofouling. Polymer-modified copper oxide (CuO) nanoparticles as widely used classic biocide are applied this purpose, being simultaneously electrodeposited with electrolytic bath. is evaluated in a model corros...

Geothermal energy is accredited as a flexible, controllable and green source of energy. Heat exchangers (HXs) are one the most critical components geothermal power plant due to corrosion scaling phenomena. Hence, improvements in antiscaling anticorrosion properties well heat transfer performance HX materials will lead smaller, more efficient less costly systems. EU H2020 GeoHex project relies o...

One of the main methods for monitoring technical condition navigation locks gates is to determine amount corrosion wear their elements using ultrasonic thickness measurement. This diagnostic operation performed at least once every five years. In accordance with methodology, control requires removal protective coating in measurement area. At same time, there no possibility a full restoration coa...

Layered double hydroxides (LDH) are lamellar structures with positively charged laminates and charge-compensating interlayer anions. The ion-exchange capacity of LDHs makes them as promising hosts for corrosion inhibitor anions stimulus-responsive release self-healing anticorrosion. In the current work, loaded two different inhibitors (nitrogen oxides benzotriazole) were evaluated their autonom...

The electrochemical synthesis of poly(N-phenylpyrrole) film was achieved on pretreated iron and platinum electrodes in acetonitrile solutions containing 0.1 M N-phenylpyrrole as the monomer and 0.1 M tetrabutylammonium trifluoromethane sulfonate (Bu4NCF3SO3) as the supporting-salt. The results showed that a surface treatment by 10 % aqueous nitric acid inhibits iron dissolution without preventi...

The paper presents the impedance measurement method using a real-life step pulse as a perturbation signal and Laplace transformation as a tool for analyzing the response of the object under test. The method is addressed to explore different technical object (like anticorrosion coatings, gas sensors, ceramics, dielectrics biological tissues etc.) when the measurement time cannot be long. The pre...
