“…The corrosion loss was quantified by the electrical resistance technique using brass ER‐probes. Details on the resistance probes and the electrical resistance technique were published in . Electrical resistances of the sensing and reference parts of the electrode necessary for calculation of the corrosion loss were recorded by ACD‐03 logger (MetriCorr ApS, Denmark).…”

The survey of 10-century-old illuminations showed that the gold-like areas were made with the use of brass powder. Since this layer has been showing significant damage, it is vital to identify the degradation mechanisms to prevent the priceless manuscript from further deterioration. Degradation of the pseudo-gilded areas, such as darkening of the metal phase and disintegration of the binder, are well visible on the illuminations. The aim of the study was to compare the corrosivity of brass induced by binders using artificial aging tests modelling the conditions for the deposition of illuminated documents in the archives. Egg white, gum Arabic, isinglass and parchment glue were applied throughout the experiments. The samples on brass coupons and electrical resistance probes (ER-probes) were subjected to artificial aging at a high relative humidity and in the air containing acetic acid vapour and the effect of an increased relative humidity on the corrosion behaviour of brass was evaluated. Corrosion depth of the ER-probes versus time was evaluated as well. The results show that the presence of the binder layer on brass increases the corrosion rate of brass at an elevated relative humidity of ambient air. Proteinbased binders resulted in a higher corrosion rate of brass probes compared to that of polysaccharide-based binder -gum Arabic.

“…A corrosion rate of copper in propylene glycol was estimated by means of very precise 50 nm resistometric probes using a Keithley 3706 instrument. The resistometric method and its use are described elsewhere . Three probes were exposed to propylene glycol for 48 h at laboratory temperature, then 24 h at 40 °C and 24 h at 70 °C.…”

The present paper investigated the lifetime of copper nanoparticles in a propylene glycol-based nanofluid. The corrosion behavior of nanoparticles was observed by means of linear polarization resistance, resistometry, transmission electron microscopy, and X-ray photoelectron spectroscopy. Copper nanoparticles were tested in pure propylene glycol with the addition of the inhibitors benztriazole, benzimidazole, and tolyltriazole. The best performance was found with tolyltriazole as it provided some inhibiting efficiency even at higher temperatures, i.e., up to 120 8C. A layer of cuprous oxide was observed on the surface after exposure to propylene glycol, but this oxide was defective on the curved surface of nanoparticles. The corrosion rate of nanoparticles was at least two orders of magnitude greater than the corrosion rate of the compact sample. The lifetime of bare copper nanoparticles was not sufficient for practical purposes even when an inhibitor was used.

The determination of reinforcement corrosion using the electrical resistance method of embedded bars in the concrete beams in laboratory conditions is described in this paper. For comparison, the achieved data from non-destructive measurements were compared to data from subsequent destructive tests when weight losses were recorded for each of the steel bars after their exposure time. Laboratory measurements of the reinforcements were realized particularly for verification of whether the electrical resistance method could be suitable for an in-situ corrosion-evaluation process. The next part of the research was focused on the corrosion simulation of the steel reinforcement in reinforced concrete. The effect of corrosion was simulated by a nonlinear numerical analysis with the program ATENA 3D using corrosion-rate data from a laboratory test. Keywords: corrosion, steel, reinforcement, analysis, numerical modeling V~lanku je opisano dolo~anje korozije palic, vgrajenih v betonske stebre, v laboratorijskih pogojih z uporabo metode elektri~ne upornosti. Izvedena je bila primerjava podatkov iz neporu{nih meritev s podatki iz poru{itvenih testov, ko je bilo izmerjeno zmanj{anje te`e vsake palice po dolo~enem~asu. Laboratorijske meritve palic so bile izvedene predvsem za poskus,~e je metoda elektri~ne upornosti primerna za oceno korozije in situ. Drugi del raziskave je bil usmerjen v simulacijo korozije jeklenih palic v armiranem betonu. Vpliv korozije je bil simuliran z nelinearno numeri~no analizo, s programom ATENA 3D, z uporabo korozijskih podatkov iz laboratorijskega preizkusa.
