... showed a negligible influence on both uniform and localized TLC rates. At a high CO 2 content, the formation of a protective FeCO 3 layer decreased the TLC rate, especially at lower water condensation rates. Nevertheless, the risk of localized corrosion at high and medium water condensation rates...

... demonstrated that electrochemical noise associated with wavelet transform analysis, particularly wavelet scalograms, is an effective tool for monitoring localized corrosion of welded carbon steel. INTRODUCTION It is well known that weld corrosion can be caused by any of a number of factors associated...

... Steel (UNS S39274) were evaluated. Localized corrosion was observed in S41426 at conditions higher than 200ppm O 2 (0.026 bar O 2 partial pressure) condition. On the other hand, S82551 and S39274 showed good corrosion resistance in the same condition. As for S82551, it suffered from localized...

The test program accounts for different levels of chlorides, dissolved oxygen, brine pH, and temperature, in order to reproduce corrosion in the environment(s...

... cause severe localized corrosion of aluminum alloys. The corrosion behavior was studied at multiple temperatures in different corrosion inhibitors using different concentrations. Corrosion inhibitor VCI-A, VCI-B, VCI-C, and VCI-D at 2.5-3.0% dosage showed excellent corrosion protection. VCI-A, VCI-C...

... at this location). The moisture level distribution in the soil, with a smaller anodic area, limit the current density at the cathode with a maximum current density of about -20 mA/m², i.e. a reduction of the local corrosion rate of 23 µm/y. In Ruffiac loam, a similar behavior was observed as presented in Figure 7...
