Galvanic couples traditionally used for the evaluation of atmospheric corrosivity are constant monitoring sensors whose output correlates with deposition sea salt. This report provides conversion methodology needed to monitor real-time airborne salinity. The was validated by wireless observations made in two Japanese coastal areas, where a remarkable increase salt revealed rapid contamination. ...

The effects of different Ce content on the microstructure and corrosion resistance Al-5Mg-3Zn-1Cu alloy in metal mold gravity casting were studied this paper. was characterized by scanning electron microscope (SEM) X-Ray diffractometer (XRD). corrosivity all alloys 3.5 wt.%NaCl solution electrochemical immersion techniques. results show that is mainly composed α-Al, T phase, Al2Cu phase. can re...

We studied atmospheric corrosion on Rapa Nui Island, using galvanized and non-galvanized SAE 1020 steel samples exposed racks. also added Charpy of both materials to directly determine the effect rate these materials' impact toughness. The results indicated a correlation between toughness loss in materials. In study, we could demonstrate from increased insular population growth contaminants whi...

Cr-free paints applied on different aluminum alloys were exposed for 5 years at atmospheric weathering sites worldwide. By image analysis, the extent, and type of corrosion (filiform or blistering) determined after 1, 2, years. In that way, it was possible to rank systems as a function their resistance corrosion. The kinetics degradation each system all also determined. From results, is shown d...

At present, there are few studies on microbial corrosion of magnesium anode materials that provide protection for oil pipelines in tidal flat environment. In view an abnormal failure anodes a mud environment, the influence change water content beach AZ31B by sulfate-reducing prokaryote (SRP) was investigated electrochemical methods, weight loss and surface analysis techniques. SRP can grow well...

Abstract The corrosivity of atmospheres in Europe has changed significantly recent decades. For the Federal Republic Germany, no current values for corrosion rate based on 1‐year atmospheric exposure standard specimens can be found scientific literature after 2000. This paper presents results from a field study Berlin metropolitan area and Helgoland 2016. Based specimens, corresponding category...
