A Micro-Raman Spectroscopic Study of Marine Atmospheric

Jul 03, 2015 · Marine atmosphere is one of the most corrosive environments to metallic structures due to its high content of airborne chlorides, mainly NaCl. 15 The high corrosion rates in marine environments greatly reduce the lifetime of steel structures. Therefore, a better understanding of the corrosion mechanisms of steel is necessary for evaluating the performance and developing corrosion Atmospheric corrosion data of weathering steels. A review Dec 01, 2013 · In 1910 Buck observed that steel sheets with 0.07% Cu manufactured by US Steel and exposed in three environments of different corrositivities (rural, industrial and marine) showed a 1.52% greater atmospheric corrosion resistance than CS . Hence, in 1911 US Steel started to market steel sheets with a certain copper content. Atmospheric corrosion of carbon steel at marine sites in Mar 18, 2010 · Atmospheric corrosion tests, according to ASTM G5076, have been carried out in Saudi Arabia, at eight marine sites representing different environmental conditions. Environmental factors such as average temperature, average relative humidity, and deposition rates of atmospheric pollutants (Cl and SO 2) was investigated. Xray

This article presents a synthesis of recent studies focused on the corrosion product layers forming on carbon steel in natural seawater and the link between the composition of these layers and the corrosion mechanisms. Additional new experimental results are also presented to enlighten some important points. First, the composition and stratification of the layers produced by uniform corrosion Carbon steel corrosion:a review of key surface properties carbon steel corrosion and its inhibition. This review therefore focuses on the importance of texture, surface morphology, surface energy and defects for the corro-sion of carbon steels. We discuss in detail the methods of analysis of carbon steel surfaces under corrosive conditions, and in the absence and presence of corrosion inhibitors. In Corrosion Behaviors of Carbon Steel and Ni-Advanced Oct 09, 2020 · The corrosion behaviors of carbon steel and Ni-advanced weathering steel exposed to tropical marine atmosphere were investigated by using electrochemical impedance spectroscopy, x-ray diffraction, transmission electron microscope and x-ray photoelectron spectroscopy measurements. The results showed that Ni had almost no effect on corrosion kinetics and electrochemical performance of

ENVIRONMENTAL FACTORS AFFECTING CORROSION OF

the effect of Cl _ ion on the atmospheric corrosion rate of carbon steel. In other to compare the marine effect with other atmospheric environment on the sample material, distances of 95 and 375 m from the sea line were considered for the carbon steel corrosion test after exposure to the atmosphere Evaluation of 4-Year Atmospheric Corrosion of Carbon Steel Atmospheric corrosion seriously affects the working life of construction metals. The quantitative knowledge of the corrosion effects helps the maintenance and the materials logistics. In this work, in a military airport located by the sea, the corrosion damage equations of carbon steel, aluminum, zinc and copper are determined after outdoor exposure for four years. In situ Raman Spectroscopic Study of NaCl Particle-Induced Jan 23, 2012 · The NaCl particle-induced atmospheric corrosion has been studied extensively for copper, 27 zinc, 811 iron, 12,13 aluminum, 14 and magnesium. 15 Less work 16 has been conducted on single NaCl particle-induced corrosion on steel, except for the studies on pre-deposited salt droplet-induced corrosion on carbon steel 17 and galvanized steel
