“…The galvanic corrosion rate and the potential distribution over a galvanic couple are, in general, dependent upon the electrochemical properties of the metals, on environmental variables such as temperature, salinity, oxygen content, and solution flow, as well as the geometry of the corroding system. If dissimilar materials can be coupled without significant damage, a greater flexibility in the material selection may be possible (Varela et al, 1997;Zhang, 2011;Elsner et al, 2014).…”

“…Most of the previous studies have also reported agreement between modeling predictions and experimental measurements for the galvanic current distribution. [45][46][47][48][49][50][51][52] In contrast, Ault and Meany [53] concluded: a) "the deepest pit was not immediately adjacent to the cathodic metals that most mathematical models predict"; b) "the mathematical model only can provide a order of magnitude estimation of galvanic current flow"; and c) "the mathematical model can neither accurately predict long term current distribution nor the magnitude of pitting corrosion". These conclusions are of particular significance for the present study on the galvanic corrosion of magnesium because localized corrosion is often the form of corrosion of magnesium in practical solutions as typified by 5 % NaCl solution.…”

The study of the galvanic corrosion of magnesium becomes increasingly important as the use of magnesium alloys increases rapidly in the auto and aerospace industries due to their advantages of light-weight, adequate mechanical properties and moderate cost. Corrosion, however, limits the application of magnesium alloys. [1][2][3][4][5][6][7] A number of different mechanisms are important for the corrosion. [8][9][10][11][12][13][14] But galvanic corrosion is probably the most important for magnesium because magnesium is the most active structural metal and consequently may suffer serious corrosion when joined to all other common metals of construction, such as aluminum or steel. [1,2,15] Fasteners and their galvanic corrosion is of major concern in automotive applications. [16][17][18] Skar [17] showed that 6000 series aluminum alloy fasteners caused negligible galvanic corrosion of magnesium in the salt spray test. However, steel fasteners are desired for many applications due to their inherently better mechanical properties. Poor compatibility with magnesium was shown by aluminium-coated steel fasteners [18] whereas steel fasteners with zinc or tin-zinc alloy coatings were compatible with magnesium in salt-water exposure. [16] To be able to design a structural component, incorporating galvanic corrosion, it is useful to be able to simulate the galvanic corrosion distribution qualitatively. The research presented in this paper has been undertaken as part of a program to explore that aim. The total corrosion in the area of galvanic corrosion can be considered to be made up of the following two components: (1) galvanic corrosion and (2) self corrosion. The galvanic corrosion is that part of the corrosion, which is directly caused by the coupling of the magnesium to a steel fastener. The self-corrosion is defined as the extra corrosion. Both the galvanic corrosion and the self-corrosion may take the form of more or less general corrosion, or the form of localized corrosion or pitting corrosion.Prior studies of galvanic corrosion of magnesium have been scarce. The earliest study, started in the 1950s by Teeple, [19] investigated the influence of location and climate. This study revealed that different locations produced different corrosion rates because of the different electrolyte properties of the condensed film on the metal surface. [19] Atmospheric galvanic corrosion could be detrimental for magnesium in one location whilst it was almost harmless in another location. This provided helpful information to select magnesium for a particular location. However, the study was time consuming. It is often not practical to wait years to have the test results for each particular service location. Limited studies have addressed the effect of electrolyte on the galvanic corrosion of magnesium. More effort has been focused on general corrosion, particularly on the influence of the ion species in solution, and the influence of cathodic impurity elements in the alloy. [20][21][22][23][24][25][26][27][28] The influence of the ele...

“…Traditional materials supporting system are also constantly updated, so inevitably two or more metal occur electrical connection easy to form galvanic corrosion, that engineering design personnel adopted protective measures, such as coating, cathodic protection and insulation resistance and so on according to the existing research achievement [3,4]. But materials damage caused by galvanic corrosion still frequently happen in ocean engineering, After analyzing the causes, in addition to protective measures still needing to improve, corrosion behaviors rule and corrosion mechanism, influence factors all aspects should further study in the galvanic corrosion system [5][6][7].…”

Abstract. The galvanic corrosion behavior of Cu-Ni Alloy(B10)/high strength steel (921A) has been studied using a zero-resistance ammeter (ZRA) in seawater at different temperatures. As well as it was systemically investigated by weight loss measurements, electrochemical methods and scanning electron microscope.Results showed 921A acts as the anode and B10 act as the cathodes. The effect of temperature on the galvanic corrosion is important, the corrosion rate became higher with the temperature increased.
