“…The effect of screw was ignored. The chemical composition of specimen is shown in Table 1 Before each test run, the metal specimen was abraded with glass emery paper of grade numbers: 120, 180, 220, 400 and 2000 respectively, washed by tap water followed by distilled water, dried with a clean tissue followed by ethanol for 30 seconds, dried with clean tissue, and then dried by using electrical oven at a temperature of 110 ºC for 10 minutes [5,6,7].…”

Galvanic corrosion of Nickel-Chrome alloy (NiCr alloy) and Copper (Cu) coupled in 5% sulfuric acid solution was investigated. The effects of agitation velocity, temperature, and time on the galvanic corrosion current and the weight loss of both metals in both free corrosion and galvanic corrosion were investigated. The trends of open circuit potential (OCP) of each metal and galvanic potential (Eg) of the couple were also determined. The results showed that Cu was cathodic relative to Ni-Cr alloy in galvanic couple and the corrosion potential of the couple (Ni-Cr alloy /Cu) was between the values of the two single components because the OCP of copper shifted to positive with the increase in velocity. Under stagnant conditions initially the galvanic current was more negative then shifted to the positive with time. The corrosion of Ni-Cr alloy decreased with time because the passivation layer was formed on the surface. Under flow conditions, the galvanic current sharply shifted to the negative direction (increase galvanic current from Ni-Cr alloy (anode) to Cu (cathode) during the first few minutes.

“…It is evident that the aeration condition has a noticeable effect on the free corrosion potential and galvanic corrosion potential. The aeration leads to an increase in O 2 concentration shifting the potential to more positive [10], [12], [13]. This is a general trend, but in some occasions the potential with aeration is seen to be more negative than without aeration.…”

Corrosion rate tests were carried out on carbon steel under concentration cells conditions of oxygen and sodium chloride. The effect of aeration in one compartment on the corrosion rate of both coupled metals was determined. In addition, the effects of time and temperatures on the corrosion rate of both coupled metals and galvanic currents between them were investigated. Corrosion potentials for the whole range of operating conditions under concentration cell conditions were also studied. The results showed that under aeration condition, the formation of concentration cell caused a considerable corrosion rate of the Carbon steel specimens coupled in different concentrations of O2 and NaCl due to the galvanic effect. Aerating one compartment caused a noticeable increase in the corrosion rate of the coupled specimen in the other compartment due to the galvanic effect. Increasing temperature caused unstable trends in the free and galvanic corrosion potentials. Increasing the temperature led to an increase in the corrosion rate for both metals.

Corrosion is the degradation of the metal as a result of chemical reactions with its surroundings. However, corrosion can be predicted, in some cases significantly slowed down or prevented. In this study, the effect of galvanic corrosion formation on the tensile strength of AA7075-galvanized steel joints produced by cold metal transfer welding, which is one of the manufacturing methods used in forming many constructions, was investigated. The aluminum and steel pair are difficult to combine with other welding methods. Joining is provided by this method. Corrosion in this joining was investigated in this article. As a result, increased heat input during welding adversely affected galvanic corrosion and increased material dissolution.
