Two dissimilar metals
WebGalvanic corrosion occurs when two dissimilar metals make electrical contact in the presence of an electrolyte. [Figure 12] The rate which corrosion occurs depends on the difference in the activities. The greater the difference in activity, the faster corrosion occurs. The rate of galvanic corrosion also depends on the size of the parts in contact. WebFeb 10, 2011 · 2.3.11.4.3 Dissimilar Metal Welds.
