  • Galvanic and Corrosion Compatibility Dissimilar Metal

    Galvanic corrosion (some times called dissimilar metal corrosion) is the process by which the materials in contact with each other oxidizes or corrodes. There are three conditions that must exist for galvanic corrosion to occur. First there must be two electrochemically dissimilar metals present. Second, there must be an electrically conductive path between the two metals. And third, there

    21/8/20200183;32;In its pure form, iron is a silvery white metal, distinguished by its ability to take and retain a magnetic field, and also dissolve small amounts of carbon when molten (thus yielding steel). Commercial refining of iron is based on the heating of \(Fe 2O 3\) or \(Fe 3O 4\) (magnetite) with a mixture of other substances in the high temperature environment of the blast furnace.
