Now that we are familiar with the structures of single chain macromolecules, we are in a position to look at some of the interactions of macromolecules with other macromolecules and with smaller molecules.
Corrosion on exposed metal. Corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.
Metals that are dissimilar to one another, vary with regard to their differences in corrosion. Galvanic corrosion is a process that indicates a comparison of how metals corrode differently when in contact with an electrical connection.This system of ranking dissimilar metals is called the Galvanic Series which gives a good suggestion of which metals will be more likely to corrode first.alvanic Corrosion. According to the Multimedia Corrosion Guide, the definition of Galvanic Corrosion is âthe effect resulting from contact between two different metals or alloys in a conducting corrosive environmentâ.
