What characterizes uniform corrosion?

Explanation:
Uniform corrosion happens when the metal loses material at about the same rate across the entire exposed surface. This even distribution of electrochemical activity causes the surface to thin uniformly, rather than developing localized features. In contrast, pits form as deep holes in small areas, intergranular attack travels along grain boundaries, and pitting is another form of localized corrosion. So the defining characteristic is the even, uniform thinning of the exposed surface.
