The oxide layers formed by copper and its alloys are porous and "leaky," allowing water, oxygen, and copper ions to move to and from the metal surface (Figure 19-2). The rate of movement is controlled by the copper oxide film thickness. As the oxide layer grows in thickness, the copper oxidation rate is slowed. sicily coloring pages
