If the Ionic or Electro-chemical theory of corrosion, as described in the preceding chapter, be accepted it is then easy to divide all practical cases of corrosion into three types : (1) Auto Corrosion, (2) Contact Corrosion, and (3) Externally Induced Corrosion. (reference).
The solution is to prevent such direct contact with the use of separating materials, such as specific paints or gaskets. It is not necessary to isolate copper from lead, tin or stainless steel under most circumstances. The principal metals of concern in terms of direct contact are aluminum and zinc.nother type of corrosion, which affects copper, is caused by the flow of acidic water concentrated on a small area of copper. This type, often called erosion corrosion, occurs when rain falls on a non-copper roof such as tile, slate, wood, or asphalt.
