Graphitic corrosion of an impeller made of grey cast iron. Selective corrosion occurs in metals in which the alloying elements are not uniformly distributed. Typical examples of this type of corrosion are: Dezincification of brass, whereby zinc is dissolved and leave behind a porous copper material.
May 15, 2003· By definition, corrosion is the partial or complete wearing away, dissolving or softening of any metal substance by chemical action. The term ''rust'' is often misapplied or misused, as it applies only to iron and steel. The term ''corrosion,'' however, is all inclusive, in that it not only applies to ferrous metals but also to nonferrous metals.

Corrosion is usually defined as the degradation of metals due to an electrochemical process. The formation of rust on iron, tarnish on silver, and the bluegreen patina that develops on copper are all examples of corrosion. The total cost of corrosion in the United States is significant, with estimates in excess of half a trillion dollars a year.
Reinhart found that copper and its alloys of aluminum, silicon, tin, beryllium, and nickel had significantly lower longterm corrosion rates after 18 months compared to those specimens measured after only 6 months of exposure to seawater (Figure 3). 3 The only exception was Alloy C28000, Muntz metal, which exhibited a slightly higher corrosion rate after 18 months as compared to 6 months.
Brochure "Corrosion Inhibitors for Metalworking Fluids" Corrosion inhibitors marketed by Evonik under the trade name REWOCOROS® exhibit excellent corrosion inhibition properties for steel, iron, aluminum, and other metals. Typically REWOCOROS® products are offered as compounds based on fatty acid amides, alkanolamides, boric acid or imidazolines.
Copper corrosion is the corrosion of materials made of copper or copper alloys When exposed to the atmosphere, copper oxidizes, causing bright copper surfaces to tarnish After a few years, this tarnish gradually changes to dark brown or black, and finally to green.
