This article on corrosion inhibitors (or materials which reduce the corrosion rate by diminishing the tendency of the metal to react with the environment) includes many schematic chemical equations for general and specific corrosion processes. The discussion focuses upon the various classifications of inhibitors (anodic, cathodic, mixed, organix), volatile inhibitors, and situations in which corrosion inhibitors should be used (concrete which is to be reinforced by iron, show cases). See also 20-957 for complete book. -- AATA
