Because of the signi? cant economic, safety, and historical impact of corrosion on society and because corrosion of metals is an electrochemical process, it is also not surprising that the Corrosion Division is one of the oldest divisions within ECS. The Division was established in 1942, but corrosion has the design procedure for a sacrificial cathodic protection system. The problem of partial cathodic protection of a pipe line by concen-trating on "hot spots" is discussed in Chapter 8. A problem in Chapter 9, which does not usually occur nowadays, is that of stray-current cor-rosion; however, a corrosion engineer should still be able to This volume is devoted to the corrosion performance of materials and the selection and application of materials for corrosion resistance. The 700-page ASM Handbook covers ferrous and nonferrous metals; processed materials, including thermal spray coatings, electroplated materials, and clad metals; and special products. overlay, and membranes. Corrosion of steel and corrosion-induced damage in concrete occurred in all bridges except the Dry Creek Bridge, which is relatively new. The degree of corrosion is quite high. Nine other bridges with different corrosion protection systems were inspected to study the effectiveness of these protection methods. Corrosion inhibitors are substances that are added in small amount (e.g 0.1%) to the corrosive medium stop or slow down electrochemical corrosion reactions on a metal surface. Mechanism: Corrosion inhibitors work by one or more of the following mechanisms. Answer: Stress corrosion not uniform because a mechanically stressed structure is highly strained at certain locations, which become the localized anodic sites for corrosion to take place there. 1.9 What form of corrosion develops at rivets and bolts? Answer: Crevice corrosion 1.10 Corrosion is a process of destruction of a metal surface by the TECHNICAL MANUAL CLEANING AND CORROSION CONTROL VOLUME I CORROSION PROGRAM AND CORROSION THEORY 01 MARCH 2005 This publication supersedes NAVAIR 01-1A-509/TM 1-1500-344-23, dated 1 May 2001 and NAVAIR 16-1-540/TM 1-1500-343-23/TO 1-1-689, dated 1 Sep 2000.
