Chapter 140 Corrosion prevention and control

摘要: Publisher Summary This chapter discusses corrosion prevention and control. As the community is becoming aware of costs corrosion, it also problems associated with many standard methods Corrosion, its control an enormous section science metals; served by disciplines including metallurgy, electrochemistry, physics, chemical engineering. Metallic in aqueous environments electrochemical process generally consisting two or more partial reactions, which occur at near microstructural features on metal alloy surface. These include grain boundaries, intermetallic phases particles flaws naturally occurring protective oxide films. A simple schematic shown chapter. In addition, rates metals alloys may be measured a number techniques. The simplest procedure for determining rate to measure weight coupon before after exposure given environment, calculate loss weight, divide time surface area.
