Corrosion Control in the Aerospace Industry

Corrosion control in the aerospace industry is an issue that has always been important, but is becoming more so with the ageing of the aircraft fleet. Corrosion can lead to non-availability of aircraft and in extreme cases catastrophic failure. As aircraft age, they are subjected to corrosive environments over longer periods, far beyond initial design considerations. The first part of this important book reviews ageing aircraft and the cost of corrosion. A second group of chapters discusses corrosion fundamentals and part three examines corrosion monitoring, evaluation and prediction. A final section analyzes methods of corrosion protection and prevention.
