Corrosion Control in Civil Works:Cathodic Protection.

摘要

This report presents the initial results of a study being conducted to mitigate corrosion in Corps of Engineers civil works structures. This phase of the study dealt with specific aspects of cathodic protection. Basic electrochemical principles and cathodic protection experiments particularly germane to civil works problems are discussed,and an innovative investigation of cathodic protection current distribution using the continuum features of electric field analysis is presented. Recently developed automatic controlled rectifiers are analyzed,and their control response measured for applications involving brackish water. Guidelines for application of cathodic protection principles to system design are also presented. (Author)
