Corrosion Failures: Identification, Diagnosis & Remedies

Abstract

This paper deals with the nature, typical surface features and common forms of corrosion. It also reports corrosion rates in various locations and under differing environmental conditions, viz. tropical, marine, urban and industrial. Rates of corrosion failures may well overweigh those of mechanical failures. Measures taken to control corrosion, mainly include proper selection of materials, application of suitable protective coatings, alteration of environment and careful design of components and assemblies. These remedies no doubt exert differing influences on part life and economy. Correct diagnosis of failures would evidently help in making the right decision as to the most effective protective measures to be taken
