Abstract

This article discusses the commonly encountered forms of automotive body corrosion. The corrosion forms include general or uniform corrosion, cosmetic or under-film corrosion, galvanic corrosion, crevice corrosion, poultice or under-deposit corrosion, and pitting corrosion. Corrosion-resistant sheet metals, such as electrogalvanized steel, hot dip galvanized steel, and hot dip galvannealed steel, are reviewed. The article provides information on the paint and sealant systems for corrosion control in automotive body applications.

Abstract

Steel automotive exhaust systems suffer from various forms of corrosion. This article illustrates exhaust system components with typical upper metal skin temperatures and alloys of construction. It discusses high-temperature corrosion of automotive exhaust systems, including oxidation, hot salt attack, and thermal fatigue. The article describes the various forms of corrosion which occur at the cold end of an exhaust system. The forms of cold end exhaust corrosion, including condensate pitting corrosion, exterior salt pitting, crevice corrosion, intergranular corrosion, and galvanic corrosion.
