Abstract
Automotive and associated industries investigated cyclic test methods for automotive finishes on steel. The goal was to develop a method which adequately relates to research, development and quality control needs for automotive steel finishes. This paper compares corrosion products and morphologies of attack on materials exposed to on-vehicle tests (Montreal, Quebec and St. Johns, Newfoundland) to the same materials exposed to selected laboratory tests. A variety of analytical tools was applied to compare laboratory and field tests with respect to corrosion mechanisms. A reasonable correlation was established between accelerated test H (PC-4) and field exposed specimens.
