Surface Protection Study for Navy Projectiles,
Abstract
This report documents the testing and evaluation of various organic and inorganic surface coatings exposed to marine environments. Results from a comparative series of qualitative performance tests are presented with emphasis on paint primers, and primers plus topcoat. Both laboratory and field testing of an accelerated nature were done on steel substrates with the selected coatings. Test specimens included both coupons and end items that consisted of Navy, gun-fired projectiles. The coatings examined included three types of powder coatings (epoxy, polyester, and nylon), an electrodeposited epoxy, a metallic-ceramic, an aluminized-phenolic, an inorganic zinc, a two-part epoxy, a silicon-oxide, and an alxyd paint system as control. The main purpose was to identify surface coatings with improved corrosion resistance, abrasion resistance, and better compliance to environmental standards, than the present paint system used on Navy ammunition components. The use of trade names and manufacturers' names in this report constitutes neither endorsement nor disapproval of any commercial entity.
