Abstract: The objective of the tests described in this paper is to compare the effectiveness of
various substrates, coatings, and designs that are being used in the commercial
sector and that have demonstrated a high degree of usage and success. Corrosion
was observed on actual vehicle body components with CARC paints, E-coating
primers, pre-painted or coil coated steel, galvanized steel, structural adhesive and
the elimination or reduction of weldments. The marine exposure environment
was believed to be similar to Hawaii, Puerto Rico and Panama–aggressive
environments, which promote high corrosion rates. A secondary objective was to
establish a correlation between the testing at Cape Canaveral and the “rust belt” in
the continental US, Camp Jejune NC, and the GM9540 Cyclic corrosion test.
This paper describes testing of M151 jeep bodies, and production five-ton truck
doors. The long history and service life of these vehicles allowed them to serve as
ideal candidates for accelerated testing.
Pros/Cons: The study has resulted in a wealth of data that can be used to compare the
corrosion performance of various materials in various environments. The use of
this marine exposure testing coupled with on-going accelerated corrosion testing
will generate data to improve design, production, maintenance, and result in
reduced lifecycle costs of fielded material.
