Improved Coating System for High Strength Torsion Bars

Abstract

Eight candidate coatings were selected during Phase I and tested in comparison to the current tape and primer system used on the body section of suspension torsion bars. Laboratory tests involving coated panels and one-third length torsion bars were employed in determining the most cost-effective candidate. Production M113A2 torsion bars were coated with the selected product during Phase II and life tested in comparison to the current system. Each group of bars was subjected to a standard damage/corrosion method prior to endurance testing. A statistical analysis of bar life data quantified the increased protection level afforded by the Improved Coating System.
