摘要: |
The U.S. Army Corps of Engineers uses many hydraulic pistons on its Civil Works structures. Recent failures of ceramic coated piston rods in the Jacksonville District indicate that specifications for these rods need to be updated and enhanced. This report discusses results of tests performed on carbon steel rods with varying bond coats applied with one of several methods. Top coats were also varied, and sealers were used only on some of the specimens. Testing was to determine hardness and corrosion/impact resistance. Conclusions drawn in this study will be used to recommend modifications to Corps of Engineers Guide Specification 15010. |
