Long-Term Wear and Immersion Tests of Polymeric Coatings
Abstract
This report describes an evaluation of four polymeric coatings, applied over AISI 4130 steel, subjected to conditions simulating those occurring in catapult accumulators used on Navy aircraft carriers. Both wear and immersion specimens were exposed to MIL-H-22072 Hydraulic Fluid which was heated to 160 F eight hours per day, five days per week for six months. Duplicate tests of each type were run. The wear (ring) specimens were also subjected to reciprocating sliding motion against bronze block specimens under an eight-lb load. Evaluation criteria included coating wear life expressed as hours of sliding or sliding distance and corrosion resistance based on microscopic examinations of the immersion specimens.
