Evaluation of Coatings for Air/Fluid Accumulators.

Abstract

This report describes a sequential two-phase evaluation of the corrosion and wear resistance of ten coatings on AISI 4130 steel under conditions simulating those present in catapult accumulators and arresting gear accumulators used on aircraft carriers. In Phase I, ten coatings were subjected to wear tests and short-term corrosion tests. Five of the coatings were selected for additional evaluation in Phase II which included continued corrosion tests, wear tests and mechanical properties tests. The best overall performance was exhibited by Tribaloy 800 which appears to be the most promising coating for protection of both catapult and arresting gear accumulators. Other coatings which appeared satisfactory were, in order of decreasing effectiveness, Nedox and Selectron Ni-Co for use in the catapult accumulator and Selectron Ni-W and Nedox in the arresting gear accumulator. A Nylon 11 coating was unsatisfactory because of coating blistering in corrosion tests in both hydrualic fluids and in the simulated arresting gear wear tests. (Author)
