INVESTIGATION OF SONAR DIAPHRAGM COATINGS

Abstract

INVESTIGATIONS WERE MADE OF COMMERCIAL COATING MATERIALS FOR SONAR EQUIPMENT, PARTICULARLY SONAR DIAPHRAGMS CONSTRUCTED OF 5% Cr steel, Vasco-Jet 1000. Properties sought included elasticity to withstand vibration of the sonar diaphragm, resistance to the natural environment (sea water and salt atmosphere) , air drying, and adhesiveness. Of the 19 coatings tested, a polyurethane product, Laminar X-500, passed the tests and possessed the required qualities. When properly applied this material is exceptionally effective in the protection of underwater equipment.
