This study is concerned with the general problem of cavitation erosion; in particular, with coatings which can provide protection of marine and other structures against cavitation erosion and which can remain adhered when exposed to severe hydrodynamic environments. Cavitation erosion studies were conducted on 25 coatings, comprising both neoprene and polyurethane formulations; the Naval Applied Science Laboratory (NASL) magnetostriction apparatus was used as the principal test device. The most erosion resistant of the coatings tested were found to be polyurethane formulations. Adhesion tests on the more erosion resistant coatings showed no effect of cavitation exposure on strength of adhesion. Comparison of magnetostriction data with data obtained on the NASL rotating disk apparatus showed that cavitation intensity of the magnetostriction test (under presently maintained operational parameters) exceeded the most severe intensity developed by the rotating disk apparatus.
