The Response of Coated Steels to Cavitation in Corrosive Environments.

Abstract

Cavitation-erosion in marine environments can have serious, deleterious effects on coated steels. This work is aimed at a detailed understanding of these effects. Studies are being carried out on aluminum-zinc alloy and alumina-base ceramic coatings. The resistance to corrosive media of these coated steels are being studied, with and without polyurethane impregnation of the porous coating, since polymer-filled flame sprayed anodic coatings are known to give remarkable corrosion protection in a range of marine environments. Details of the thermal spray process are also being examined as these effect properties. Furthermore, transition metal/metalloid amorphous coatings are being examined. It is our intent to study erosive/corrosive effects where, for modern, high velocity marine vehicles, they are certain to play an important role. (Author)
