Use of cathodic coatings to cause selective, rapid decay of substrate metals

A self-destructive aquatic device for use in a water environment is formed with a body having a metallic portion and a covering preventing exposure of the metallic portion of the body from the water environment. A gap in the covering is used to expose the metallic portion of the body to the water environment. The covering has a cathodic property with respect to the metallic portion of the body, so that the gap and the covering establishing a cathodic-anodic ratio of areas exposed to the water environment to promote erosion of the metallic portion of the body in the water environment. This, in turn, results in controlled break-up of the aquatic device.
