  • Method for applying protective coatings
    Patent number: 4684447
    Abstract: Flame sprayed aluminum coatings have been shown to be of excellent value in providing cathodic protection to steel structures in a marine environment. The common method of applying flame sprayed aluminum to a steel substrate comprises providing an anchor pattern to the substrate. Such anchor pattern can result in fatigue cracking of the substrate developing within the surface discontinuities of the anchor pattern. The present invention provides a method for providing a layered electroplated aluminum base coating on the substrate to which a flame sprayed aluminum coating may adhere without the need for a roughened surface on the substrate with its consequent potential for reduction of fatigue strength.
