Abstract
Abstract Metal to rubber adhesion is improved by metal substrates having a coating thereon such as brass, copper, and the like. The coating is applied by an ion beam sputter deposition or, in the alternative, such a coating is partially removed through ion beam etching. The present invention is particularly useful in tire cord construction, metal reinforced belts and hoses, and the like, since articles made therefrom have superior and unexpected moisture aged rubber-to-metal adhesion properties.
