20090252986 | Anti-corrosive coating for metal surfaces - A protective coating for a metal substrate is provided that is light, durable, galvanically protective, and easily applied at the site of manufacture. The coating has at least two layers, one of which is a galvanizing layer and one of which is a micro-composite of a galvanic metal and a non-conducting material, such as polymer. Such coatings are useful for example to protect pipes or other metal surfaces in corrosive environments. Methods of producing the coating are provided, including methods that use advanced spraying techniques to provide very thin but consistent layers. Using the advanced spraying methods the composite layer can be created by co-spraying the galvanic metal and the nonconductive material onto the surface of the galvanic coating. Optionally, an outer coat of insulating material can be applied to provide further protection to the surface. | 10-08-2009 |
