  • Method of applying polyelectrolyte multilayer film for corrosion control
    Patent number: 8613847
    Abstract: The method of applying a polyelectrolyte multilayer film for corrosion control involves chemical and/or electrochemical pretreatment of a metallic substrate for better adherence of the protective film to the substrate. The method includes anodically polarizing the substrate in a solution of an acid for a period from one second to five hundred seconds before multilayer deposition. The acid may be an inorganic acid, such as sulfuric acid, phosphoric acid, hydrochloric acid, nitric acid, etc., or an organic acid, such as oxalic acid, acetic acid, etc. The method may include abrading the substrate and rinsing the substrate with deionized water before polarizing the substrate, and applying the polyelectrolyte multilayers following pretreatment.
