Abstract: A method of preparing and decontaminating a substrate surface to remove contaminants including the steps of applying a first dry or fluid composition having a pH of 4 or less comprising an acidifier and an oxidizer, allowing the first composition to remain on the substrate surface for a predetermined period of time, and rinsing the first composition from the substrate surface with a second composition having a pH of 8 or more comprising an alkaline material liquid mixture formed utilizing activated carbon filtered potable water to achieve a neutral pH condition on the surface, and then applying a nanotubes coating on the surface.

Abstract: A method for passivating substrate surfaces by removing surface contaminants. The method can remove impurities and components from the surface of a substrate to prevent corrosion and undesirable chemical activity. The method further provides an optimized surface for the application of protective barrier coatings. The method provides significant cost savings due to increased life of substrate, reduced maintenance, and superior barrier coating performance.

Abstract: A powder treatment kit for decontaminating metal and metal containing surfaces, removing mill scale, improving the integrity of weldments, removing sulfides, greatly reducing surface oxidation, and mitigating the failure of protective coatings. The powder treatment kit for cleaning substrate surfaces for removal of water and non-water soluble oxides, ionic compounds, oxidized metal species, or other contaminants, comprising a surface pH modifier with a weight percent from 30 percent to 90 percent; a water-soluble oxidizer to react with non-water-soluble sulfides attached to the metal surface, to be dispersed, in an amount from 0.1 wt % to 50 wt %; a pH buffer to maintain a resulting solution pH from 1.5 weight percent to 69.8 weight percent; and a surface tension reducing component.

Abstract: A method is disclosed for preparing a substrate for coating. The method uses a step of applying an acidic solution to the substrate to break down visible and non-visible layers of surface material. The method also uses a step of applying a treatment solution to decontaminate the substrate. The method further comprises a step of applying an aqueous rinsing solution to the substrate to remove neutralized ionic contaminants for the substrate.

Abstract: A method is disclosed for removing water soluble salts from a metal substrate in a wet blast system in which a bicarbonate abrasive is blasted in a pressurized water stream against the surface of the metal substrate to prepare the surface for the application of a coating. The method includes the steps as indicated in FIG. 3 in which a high pressure wet blast pressurized water and sodium bicarbonate abrasive is first applied by a nozzle (14) against the surface of the metal substrate with the water soluble salts being removed or neutralized. Iron salts are present where the metal substrate is of a ferrous material such as iron or steel. Next, pressurized water without abrasive is applied by the nozzle (14) against the surface of the metal substrate for washing the surface clean and removing the neutralized water soluble salts. The water for the wet blast system is of a very high purity characterized by a conductivity of between 0.5 and ten (10) micromohs/cm.
