  • Patent number: 6399021
    Abstract: A system is disclosed for inhibiting the corrosion of ferrous and other metals by passivating the metals. The system includes novel buffered compositions which may be applied to metal products, and novel combinations thereof with metals, for preventing or retarding corrosion, as well as methods for applying the buffered compositions to metal products, such that corrosion protection of the products is achieved. The methods include an in-situ application to existing structures with metal reinforcement as well as applications to metal products during manufacture. Generally, the compositions may be in various forms and comprise one or more layers, at least one of which includes a water repellent but water vapor permeable carrier component and one or more pH buffer components. The buffer is selected to produce a passivating pH at the surface of the metal.

  • Patent number: 6309478
    Abstract: The disclosure relates to aqueous-based gels and, in some cases, usage of such gels to impart corrosion resistance to steel and/or zinc containing surfaces, e.g., galvanized steel. The gel comprises water, at least one thickener, at least one silica containing material and an optional surfactant.

  • Publication number: 20010024729
    Abstract: The disclosure relates to the forming mineralized coatings on metal surfaces and to methods of forming such coatings. The coating can include a wide range of compounds and normally at least a portion of the coating corresponds to an amorphous phase. The coating and method are particularly usefull in providing a corrosion resistant coating or film upon a metallic surface. This aspect of the disclosure involves the formation of a corrosion resistant “mineralized” layer of tailored composition upon a metal substrate.
