    摘要: 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 for preventing or retarding corrosion and methods for applying the buffered compositions to metal products such that corrosion protection of the products is achieved through passivation. 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 a carrier component and one or more pH buffer components. The buffer is selected to retain the proximity of the metal at a pH at which the metal is passive to corrosion. The compositions are environmentally friendly and are capable of replacing chromates which have been traditionally used with zinc and zinc alloys to inhibit corrosion of metals but which are potentially harmful to the environment.

    摘要: The disclosure relates to the forming of 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 useful 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.
