  • Patent number: 8287663
    Abstract: A process for forming a magnetite coating on a ferrous metal surface and for chemical reagents used to implement the coating process. The process comprises the step of making the ferrous metal surface more reactive by contacting the surface with an activating reagent and then contacting the activated surface with an oxidizing reagent to form the coating at a relatively low temperature range. The surface is activated by contact with an acid solution to form a surface rich in reactive iron. The activated surface is then oxidized by contact with an aqueous reagent of alkali metal hydroxide, alkali metal nitrate, alkali metal nitrite, and mixtures thereof.

    Abstract: A surface treatment method of a magnesium alloy article includes, instead of forming a primer on a magnesium alloy based composite first, directly performing a hairline finish process on the magnesium alloy based composite, to form a hairline structure on a surface of the magnesium alloy based composite, and performing a chemical oxidation process on the magnesium alloy based composite, to form a glossy film covering the hairline structure on the magnesium alloy based composite, thereby forming a magnesium alloy article structure. Alternatively, another chemical oxidation process is performed before the hairline finish process, to form an oxide film on the surface of the magnesium alloy based composite.
