    摘要： Provide a metal surface reforming method enabling metallic products with superior characteristics such as surface hardness, heat resistance, corrosion resistance, high temperature oxidation, high temperature corrosion, and environmental corrosion and the like.Halogenation treatment of heating and retaining a base material in an atmosphere containing a halogen based gas is performed on a base material of iron based metal or nickel based metal, then nitride processing of heating and retaining the halogenated base material described above in an atmosphere containing a nitrogen source gas is performed, then chromizing treatment is performed by placing the nitrided base material in a powder containing metal chromium powder to form a surface reformed layer on the base material described above. These metallic products obtained have high hardness, superior heat resistance and corrosion resistance, and exhibit superior performance in high temperature oxidation, high temperature corrosion, erosion, and cavitation and the like environments. Further, the metallic products described above exhibit superior performance in acid or alkali environments, neutral environments, and corrosive environments such as chlorides like salt water.

    摘要： A slurry and a coating method are provided. The slurry includes, by weight, between 10% and 40% metal powder, between 10% and 15% activator, between 10% and 20% adhesive, between 10% and 20% thickener, up to 30% ceramic, and up to 25% binder. The coating method includes providing a slurry including, by weight, between 10% and 40% metal powder, between 10% and 15% activator, between 10% and 20% adhesive, between 10% and 20% thickener, up to 30% ceramic, and up to 25% organic polymer binder, providing a substrate, applying the slurry over a surface of the substrate to form a slurry coating, drying the slurry coating over the substrate, baking the substrate and the slurry coating, and curing the slurry coating over the substrate. The curing the slurry coating over the substrate transfers metal elements of the metal powder in the slurry to the substrate to form a coating on the substrate.
