A coating having a gradient composite structure, applied to a substrate, which may be a disposable tool. The gradient composite comprises a bonding component and an erosion and/or corrosion resistant component. When applied to a disposable tool, such as a ball and seat assembly in a downhole environment, the coating enhances the performance of disintegrable materials used in such tools. The coating may be configured to expire at the end of a selected duration, allowing the underlying material to disintegrate.

The present invention relates to a surface-treated steel plate and to a production method for same, and more specifically relates to a surface-treated steel plate having outstanding corrosion resistance and thermal conductivity. In order to achieve this aim, in the present invention a macromolecular resin composition comprising graphene, which has highly outstanding physical properties including electrical conductivity, is coated onto the surface of a steel foundation plate, thereby making it possible to provide a surface-treated steel plate able to supremely well ensure not only corrosion resistance but also the intrinsic characteristics of graphene due to the macromolecular resin composition.
