A method to improve corrosion, abrasion, resistance to environmental degradationand fire resistant properties of structural components for use in oil, gas, exploration, refining and petrochemical applications is provided. The structural component is suitable for use as refinery and/or petrochemical process equipment and piping, having a substrate coated with a surface-treated amorphous metal layer. The surface of the structural component is surface treated with an energy source to cause a diffusion of at least a portion of the amorphous metal layer and at least a portion of the substrate, forming a diffusion layer disposed on a substrate. The diffusion layer has a negative hardness profile with the hardness increasing from the diffusion surface in contact with the substrate to the surface away from the substrate.
