SURFACE ALLOYED METALS AND METHODS FOR ALLOYING SURFACES

摘要

The disclosure provides a material that includes a stainless steel layer with a consistent composition diffusion bonded to a carbon steel substrate. The material can have the corrosion resistance associated with the explosively welded stainless steel and the deep diffusion bonding observed typical of chromizing applications.

1. A material that comprises an alloyed metal layer having an alloying agent, the alloyed metal layer being coupled to a substrate with the aid of a diffusion layer between the alloyed metal layer and the substrate, wherein the amount of alloying agent in the diffusion layer changes with depth at a rate between about −0.01% per micrometer and −5.0% per micrometer as measured by x-ray photoelectron spectroscopy.
