Abstract
The present invention relates to a coated article. The coated article includes a first layer, a second layer, and a diffusion region between the first layer and the second layer. The first layer has a first atomic concentration of C, a first atomic concentration of Si, and a first atomic concentration of O. The second layer has a first atomic concentration of Fe, a first atomic concentration of Cr, and a first atomic concentration of Ni. The diffusion region has a second atomic concentration of the C, a second atomic concentration of the Si, a second atomic concentration of the O, a second atomic concentration of the Fe, a second atomic concentration of the Cr, and a second atomic concentration of the Ni. All of the atomic concentrations are based upon Auger Electron Spectroscopy.
