Abstract
The present invention provides a gradient material layer and a method for manufacturing the same. The gradient material layer has a base-material region, a diffusion region, and a compound region, wherein the diffusion region is located between the base-material region and the compound region. The base-material region includes a metal material. The diffusion region doped with nitrogen includes the metal material. The compound region includes metal nitride. The nitrogen content of the compound region is greater than that of the diffusion region.
