文摘The carburized graded cemented carbide with the addition of some（Ti,Ta） C was analyzed in detail.The micro-structure and element distribution were measured by using optical microscopy and X-ray photoelectron spectrometry along the gradient direction.The experimental results showed that a large amount of solid solution phases were formed and distributed like clusters in the surface layer of cemented carbide.The cobalt migration was not very notable and the Co-rich layer was close to the surface of cemented carbide.
