Abstract

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.
