Paper Title:
Microstructure of Laser Cladded Cobalt-Based Alloy Coating on T10 Tool Steel
  Abstract

Co-based alloy coating was fabricated by powder feeding laser cladding on T10 tool steel. The microstructure and phase composition were investigated by scanning electron microscope (SEM) and X-ray diffractometer (XRD). The results showed that the different solidification microstructures on the section, such as planar, cellular and dendrite formed from the interface to the surface. The main phase γ-Co and another phase Cr23C6 existed in the original coating, however, the main phase γ-Co was unchanged, and another phase was replaced by Cr7C3 accompanying with Co3C and Co4B precipitations after aging treatment.
