| Abstract: | This paper reported the bending strength improvement with relation to cobaltic phase structure of laser heat treatment in the surface of cemented carbide. The change of surface structure of YG20 cemented carbide was analyzed. The energy density with relation to bending strength are discussed. The microhardness, wear resistance, toughness of cemented carbide are improved. Some experimental results were given. |
| Keywords: | cemented carbide toughness laser treatment |
