Cemented carbide and cutting tools |
| abstract |
A cemented carbide having a first hard phase comprising tungsten carbide particles and a bonding phase comprising Co and Cr, adjacent to each other with a face length L of 100 nm or more on any surface or any cross section of the cemented carbide The region where the distance (X) between the surfaces of the tungsten carbide particles is 5 nm or less is defined as a WC/WC interface, and the distance (X) is 1 nm or more and 5 nm or less and is also at the WC/WC interface. At the WC/WC interface where the atomic concentration of Co is higher than the average value of +2 at% of the atomic concentration of Co in the tungsten carbide particles, the atomic concentration C(C) of Co and the atomic concentration C(R) of Cr Cemented carbides with a ratio C(R)/C(C) of 0.17 or more. |
