Carbide cutting tools in the hardware appliance its role is quite large, can be divided into many Categories!
Carbide cutting tools in poor fracture toughness of a prop, in the process, often have problems because of these reasons, it is difficult and in need of some toughness occasion only he, Suzhou Shuo Shuo Precision Tool to face this problem came up some solutions, is added thereto whiskers.

Carbide Tool whiskers can crack propagation energy-absorbing alloy, the size of the energy absorbed by the state whisker and matrix binding decision. When whiskers pulled out of the matrix alloy under external load is applied, because the interfacial friction consumed part load energy outside world, so as to achieve the purpose of toughening toughening effect by the whiskers and the impact resistance of the sliding interface. There must be a lot of bonding between the whiskers and the matrix interface, so that the external load can be effectively transmitted to the whiskers, and the binding force can not too much, in order to permit a sufficient length of pull. Crack deflection toughening: When the crack tip encounters elastic modulus of the matrix in the second phase, the crack will deviate from the original direction of advance along the two-phase interface or expand within the matrix. Due to the non-planar fracture crack than the fracture plane it has a larger fracture surface, so you can absorb more external energy, so as to achieve increased toughness.

Carbide Tool added a high elastic modulus of whiskers or particles can cause crack deflection toughening mechanisms within the matrix, when the matrix fracture, whiskers and can withstand external load disconnect between the crack faces play bridge connection effect. Bridging whiskers can make produce stromal crack closure force loads acting outside consumption, thereby improving toughness.
