Abstract
The invention provides a preparation method of superhard composite material, and belongs to the field of material manufacture technology, and the method comprises the following steps: selecting a TiCu alloy whose Ti content is 30-75% from Fe, Ni, Co system, mixing the grinded TiCu alloy and Al powder, pressing into a plate shaped metal binder; placing a plate shaped metal binder into the bottom of a cylindrical heating block which is prepared from graphite material, injecting cubic boron nitride powder into the cylindrical heating block, placing the heating block into a high temperature high pressure apparatus, gradually pressurizing to 30 kPa, simultaneously heating, after naturally cooling, forming a cutlery material from the metal binder and the cubic boron nitride powder. When the cutter cuts a steel member whose quenching hardness is 40 HRC with linear velocity 90 meter/min, the usage life of the cutter produced by the method reaches to 90 minutes, and the yield reaches to 85-90%.
