[0028] The preparation method of the pre-alloyed powder used in the composite binder abrasive tool for grinding hard and brittle materials of the present invention comprises the following steps: 1) Bronze powder, Sn powder, multi-element pre-alloyed powder, Ti powder and MoS 2 Mixing and ball milling for 3-20 hours to obtain mixed powder; 2) performing heat treatment on the mixed powder, and then cooling to obtain the final product; the heat treatment is to keep warm at a temperature of 300-600° C. for 0.5-8 hours.
[0029] The multi-component pre-alloyed powder in step (1) is composed of at least one of Co, Ni, Cu, Sn, Zn and Fe. The volume percentage of Fe is 50-99%.
[0030] The average particle diameter of the Ti powder and the average particle diameter of the multi-element pre-alloyed powder in the step (1) are both 0.5-3 mm.
[0031] Preferably, the mass ratio of ball to material during ball milling is (1-8):1. Further preferably, the mass ratio of ball to material dur...
Embodiment 1
[0036] The pre-alloyed powder of the present embodiment is made of the following raw materials in parts by volume: 42.2 parts of bronze powder, 20 parts of Sn powder, 18 parts of multi-component pre-alloyed powder, 16 parts of Ti powder, 3.8 parts MoS 2 pink.
[0037]Wherein the mass percentage of Cu in the bronze powder is 90%, the mass percentage of Sn is 10%; The particle content is 20%, the particle size of the multi-component pre-alloyed powder is 0.5 μm; the particle size of the Ti powder is 3 μm; the particle size of the MoS 2 The particle size of the powder is 9 μm, which is 3 times of the particle size of the Ti powder, and its volume fraction is 11.2% of the sum of the volume fraction of the multi-component pre-alloyed powder and the Ti powder.
Embodiment 2
