[0026] Example 1:
[0027] A method for laser roughening of diamond, which includes the following steps in sequence:
[0028] (A) Prepare and clean diamond particles;
[0029] (B) Use laser ablation to hit the surface of the diamond particles in step (A);
[0030] (C) Adjust the position of the laser on the surface of the diamond particles. The laser ablates several small pits on the surface of the diamond particles to roughen the surface of the diamond particles.
[0031] In this embodiment, after the diamond particles are cleaned to remove impurities, a laser is used to ablate the pits on the surface of the diamond particles to roughen the surface of the diamond, thereby improving the mechanical engagement strength between the diamond particles and the binder, and at the same time the roughened Many small cutting edges are formed on the surface of diamond particles, which improves the cutting and grinding precision of diamond particles. Using the above method to roughen the diamond ...
Example Embodiment
[0032] Example 2:
[0033] A method for laser roughening of diamond, which includes the following steps in sequence:
[0034] (A) Prepare and clean diamond particles;
[0035] (B) Use laser ablation to hit the surface of the diamond particles in step (A);
[0036] (C) Adjust the position of the laser on the surface of the diamond particles. The laser ablates several small pits on the surface of the diamond particles to roughen the surface of the diamond particles.
[0037] In step (A), the diamond particles are artificial single crystal diamonds. In this embodiment, the diamond particles are artificial single crystal diamonds, and artificial single crystal diamonds are used as the raw material. The cost is low and the raw materials are sufficient, which can meet the needs of industrial production for large quantities of raw materials. Demand.
[0038] The other parts of this embodiment are the same as the embodiment 1, and will not be repeated here.
Example Embodiment
[0039] Example 3:
[0040] A method for laser roughening of diamond, which includes the following steps in sequence:
[0041] (A) Prepare and clean diamond particles;
[0042] (B) Use laser ablation to hit the surface of the diamond particles in step (A);
[0043] (C) Adjust the position of the laser on the surface of the diamond particles. The laser ablates several small pits on the surface of the diamond particles to roughen the surface of the diamond particles.
[0044] The diameter of the diamond particles in step (A) is 1 to 1000 microns, and the diameter of the laser beam in step (B) is 0.1 to 0.2 of the diameter of the diamond particles. In this embodiment, the diameter of the diamond particles is 1 to 1000 microns, and the diameter of the laser beam is 0.1 to 0.2 of the diameter of the diamond particles. The diameter of the laser beam is adjusted according to the diameter of the diamond, and the laser burning is flexibly adjusted. The size of the pit caused by the erosion.
