Embodiment 1

[0027] A method for roughening diamond by laser, the method for roughening diamond by laser comprises the following steps in sequence:

[0028] (A) preparing diamond particles and cleaning;

[0029] (B) Laser ablation is used to strike the laser on the surface of the diamond particles in step (A);

[0030] (C) Adjust the position of the laser on the surface of the diamond particles, and the laser ablates several small pits on the surface of the diamond particles, so as to roughen the surface of the diamond particles.

[0031] In this embodiment, after the diamond particles are cleaned to remove impurities, the laser is used to ablate pits on the surface of the diamond particles to roughen the diamond surface, thereby improving the mechanical engagement strength between the diamond particles and the bonding agent, 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 diam...

Embodiment 2

[0033] A method for roughening diamond by laser, the method for roughening diamond by laser comprises the following steps in sequence:

[0034] (A) preparing diamond particles and cleaning;

[0035] (B) Laser ablation is used to strike the laser on the surface of the diamond particles in step (A);

[0036] (C) Adjust the position of the laser on the surface of the diamond particles, and the laser ablates several small pits on the surface of the diamond particles, so as 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 raw materials. 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.

Embodiment 3

[0040] A method for roughening diamond by laser, the method for roughening diamond by laser comprises the following steps in sequence:

[0041] (A) preparing diamond particles and cleaning;

[0042] (B) Laser ablation is used to strike the laser on the surface of the diamond particles in step (A);

[0043] (C) Adjust the position of the laser on the surface of the diamond particles, and the laser ablates several small pits on the surface of the diamond particles, so as to roughen the surface of the diamond particles.

[0044] The particle size of the diamond particles in the step (A) is 1-1000 microns, and the diameter of the laser light beam in the step (B) is 0.1-0.2 of the particle size of the diamond particles. In this embodiment, the diameter of the diamond particle is 1-1000 microns, and the diameter of the laser light spot is 0.1-0.2 of the particle size of the diamond particle. The size of the pits produced by the erosion.

Abstract

The invention relates to the technical field of superhard material preparation and discloses a laser roughening method for diamond. The laser roughening method for the diamond comprises the followingsequential steps of 1, preparing diamond particles, and conducting cleaning; 2, casting laser light to the surfaces of the diamond particles prepared in step 1 in the form of laser ablation; and 3, adjusting the position, on the surface of the diamond, of the laser light, wherein multiple small pits are formed in the surfaces of the diamond particles by the laser light through ablation so that thesurfaces of the diamond particles can be roughened. By means of the laser roughening method for the diamond, the problems that an existing diamond roughening method is long in consumed time and complex in process and causes environmental pollution are solved.

Description

technical field [0001] The invention relates to the technical field of superhard material preparation, in particular to a method for roughening diamond by laser. Background technique [0002] Diamond is commonly known as "diamond". That is what we often call the original body of diamond. It is a mineral composed of carbon element, which is an allotrope of carbon element. Diamond is the hardest substance naturally occurring in nature. It has high hardness and good wear resistance, and can be widely used in cutting, grinding and drilling. When diamond is used to manufacture cutting and grinding tools, diamond particles are generally combined with the substrate through a binder, so that the diamond is attached to the substrate. However, in the actual use process, due to the smooth surface of the diamond particles, the bond between the diamond particles and the binder is not strong, and they fall off prematurely during the cutting and grinding process, resulting in a decrease...
