Embodiment 1

[0029] The diamond is coated with a resin film by using the vacuum micro-evaporation method in the prior art, and the heating temperature is 900°C. The coated diamond powder becomes the first diamond.

[0030] The service life of the grinding wheel produced with the first diamond powder is 35 hours. Observed with a microscope, the diamond coating has incomplete parts and is in an uneven state.

[0031] In each of the following embodiments, the diamond is subjected to the same steps of vacuuming and exhausting residual air, that is, steps a and b in the summary of the invention, and there are differences in the subsequent processes of each embodiment.

Embodiment 2

[0033] c. Diamond surface coating

[0034] The diamond powder after handling in the above-mentioned steps b is placed in the following process for processing:

[0035] Cathode target material: ABS resin sheet target material;

[0036] Voltage: 400V;

[0037] DC current: 1.0A;

[0038] Deflection voltage: 140V;

[0039] High-purity argon gas flow: 12sccm;

[0040] Working time: 10800s;

[0041] Temperature: Temperature 140°C;

[0042] Movement method: diamond powder movement;

[0043] After the above steps, the second diamond with a resin film structure on the surface can be obtained.

[0044] The service life of the grinding wheel produced with the second diamond was 58 hours. Observed with a microscope, the diamond coating is complete and uniform.

Embodiment 3

[0046] c. Diamond surface coating

[0047] The diamond powder after handling in the above-mentioned steps b is placed in the following process for processing:

[0048] Cathode target material: ABS resin sheet target material;

[0049] Voltage: 400V;

[0050] DC current: 1.2A;

[0051] Deflection voltage: 160V;

[0052] High-purity argon gas flow: 12sccm;

[0053] Working time: 12000s;

[0054] Temperature: Temperature 160°C;

[0055] Movement method: diamond powder movement;

[0056] After the above steps, the third diamond with a resin film structure on the surface can be obtained.

[0057] The service life of the grinding wheel produced by the third diamond is 60 hours. Observed with a microscope, the diamond coating is complete and uniform.

Abstract

The invention relates to the technical field of diamond surface treatment, particularly a manufacturing method of a resin film plated on a diamond surface, which is performed in a diamond vacuum plating machine. The method comprises the following steps: a. vacuumizing: putting diamond in a plating chamber of a vacuum ion plating machine, and vacuumizing the plating chamber to 2*10<-3>Pa; b. diamond surface cleaning: carrying out cleaning treatment on the diamond for 30 minutes by using a 5KV ion source; and c. diamond surface plating: treating the diamond powder treated by the step b in the following technique: the target cathode uses an ABS (acrylonitrile-butadiene-styrene) resin sheet target, the voltage is 400V, the direct current is 1.0-1.2A, the deflecting voltage is 140-160V, and the like. The method can easily plate a resin film on the diamond, and has the advantages of high plating stability and high plating compactness. Besides, the plating technique also has the advantage of complete and uniform plating.

Description

technical field [0001] The invention relates to the technical field of diamond surface treatment. Background technique [0002] The material coated with a resin film on the surface of the diamond has a special purpose. The sawing or grinding products made of diamond with a resin film can protect the diamond from graphitization erosion under high temperature conditions, and form a compound bond to strengthen The carcass holds the diamond, thereby reducing the threshing phenomenon. [0003] In the prior art, the vacuum micro-evaporation plating method is used to coat the resin film on the diamond surface. This method has the disadvantages of harsh process conditions, heating, and difficult realization; in addition, the resin film plated by this method also has the characteristics of dense The disadvantages of poor durability and not firmness affect the effect of diamond installation on sawing or grinding products. Contents of the invention [0004] The purpose of the prese...
