Abstract

The present invention relates to a diamond surface coating glass, coating diamond and plating titanium composite structure and the manufacturing method thereof. The surface of a diamond is provided with a glass layer. A diamond layer is arranged on the glass layer. The surface layer of the diamond layer is provided with a titanium layer. The manufacturing method comprises the following steps: step 1, the surface of the diamond is coated with glass; step 2, fine diamonds are coated on the glass layer; step 3, the surfaces of the fine diamonds are plated with a layer of titanium by using a vacuum micro-evaporating method. The diamond of the present invention, which is treated by composite coating and plating, has the advantages of enlarged volume, ball-like shape and even distribution of diamond grinding particles. Simultaneously, the combining strength and the holding force of the diamond and a basal body are big, which prevents the grinding particles from dropping off soon. The diamond coated with fine diamonds becomes a special diamond grinding particle having two kinds of granularity performance of rough and fine particles. When in use, the diamond can achieve the composite grinding effect of rough and fine grinding particles. The diamond is used for the manufacture of resin binding agent grinding tools to process workpieces of which the quality is particularly required.

Description

A kind of composite structure of diamond surface coated with glass, diamond and titanium layers and manufacture method

Technical field

The present invention relates to a kind of composite structure of diamond surface coated with glass, diamond and titanium layers and manufacture method.

Background technology

Diamond is very extensive in industrial application, can make multiple instrument such as cutter, emery wheel, grinding tool etc., because the characteristic of diamond itself, combine very difficult with other material, so the matrix from instrument comes off easily, causes the work-ing life of instrument low, production cost increases.

Summary of the invention

The objective of the invention is to improve the prior art diamond combines the shortcoming of difficulty and a kind of composite structure of diamond surface coated with glass, diamond and titanium layers and manufacture method is provided with other material.

For achieving the above object, the present invention takes following design: diamond surface is compounded with a glass coating; On described glass coating, be compounded with a diamond layer; Be compounded with a titanium layer on the top layer of described diamond layer.

A kind of composite structure of diamond surface coated with glass, diamond and titanium layers manufacture method comprises following step;

Step 1: in the diamond surface coated glass,

Step 2: on above-mentioned glass coating, apply melee,

Step 3: adopt the little evaporation of vacuum to be plated in above-mentioned melee surface and plate one deck titanium.

Advantage of the present invention, the diamond that compound coating of this process and plating are handled, volume increases, be bordering on spherical, the grinding tool of manufacturing, diamond abrasive grain is evenly distributed, diamond and high base strength and hold height prevent the abrasive particle early fallout simultaneously.The diamond of the melee that applies becomes a kind of adamantine special abrasive particle of two kinds of granularity performances of thickness that has, and uses it can reach the composite grinding effect of thickness abrasive particle.The grinding tool that uses it to make resinoid bond is processed with the workpiece of particular requirement, can satisfy user's special requirement.

Embodiment

Embodiment 1: as shown in Figure 1, there is a glass coating 2 on diamond of the present invention 1 surface; One diamond layer 3 is arranged on described glass coating 2, one titanium layer 4 is arranged on described diamond layer 3 top layers.

Embodiment 2: diamond 1 is a particulate state, and irregular scraggly type looks surface is arranged, and described glass coating 2, diamond layer 3 and titanium layer 4 form composite bed, parcel diamond 1 according to diamond 1 irregular scraggly type looks surface.

Embodiment 3: a kind of composite structure of diamond surface coated with glass, diamond and titanium layers manufacture method comprises following step;

Step 1:, use conventional, electric-resistance baking oven equipment in the diamond surface coated glass; As follows step by step;

Step 1) is placed on rosin 120g, alcohol 120ml rosin is melted fully;

Step 2) spreads placement out after diamond is fully mixed thoroughly with the proportioning of 1000CTS/60ml with above-mentioned solution, nature is dried; With glass powder, such as applying the glass powder that granularity is diamond use 230/270～270/325# of 80/100# than the thin 5-6 of a diamond grain size number; Sodium silicate: Na ₂₀N.SiO ₂.nH ₂O;

Step 3) is fully mixed glass powder and diamond thoroughly tinning with 4: 1 ratio;

Step 4) is preheating to 110 ℃ with baking oven, and the jar of step 3) was placed in the baking oven baking 2 hours, takes out cooling;

Step 2: on above-mentioned glass coating, apply melee, use equipment: resistance furnace, as follows step by step;

Step 1) will apply the diamond and the diamond of glass and mix tinning thoroughly in 5: 1 ratio, be placed in the special resistors stove, be warmed up to 600 ℃ after the insulation 1 hour, again temperature is risen to 800 ℃ after the insulation 1 hour after powered-down; Get final product with the diamond than the thin 5-6 of a diamond grain size number, promptly the diamond of 80/100# uses the melee powder of 230/270～270/325#;

Step 2) treat to come out of the stove after diamond is with the stove naturally cooling, sieve good finished product;

Step 3: adopt the little evaporation of vacuum to be plated in above-mentioned diamond surface and plate one deck titanium;

Equipment: cover of titanizing vacuum oven and vacuum unit;

1, technical process and parameter: in the special-purpose jar of packing into behind diamond and the titanium valve uniform mixing, be placed in the vacuum furnace chamber; Open the vacuum unit and be warming up to the temperature (120 orders are 745 ℃ with thick diamond, and 120 orders are 780 ℃ with thin diamond) of setting, be incubated 1 hour postcooling to 250 and ℃ close the vacuum unit; Treat to cool off fully the back jar is taken out, get product after sifting out diamond;

2, the granularity of titanium valve, proportioning, dosage, thickness of coating:

1) titanium valve granularity 120 orders with thick diamond with 230 orders with thin titanium valve, 120 orders with thin diamond with 60 orders with thick titanium valve;
