Abstract
The present invention relates to an additive of a diamond product. The additive has the advantages of low sintering temperature, high bonding strength of a blank body, small friction coefficient, etc. Besides, the present invention has good adhesiveness for diamonds, and is not easy to oxidize. The cost of the additive is low, the service life of a product can be usually improved by 20% to 30%, and the sharpness of the product can be improved by 35% to 55%. The additive can be widely applied to diamond products, such as diamond drill bits, diamond saw blades, diamond wheels, diamond rollers, diamond grinding wheels, etc., and can also be used as additives in other sintered metal products. Consequently, the additive has a wide application prospect.
Description
The present invention relates to a kind of additive of diamond composition.
In the diamond composition manufacture process, powder additive commonly used have copper, cobalt, nickel, iron, etc., add zinc, tin, low melting point powder constituents such as 663, these powder generally will just can reach the tyre-e/or performance requirement at 850～900 ℃ of following sintering, and diamond then obviously reduces intensity at sintering more than 850 ℃.Therefore, seeking a kind of sintering temperature in 800～850 ℃ of scopes, neither influence adamantine intensity, the additive than the diamond composition of high bond strength is arranged again, is task extremely to be solved in the superhard material development.
Advantages such as purpose of the present invention aims to provide a kind of additive of well behaved diamond composition, and this additive has the reduction sintering temperature, improves the carcass bond strength, and coefficient of friction is little have good adhesive force and are difficult for oxidation diamond.
The additive of diamond composition involved in the present invention, its chemical analysis are (weight): copper 80%～90%, and tin 3%～5%, zinc 2%～4%, lead 1%～3%, titanium 2%～4%, aluminium 2%～4%, surplus is trace impurity.
In the additive of the present invention, because copper has higher binding strength, therefore copper is decided to be matrix material, content is 80%～90%.Tin, zinc, plumbous effect mainly are the fusing points that reduces powder additive, improve the comprehensive mechanical performance of copper matrix.The effect of titanium mainly is to improve wearability, further reduces fusing point simultaneously.Aluminium is transition elements, improves additive to adamantine adhesiveness, makes the diamond difficult drop-off, also improves the toughness of this powder additive simultaneously.
The production technology of additive for diamond product of the present invention is as follows: the raw material proportioning, and------dust (nitrogen protection)------(200#)------(composition detection)---vacuum packaging---dispatches from the factory to contain the oxygen detection in screening in oven dry (200 ℃) in intermediate frequency furnace melting (1200 ℃).
The application characteristic of powder additive of the present invention is as follows:
1. adhesion strength is apparently higher than tin, zinc, powder such as 663, and coefficient of friction is little, and the carcass bending strength is higher by about 1/4 than typical additives, can improve product service life 20%～30%, improves sharpness 35%～55%.
2. the powder fusing point is 780 ℃, and sintering temperature is 800～850 ℃, owing to reduced sintering temperature, thereby has avoided that adamantine intensity obviously descends in the sintering process.
3. proportion 8.6, and the pine dress is than the same with 663 powder.
4. the liquid phase good fluidity helps the product uniformity.
5. be difficult for oxidation, be convenient to storage.
6. because of containing transition elements, improved additive, thereby further improved its service life and sharpness adamantine adhesiveness.
7. under a stable condition, use this additive can not have the design of cobalt prescription, help reducing cost.
8. this additive addition generally is no more than 20%, and addition too much can make sharpness too high, and reduces toughness, influences the life-span.
9. the hot pressing characteristics of this powder additive are that pressure appreciates maximum in the time of 780 ℃.
The on-the-spot operating position of additive for diamond product of the present invention following (comparing with the following life-span of cost) with sharpness:
Place processing object product does not have additive adding of the present invention Cenxi, additive of the present invention Guangxi and cuts road A granite Ф 1.6M cutter head 100m

Additive for diamond product of the present invention is applied widely, not only can be used for diamond composition, as diamond bit, diamond saw blade, skive, diamond roller, diamond-impregnated wheel etc., also can be used as the additive in other sintered metal product.Therefore, this additive has broad application prospects.
