Abstract
The invention relates to a kind of cube nitrided boron composite sheet. It is composed by mixing and sintering with nitrided boron powder and splice agent. The splice agent selects from any 1-3 among cobalt, molybdenum, titanium, iron, aluminium, nickel, copper, wolfram, chromium, nitrided molybdenum, nitrided titanium, nitrided zirconium, nitrided chromium, nitrided wolfram, nitrided aluminium, and aluminium trioxide. The total weight of splice agent is 2-20% of the weight of cube nitrided boron. Then add carbon powder or carbon powder and hard-alloy powder with the splice agent of 1-8% total weight into the mixture mentioned above. The splice agent also contains any 1 or 2 between silicon and boron. In the carbon powder and the hard-alloy powder, the carbon powder is 50-80%, and the hard-alloy powder is 20-50%. The invention is easy to process, and furthermore, the cutter processed has long service life.
Description
Technical field
The invention belongs to technical field of superhard material, particularly a kind of cubic boron nitride composite sheet.
Background technology
The cubic boron nitride composite sheet has good toughness and very high wear resistance, and thermostability is strong, can stand very high thermal load and does not have any danger.Therefore become a kind of new and effective cutter material of Ni-hard, high ferrochrome and converted steel and so on hard metal material with its cutter of making.The cubic boron nitride composite sheet adopts cubic boron nitride and caking agent sintering under certain temperature and pressure to form usually, wherein caking agent be selected to key factor, caking agent is mainly selected from following two class materials: (A) cobalt, molybdenum, titanium, iron, aluminium, nickel, copper, tungsten, chromium, molybdenum nitride, titanium nitride, zirconium nitride, chromium nitride, tungsten nitride, aluminium nitride, alchlor; (B) silicon, boron.Selection scheme is: (1) selects 1-3 kind raw material directly as caking agent from A, and caking agent weight is between the 2-20% of cubic boron nitride weight; (2) on the basis of (1), selection 1 or 2 kind of raw material directly add (1) as caking agent from B, and the caking agent gross weight is between the 2-20% of cubic boron nitride weight.Its production technique mixes cubic boron nitride and caking agent for (1), generally needs to mix more than 5 hours; (2) powder that mixes is packed in the mould; (3) adopt cubic apparatus hinge type hydropress, sinter molding under certain temperature and pressure.But the existing workability of cubic boron nitride composite sheet own is poor, can not use needs directly it to be cut into desired shape according to the user, can only with instrument composite sheet directly be broken into two with one's hands earlier, regrinds into desired shape.So operation is very easily broken composite sheet off with the fingers and thumb badly and is caused waste product, and yield rate is low; Composite sheet is moved the rear surface unfairness, and stock removal is big in the processing, not only directly influence into cutter speed, and processing charges is big, and efficient is low.
Summary of the invention
The object of the invention is to provide a kind of cubic boron nitride composite sheet that is easy to process.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: the cubic boron nitride composite sheet, form by boron nitride powder and caking agent mixed sintering, caking agent is selected from any 1-3 kind in cobalt, molybdenum, titanium, iron, aluminium, nickel, copper, tungsten, chromium, molybdenum nitride, titanium nitride, zirconium nitride, chromium nitride, tungsten nitride, aluminium nitride, the alchlor, the caking agent gross weight is the 2-20% of cubic boron nitride weight, adds carbon dust or carbon dust and the cemented carbide powder of caking agent weight 1-8% in said mixture.
Caking agent also contains in silicon, the boron a kind or 2 kinds.
In carbon dust and the cemented carbide powder, carbon dust accounts for 50-80%, and cemented carbide powder accounts for 20-50%.
Product processing technique of the present invention is with existing technology.The present invention adds a certain proportion of carbon dust or carbon dust and cemented carbide powder in cubic boron nitride and adhesive mixture, the electroconductibility of the feasible cubic boron nitride composite sheet of making strengthens greatly, can pass through Wire EDM, directly cut into user's desired shape, thereby improved yield rate and rate of utilization, reduced tooling cost.More because the adding of carbon has increased the oilness of material and the hole that dispels the heat, and the workpiece to be machined glossiness is higher, can reach with the effect of car for mill, can improve 9-13% the work-ing life of cutter.(user 1), Shanxi (user 2), the contrast use of Jilin (user 3) three producers the results are shown in following table in Shandong for composite sheet of the present invention and common composite sheet
| Composite sheet | The workpiece to be machined surface smoothness | The workpiece to be machined number | Durability (work-ing life) contrast | |
| The user 1 | Common | 1.6 | ?1600 | Improve 12.5% |
