In an illustrative embodiments, point can be made up of the super hard abrasive particle being attached at suitable cutter hub metal as hard in carbide alloy.This illustrative embodiments uses chemical vapor infiltration (CVI) or chemical vapour deposition (CVD) (CVD) to utilize porous or fine grained medium to fill the gap between super hard abrasive point and cutter hub.Porous or fine grained medium can be bonded to one another and be bonded to point and cutter hub by the deposition of CVI or CVD.High-temperaure coating or a series of laminated coating can be coated with subsequently as Al as a part for same process
2o
3, to provide the wearability of enhancing.
More specifically, the porous of use or fine grained medium can be survived in CVI or CVD technique.Or fine grained such as diamond or cubic boron nitride can by processes expend.Can deposit high-temperaure coating or a series of laminated coating to provide extra wearability to cutting tool during machined, this does not affect (soldering being different from metal) for the adhesion strength formed.
As shown in FIG. 1, cutting tool 10 comprises the super hard abrasive point 12 of sintering and contains the cutter hub 14 of porose 19.Cutter hub 14 can be made up of the many materials comprising tungsten-cobalt hard alloy.Cutter hub 14 can be designed to keep super hard abrasive point 12.The super hard abrasive point 12 of sintering can have multiple ultra-hard particles, and described ultra-hard particles can be selected from cubic boron nitride, diamond, diamond composites and ceramic material.Seam or gap such as gap 15, bottom and sidewall gap 16 can be there is between super hard abrasive point and cutter hub.Super hard abrasive point 12 can have or not have substrate supports thing.Substrate supports thing can be that hard metal support is as tungsten carbide supported thing.
As shown in FIG. 2, cutter 10 can comprise the super hard abrasive point 12 with tungsten carbide supported thing 20.Super hard abrasive point 12 can have polycrystal cubic boron nitride (PcBN) particle.Cutting tool 10 also can comprise the cutter hub 14 keeping super hard abrasive point 12.The non brazing material 24 of the fusing point can with at least 1000 DEG C can be deposited with filled sidewall gap 16 and gap, bottom 15.Non brazing material 24 can be at least one in such as zeolite, pottery, cubic boron nitride and diamond.Cutting tool 10 also can comprise coating, such as, impregnant bonding coat 22 on the non brazing material 24 between super hard abrasive point 24 and cutter hub.Impregnant bonding coat 22 can cover the super hard abrasive point 12 of sintering, substrate supports 20 and cutter hub 14.Impregnant bonding coat can comprise at least one of the IVB compounds of group containing C, N, O, B, such as TiN, TiC and TiCN, ZrN, ZrC, ZrCN, HfN, HfC, HfCN.
The amplification optical imagery shown in Fig. 3 illustrates, coating 22 is whole cubic boron nitride crystal 24 as TiN may cover.Coating 22 can also provide non brazing material as cBN, diamond or zeolite, the bonding between super hard abrasive point 20 and cutter hub 14.
Because non brazing material has the fusing point of at least 1000 DEG C, so can by high-temperaure coating as Al
2o
3the non brazing material that (not shown) deposited or was applied to the super hard abrasive point 12 of sintering, cutter hub 14 and is arranged between super hard abrasive point 12 and cutter hub 24.
Fig. 4 shows the illustrative methods 400 of the technique manufacturing cutting tool.Described technique comprises the steps: to provide super hard abrasive point in step 401; There is provided cutter hub in step 402; The gap between super hard abrasive point and cutter hub is filled in step 403 with non brazing material; Be coated with first in step 404 and be deposited to non brazing material.
The super hard abrasive point of sintering can be attached to cutter hub by certain methods.Then cutting tool can be placed in CVD (chemical vapour deposition (CVD)) reaction vessel, wherein remove air and replaced by the gas comprising inertia and reactive species.Metal deposition can adopt and comprise metal carbonyl or metal acetal acetonate as the gas of iron pentacarbonyl.Pottery precursors to deposit can refer to the compound containing N, C and O, its cracking at lower than the temperature of 1000 DEG C.In some illustrative embodiments, ceramic precursors to deposit can comprise such as TiCl
4, NH
3, CH
4, AlCl
3, (Me)
3al, N
2, CH
3cN, H
2, CO, CO
2or its mixture.Gas by diffusing and penetrate in gap, seam, contact gap, and be deposited on outside or inside in a device can close to the heat solid of gas on the surface.From the teeth outwards during condensation, condensation phase chemistry ground reacts thus forms the new solid-phase as the first coating.First coating can be by super hard abrasive point, the impregnant coating of cutter hub together with non brazing material binding.Such as, TiCl
4+ CH
4→ TiC solid+gas phase 4HCl.This solid-phase depends on that chemical affinity is adhesively bonded to the surface of solids.The quality (crystal perfection, density) of solid-phase depends on temperature and the affinity to the surface of solids, and they are condensate on the described surface of solids.As long as temperature is enough high and there is reactant, then forms the infiltration of new solid-phase, the technique of condensation and reaction continues to carry out.Once hole is filled, super hard abrasive point and cutter keep material surface just there will be direct coating.
Gas accessibility is spread by gas and determines, it depends on temperature and pressure.Lower pressure allows reactant gas to be more in depth diffused in seam in tool assembly and gap.Must be controlled the gas aggradation of formation solid, reaction and curing degree thus prevent from too early " obstruction " occurring in narrow gap and seam, being reduced film contact area and strength of joint thus.This needs to reduce temperature usually, or regulates the gaseous phase partial pressure of reactant.Finally, the quality of the film of formation, its degree of crystallinity and crystal orientation depend on temperature and time.If film is too fast formed and quenches, it may be of poor quality and break in film or at film-point or film-tool interface place.
Importantly, no matter the orientation in reactor, vapor precursor and the surface of solids indistinguishably react.So-called " sight line " depositing operation, may be effective unlike vapor precursor as physical vapour deposition (PVD) (PVD), and the impermeable gap of possibility and seam, significantly reduce adhered area and adhesion strength thus.
In addition, non-line-of-sight CVD coating does not need turning tool and repeatedly processes to form uniform coating.In a stove cycle, CVD is coated with the come-at-able surface of whole gas.
The gas-phase reaction that also can be regarded as CVD comprises any gas solids reaction, such as oxidation, hydration or carburizing.Solid constituent can first be adsorbed on the surface, then reaction and crystallization, or can be formed on surface before reaction and crystallization and be deposited by solid surface tension.
After can carrying out ,-CVD process is if annealing is with the quality or the film-point/film-cutter adhesiveness that improve film.
When not deviating from the scope of present disclosure, for each step in abovementioned steps 401-404, one or more step can be inserted therebetween or replace.
Although made reference to detailed description of the invention, it is evident that, when not deviating from its purport and scope, those skilled in the art can design other embodiment and variant.Be intended to appended claims to be interpreted as and comprise whole this embodiment and equivalent variations.
