Description
Technical field
This disclosure relates to brill to comprising sintered carbide with the improvement of cutting mold insert, this brill ground with cutting mold insert for bore with drill bit for example as rotary brill use together with percussion drill bit (for example, as hammer drill) by tooth-wheel bit.This disclosure also relate to comprise one bore with drill body and according to this disclosure be arranged at least one on this drill body bore with cut mold insert one brill use drill bit.
Background of invention
Boring ground uses (or boring) drill bit to be usually used in exploration, mining and the excavation of oil and natural gas.This type of bores ground drill bit can comprise rotatable or fixing cutting element.For example, Fig. 1 shown comprise the drill body that contains multiple rotatable cutting elements 11 the typical rotary brill of one by tooth-wheel bit 10, be commonly called " rotary gear wheel (rotary cone) ".Cutting mold insert 12 can be made up of sintered carbide, be installed in cutting mold insert dimple, and these cutting mold insert dimples are positioned on each the outside surface in these rotatable cutting elements 11.Several can be cut to mold insert 12 is arranged in the different predetermined position on these rotatable cutting elements 11 to optimize this brill with the stock removal action of drill bit 10.
Bore ground with typically becoming along with the wearing character of the cutting mold insert of this drill bit in work-ing life of drill bit.Improve that to bore ground a kind of technology of drilling life of bit be to adopt the brill be made up of the material of improved combination with intensity, toughness and wearability with cutting mold insert.What the brill ground of many routines used with drill bit is the cutting element of being made up of sintered carbide, and this sintered carbide is a kind of hard particulate material of sintering.For the selection of the sintered carbide of this type of application be based on: these materials provide the combination having a great attraction of intensity, fracture toughness property and wearability, these characteristics to bore with validity and the economic benefits of drill bit be very important.Sintered carbide is the mixture that comprises a discontinuous disperse phase, and this discontinuous disperse phase typically comprises the hard particles that contains the carbide that belongs to IVB, the VB of the periodic table of elements and one or more transition metal of group vib.For example, these transition metal comprise: titanium (Ti), vanadium (V), chromium (Cr), zirconium (Zr), niobium (Nb), molybdenum (Mo), hafnium (Hf), tantalum (Ta) and tungsten (W).The hard particles of this disperse phase be by a kind of external phase of metal adhesive bond or " sintering " together, this metal adhesive typically comprises one or more in the following: cobalt, cobalt-base alloy, nickel, nickelalloy, iron and iron alloy.In these different possible hard particles-metal adhesive combinations, that sintered carbide based on wolfram varbide (WC) is as disperse phase hard particles and use cobalt (Co) or nickel (Ni) as metal adhesive (, being respectively WC-Co base sintered carbide and WC-Ni base sintered carbide) boring conventional in applying.
Applying and the mechanical characteristics of wanting of overstating depends on two microstructure parameters to a great extent boring of sintered carbide,, (i) average hard particles size and the (ii) hard particles in this sintered carbide and/or the weight or meausurement mark of metal adhesive.Generally, when disperse phase hard particles size reduces and/or when this metal bonding agent content reduces, the hardness of sintered carbide and wearability increase.On the other hand, when disperse phase hard particles size increases and/or in the time that this metal bonding agent content increases, the fracture toughness property of sintered carbide increases.Therefore, in the time selecting a kind of sintered carbide grade for any application, between wearability and fracture toughness property, there is a kind of balance.In the time that wearability increases, fracture toughness property typically reduces, and vice versa.
Fig. 2 A-2E shown with rotary brill with a series of different shapeies and the design of the normal sintering carbide cutting mold insert using together with tooth-wheel bit.Bore the shape of the possible arcuate part that is characterized as this mold insert of ground cutting mold insert.For example, obtainable shape comprises: avette (Fig. 2 A), trajectory shape (Fig. 2 B), chisel-shaped (Fig. 2 C), multiple arch shape (Fig. 2 D) and taper shape (Fig. 2 E).The selection of shape and the sintered carbide composition (, grade) that uses is subject to for example needing being holed or the impact of the rock type excavated.Irrelevant with shape or size, bore ground cutting mold insert and typically comprise a working portion and a body part.For example, the ground of the brill shown in Fig. 2 A comprises working portion 32 and the body part 34 of arch with cutting mold insert 30.Equally, for example, the brill ground shown in Fig. 2 B comprises cutting tip 42 and the body part 44 of trajectory shape with cutting mold insert 40.Stock removal action is to be undertaken by this working portion completely or mainly, and this body part provides support this working portion.Generally, this body part most of or be all embedded in drill body, and this body part is typically arranged on drill body by pressure fitted or is otherwise fixed in the cutting mold insert dimple providing on this drill body.
As described above, this drilling/stock removal action can be at least mainly assigns to provide by an operate portions of cutting mold insert by boring.First area working portion, that start to wear away of boring ground cutting mold insert is upper part of this working portion, particularly top.When boring while starting to flatten with the top of working portion of cutting mold insert, stock-removing efficiency significantly reduces, and this is that rock and soil layer are to be removed by the rubbing that rubs more because of different from more effective stock removal action.In the time that this rubbing that rubs is done to continue, may produce a large amount of heats due to the increase of the friction between material and cutting mold insert, cause thus the heat effect of the multiple parts to this cutting mold insert to increase.Exceed threshold value if sintered carbide bores the temperature of any part of ground cutting mold insert, may start to occur thermal crack in the interface of these hard particles and metal adhesive.The thermal cycling of these article has aggravated spreading of thermal crack.Fracture propagation may cause the fracture of cutting mold insert, and this may force changes cutting mold insert or whole drill bit.A drill string is taken out from boring so as for example to touch and repair or place a cutting mold insert that contains fracture brill with drill bit, drilling process and increased significant expense to this drilling process has significantly slowed down.

The some terms that use in this explanation and in claim have following implication.
As used herein, term " sintered carbide " refers to a kind of matrix material, and this matrix material comprises a discontinuous disperse phase that contains multiple hard particles and a kind of external phase of soft metal adhesive relatively.In the sintered carbide of many routines, the hard particles of this disperse phase comprises transition metal carbide, and wherein this transition metal is to be selected from titanium for example, vanadium, chromium, zirconium, hafnium, molybdenum, niobium, tantalum, tungsten, wherein two or more sosoloid and two or more solution wherein.This metal adhesive typically comprises at least one in cobalt, cobalt-base alloy, nickel, nickelalloy, iron and iron alloy.By the hard particles bonding of these dispersions or " cohering " together, and this mixture shows the favourable combination of the physical property of this discontinuous phase and external phase to this metal adhesive.Fig. 3 is a kind of Photomicrograph of microstructure of representational sintered carbide.These are the wolfram varbide hard particles disperseing compared with bright area, and should be the successive zones of co binder that these wolfram varbide hard particles are bonded together compared with dark areas, form thus this mixture.In multiple non-limiting examples, the metal adhesive of this sintered carbide can also comprise one or more additives, and this additive is selected from: chromium, molybdenum, boron, tungsten, tantalum, titanium, niobium, silicon, aluminium, copper and manganese.In some non-limiting example, the metal adhesive of sintered carbide can comprise total amount these additives up to 20 weight percents, based on the gross weight of this binding agent.In other non-limiting examples, the metal adhesive of sintered carbide can comprise that total amount is up to 15 weight percents, up to 10 weight percents or up to these additives of 5 weight percents, based on the gross weight of this binding agent.Will be appreciated that this disperse phase and this metal adhesive all can comprise inevitable impurity.
Numerous sintered carbide types or " grade " are to be produced by different parameters, and these parameters can comprise the composition of the material in this disperse phase and/or external phase, the mean size of hard particles and/or the volume fraction of this discontinuous phase and external phase of this disperse phase.The sintered carbide that comprises tungsten carbide particle disperse phase and cobalt or cobalt-base alloy binding agent is commercial most important common obtainable sintered carbide grade.Conventional sintered carbide grade is obtainable as powder (being commonly referred to " cemented carbide ").By using for example conventional compression and sintering technology or for produced other known technologies of sintered carbide by precursor cemented carbide grade, these powder processing can being become to final integral form.
Comprise that the normal sintering carbide grade of a discontinuous disperse phase of tungsten carbide particle and a co binder external phase has represented the favourable combination of ultimate tensile strength, fracture toughness property and wearability.As known in the art, " fracture toughness property " refers to that material absorbed the ability of energy and viscous deformation before fracture." toughness " is the below area from initial point to rupture point proportional (referring to McGraw-Xi Er scientific and technical terminology dictionary (the 5th edition, 1994)) and can estimating by the mechanical test technology with known to stress-strain curve." wearability " refers to that material bears the ability of surface damage.Wearing and tearing relate generally to the loss gradually of the material of these article that cause due to relatively moving between article and surface in contact or substrate.Referring to the plainly-packed version of metals handbook (the 2nd edition, 1998).
Some non-limiting example of boring ground cutting mold insert described here comprises a working portion.As used herein, " working portion " refers to brill by the following part of cutting mold insert, this part mainly contact need by this brill rock, earth or the other materials removing or separate with drill bit, this brill ground is with this cutting mold insert has been installed on drill bit.Compared with this working portion, bore ground cutting mold insert and can also comprise one " body part ", as used herein, body part refers to this brill by cutting part mold insert, that support this working portion.This body part and working portion can be but need not to be single brill with multiple regions of cutting mold insert.Will be understood that according to brill of the present invention in some embodiment with cutting mold insert, between the working portion of this cutting mold insert and body part, can not there is not dividing line clearly.But, in this type of embodiment, one of skill in the art will recognize that the difference between these parts, be that this working portion is adapted to the set function of carrying out this cutting mold insert for main, and this body part will be adapted to for this working portion of main support.Alternatively, this working portion and body part can be formed and otherwise attached or be bonded together regularly by different materials, make like this this body part in the time using this cutting mold insert provide necessary support to this working portion.
General understand, determined to a great extent to bore with the characteristic of the sintered carbide of (therefore also have these these brills that cut mold inserts have been installed on it with drill bit) overall performance of cutting mold insert be wearability and fracture toughness property.In order to optimize brill by the performance of cutting mold insert, desirable is to obtain the highest fracture toughness property for the wearability of given level, and vice versa.As indicated above, these characteristics of the wearability of sintered carbide and fracture toughness property are subject to the impact of two parameters of this material microstructure to a great extent,, the weight or meausurement mark of average hard particles size and hard particles and/or metal adhesive.Generally, when average hard particles size reduces and/or when the weight or meausurement mark of the metal adhesive of this sintered carbide reduces, hardness and wearability increase.On the other hand, when average hard particles size increases and/or when the weight or meausurement mark of the metal adhesive of this sintered carbide increases, fracture toughness property increases.Therefore, it is believed that, select for any brill apply sintered carbide grade time, between wearability and fracture toughness property, inevitably to make balance.
Wearability in some conventional sintered carbide and the balance between fracture toughness property in table 1 and Fig. 4, are shown.Table 1 provides the WG-Co base sintered carbide grade of a series of routines, is denoted as grade A to grade L, and these grades are usually used in brill with cutting in mold insert and being commercially available from the ATI Firth Sterling company in Houston city, Texas.Table 1 has also been listed following content for each grade: the commercial grade title that ATI Firth Sterling company is used, average WC particle size, co binder content (based on the gross weight of this sintered carbide), hardness and density.In table 1, list cobalt contents time gross weight based on sintered carbide weight percent.The surplus of each grade of listing in table 1 is tungsten carbide particle.Listed sintered carbide grade comprises the WC particle of mean diameter within the scope of about 4 to about 8 μ m, about 8 to the co binder content in about 17 weight percentage ranges, and surplus has formed WC particle.Fig. 4 is a chart that the relation between wearability and the fracture toughness property of the sintered carbide grade A-L listing in table 1 is plotted to curve.By assessing fracture toughness property by a kind of testing method, this testing method is equal to ASTM B771-87 (2006) " standard method of test [Standard Test Method for Short Rod Fracture Toughness of Cemented Carbides] of the quarter butt fracture toughness property of sintered carbide " substantially.Wearability is to assess according to ASTM B611 – 85 (2005) " standard method of test [Standard Test Method for Abrasive Wear Resistance of Cemented Carbides] of sintered carbide wearability ".
Table 1
As what confirmed according to the minimum matched curve that in Fig. 4, the data point about grade A to L is drawn, in the time that wearability increases, fracture toughness property reduces, and vice versa.Equally, as being clear that in Fig. 4, all data points of describing the fracture toughness property of every kind in sintered carbide grade A-L and wearability value are all positioned at this minimum matched curve relative Zhai district band around.While having provided being related to shown in Fig. 4, metallurgist and design engineer be selecting when boring the sintered carbide grade of applying, be faced with must be in wearability and fracture toughness property one or another one on the dilemma of making concessions.
Ladies and gentlemen contriver of the present invention makes great efforts to improve sintered carbide brill by the performance of cutting mold insert by revising the composition of this sintered carbide.For example, with reference to the sintered carbide grade of Fig. 4, ladies and gentlemen contriver of the present invention sums up: if (the independent data point in Fig. 4 can be shifted eastwards, increase wearability and fracture toughness property without any loss) and/or displacement is northwards (, increase fracture toughness property and wearability without any loss), can significantly strengthen comprise these sintered carbides brill by the performance of cutting mold insert.Therefore, the arrow in Fig. 4 shows a desirable direction, can be by these independent data points (representing the wearability of these independent grades and the combination of fracture toughness property) at the party's upward displacement to strengthen the property.More generally, ladies and gentlemen contriver of the present invention has attempted confirming that the amendment of composition to sintered carbide grade does not reduce fracture toughness property and/or increases fracture toughness property and do not reduce wearability to increase wearability.
Ladies and gentlemen contriver of the present invention finds, comprise sintered carbide (wherein to added in the metal adhesive of this sintered carbide a kind of platinum metals for example ruthenium as alloying additive) brill ground cutting mold insert with respect to the identical sintering grade that lacks this additive shown to brill apply and overstate that want, obvious improved characteristic.For example, ladies and gentlemen contriver of the present invention determined with test by experiment, and the average WC particle size based on suitable with some conventional carbide grade listed in upper table 1 is with Co content but be modified and comprised that platinum metals ruthenium provides remarkable more excellent wearability and the combination of fracture toughness property are provided compared with corresponding conventional grade as the WC-Co base sintered carbide of the alloying additive of the cobalt-based metal adhesive of sintered carbide.
Prepare in following table 2 experiment listed, that be denoted as R-1 to R-4 with containing ruthenium sintered carbide.The cobalt that table 2 is listed and ruthenium content are the weight percents of the gross weight based on sintered carbide.Be usually used in producing standard press and the sintering technology of the sintered carbide for using cutting mold insert by use with boring, prepared each grade R-1 to R-4 in substantially the same mode.In the process of each of preparing these experimental grade, WC-Co, cobalt and ruthenium powder blend are provided to the powder blend of homogeneity, this blend has WC particle, cobalt and the ruthenium of desired ratio.Then about 20 by using, the compaction pressure of 000psi is consolidated into green compact by a part for this powder blend in a rigid tool.These green compact are carried out to sintering and under this outlet temperature, maintain about 90 minutes in an outlet temperature is the overpressure sintering furnace (also referred to as " sintering-hot isostatic pressing " stove) of 1400 degrees Celsius.This sintering step causes the phase mutual diffusion of ruthenium and cobalt, thereby has produced a metal adhesive external phase that comprises cobalt and ruthenium, and a disperse phase of this external phase and hard tungsten carbide particle is bonded together.In Fig. 6 A-D, show respectively the microstructure of experimental grade R-1 to R-4.Dark space in every Photomicrograph is the tungsten carbide particle that forms the disperse phase of this material, and clear zone has represented the co binder containing ruthenium of this material.Table 2 provides about the average WC particle size of experimental grade R-1 to R-4 and the information of composition.
Table 2
Prepare suitable test sample book and tested its fracture toughness property and wearability by the blank through sintering of experimental grade R-1 to R-4.Table 3 has been listed the mechanical characteristics of measuring of these experimental grade, and Fig. 5 comprises the data point R-1 to R-4 that the relation between the wearability of corresponding experimental grade and fracture toughness property is plotted to curve.Assess fracture toughness property by the testing method that uses one to be substantially equal to ASTM B771 – 87 (2006).Assess wearability according to ASTM B611 – 85 (2005).Fig. 5 also comprises the curve occurring in the data point of conventional grade A-L and Fig. 4.The improvement in performance being realized containing the experimental grade of ruthenium by these is obvious in Fig. 5.Each data point of these experimental grade is offset away from the minimum matched curve of being drawn by the data point of these conventional grades significantly.For example will be appreciated that, the minimum matched curve producing based on these four data points of R-1 to R-4 in Fig. 5 should be arranged in the curve position of direction skew being northeastward associated from the data point with normal sintering carbide grade of Fig. 5.Therefore, about the minimum matched curve of data point R-1 to R-4, for any given fracture toughness property, the wearability being associated will significantly be greater than shown in Fig. 5 for the wearability on the curve of these conventional grades.Equally, about the minimum matched curve of data point R-1 to R-4, for any given wearability, the fracture toughness property being associated will significantly be greater than shown in Fig. 5 for the fracture toughness property on the curve of these conventional grades.
Table 3
Therefore, add platinum metals ruthenium allow to obtain fracture toughness property at least with conventional grade quite but wearability larger sintered carbide grade, vice versa.Therefore, for example, in the situation that fracture toughness property does not have correspondence to reduce, can realize larger wearability, and can realize large fracture toughness property in the situation that wearability does not reduce.The contained embodiment that bores ground novel sintered carbide grade in mold insert with cutting by this cutting mold insert of increase and this brill do as a whole work-ing life with drill bit.This cuts by reducing the frequency that mold insert is changed, and the pull-out of drill string is still less occurred, and has reduced thus stop time and cost.
Correspondingly, one aspect of the present invention be for a kind of brill that comprises sintered carbide with cutting mold insert, this sintered carbide comprises a kind of metal adhesive that contains ruthenium.Ladies and gentlemen invent people and determine, add ruthenium and have improved these performances of cutting mold inserts, shown in experiment as previously discussed to this metal adhesive.Ladies and gentlemen contriver of the present invention is told in work before, and other platinum metals rhodium, palladium and platinum and element rhenium (being arranged in the adjacent columns of periodictable) can have similar and effect platinum metals ruthenium.Correspondingly, the result of the test of carrying out about interpolation ruthenium based on ladies and gentlemen contriver of the present invention, this disclosure has also been considered can be to adding one or more in ruthenium, platinum, palladium, rhenium and rhodium in the metal adhesive that is included in brill with the sintered carbide in cutting mold insert, to realize these advantages discussed herein.
For further show scope of the present invention, in table 4, provide can be included according to brill of the present invention by different possible (prophesy) non-limiting example of the sintered carbide in cutting mold insert and drill bit, be numbered example 1-10.In table 4, listed all values is the weight percent of the gross weight based on sintered carbide.The particle that forms the disperse phase of these sintered carbides comprises wolfram varbide (WC), titanium carbide (TiC), tantalum carbide/niobium (Ta, NbC) and/or chromium carbide (Cr
