In the documents such as the microstructure and property of powdered metallurgical material ", high rigidity high-strength tenacity ferrous based powder metallurgical high-abrasive material all there are no
Report.This is one of background technology.
The two of background technology are that the present invention is directed to the wear-resisting of the wear-resistant structural member demand that China is used in the market
Material and research and develop.Blade of a sword plate, liner plate, tup and the high speed impact mould such as used on disintegrating apparatus.Particularly on disintegrating apparatus
The wear-resistant structural material used is that metallurgy and foundry part is many, and most of material is potassium steel and rich chromium cast iron.Cast due to smelting
The wearing piece of method production is made, thick, loose component segregation, tissue, shrinkage cavity, stomata, crackle and slag inclusion inevitably be present
The defects of, it is ordinary affair to cause casting fracture.And these high-abrasive materials have been avoided and referred to about important performance in national standard
Mark.For example, in GB/T5680-2010 " Hadfield steel casting " standard, hardness this important performance indexes are just avoided.
Therefore castingin TM52 steel bonded carbide can only could be used on its working face.In GB/T8263-2010, " wear-resistant white is cast
In the standard of part ", obdurability performance indications are avoided.Due to no obdurability, it can only be used as wear-resistant castingin block.It is above-mentioned
The performance indications that standard is avoided, it is because current melting and casting production technology and tooling device is unable to reach or can not obtained
Go out an ideal value to state.And the wearing piece of powder metallurgy process production is used, the deficiency of this respect can be made up, fills up it
Blank.So under the conditions of above-mentioned background technology, it is high-strength secondary alloyed preparation high rigidity has been invented using powder metallurgy process
Toughness P/m Iron Base high-abrasive material.
The three of background technology are that principle of the invention is alloying theory, is proposed herein under theoretical guidance with secondary conjunction
Aurification come meet powder metallurgy process production ferrio wear-resistant material requirement.It is meanwhile " wear-resistant also for GB/T26652-2011
In composite castingses ", imbedding hard alloy block is expensive, and castingin 2 wear-resistant white cast block hardness low (only HRC56) etc. is asked
Topic.And develop the secondary alloyed preparation high rigidity high-strength tenacity P/m Iron Base high-abrasive material of the present invention.
The content of the invention
It is an object of the invention to provide a kind of secondary alloyed preparation high rigidity high-strength tenacity ferrio wear-resistant material.As before
It is described, the substitution castingin wear-resistant white casting block that obdurability is poor, hardness is low, while the also ferrio wear-resistant material of realization low cost
Substitution or part substitute expensive steel bonded carbide.
The technical scheme is that, there is provided a kind of secondary alloyed preparation high rigidity high-strength tenacity ferrio wear-resistant material
Method, comprise the following steps：
First time alloying (pre-alloyed)：(1) by after raw material melting, alloy powder A, the alloy are prepared with water fog method
The weight/mass percentage composition of each element is in powders A：Cr 18%~23%, Mo 0.8%~1.8%, 0.6%~% of Ni
1.5%th, Ti 0.3%~0.8%, Si 0.4%~1.0%, V 0.6%~1.2%, C 2.4%~2.9%, Fe are surplus；
Second of alloying：(2) the powder B of 7~10 mass parts and the alloy powder A ball millings of 90~93 mass parts are mixed
Material, forming agent is added, blank is made, then sintered obtain the ferrio wear-resistant material；
The weight/mass percentage composition of each composition is in the powder B：Cu 12%~24%, Ni 12%~20%, Mo 9%
~15%, Mn 6%~12%, TiC 15%~25%, Fe are surplus.
Further, the forming agent is rubber solutions.
Further, the particle diameter of the alloy powder A is less than 75 microns.
Further, the particle diameter of the TiC powder in the powder B is less than 0.5 micron.
Further, in the powder B, Mn is added in the form of MnFe master alloyed powders.
Further, in the step (2), the temperature control of sintering is：First forming agent is sloughed in heating；1080 are warming up to again
~1120 DEG C, heat-preserving deoxidizing reducing metal；1150~1270 DEG C are continuously heating to, alloying is realized in insulation；Finally cooling obtains
The ferrio wear-resistant material.
Further, in the step (1), the temperature of melting is 1450~1550 DEG C.
The present invention further provides the ferrio wear-resistant material that above-mentioned preparation method obtains.
The relevant technology of the present invention is described further below：
The basis of the technology of the present invention solution is alloying theory, as it was previously stated, secondary alloyed is powder metallurgy side
Method produces the key of iron-based material.First time alloying is to utilize high melt technology first, by designed alloying element, such as
The melting at a high temperature of 1500 DEG C or so such as Cr, Si, Mo, V, C, Fe, after making its complete alloying, it is atomized and is made with high pressure water quick cooling
Take pre-alloyed powder.Contain substantial amounts of carbide and intermetallic compound in this prealloy powder, such as (Fe, Cr)7C3、Mo2C、
The intermetallic compounds such as VC, SiC have (Cr-Mo-Si), (Fe-Mo) and (Cr-Mo) etc..These carbide and intermetallic compound
There are higher fusing point and hardness；It is evenly distributed, and particle diameter is less than 75 μm of powder；It is both to strengthen in ferrous alloy
It is again mutually hard phase, plays a part of to improve intensity and increase hardness；What it was different from being formed under as-cast condition is into continuous thick
Big netted brittlement phase, the carbide hard phase that wetability is poor in alloy is added also different from commercially available.Here it is for the first time
Alloying produces the special benefits of pre-alloyed powder or is innovative point.So-called second of alloying is to sinter pre-alloyed powder to make
Into the alloying process of iron-base products.To ensure that sintered products have high rigidity, high-strength tenacity, it must be added in sintering process
In rise cementation alloy element and rise solution strengthening effect carbide.Therefore, sintered alloy chemical conversion point is devised
And it with the addition of solution strengthening agent.The alloy element of selection has Cu, Ni, Mo, Mn and Fe etc., and Mn is with the shape of MnFe master alloyed powders
Formula adds.The TiC powder for adding commercially available particle diameter to be less than 0.5 μm again in addition, it plays solid solution dispersion-strengtherning, filling coarse grain powder gap
With the effect for preventing crystal grain from growing up；The hardness of sintered alloy body is also improved simultaneously, protects matrix not by plow, matrix protection carbonization
Thing is not peeled off, and improves Wear Resistance.
The secondary alloyed preparation high rigidity high-strength tenacity P/m Iron Base high-abrasive material of the present invention, both make use of smelting skill
Alloying in art, the interfacial effect that has merged the ultra-fine grain powder in modern New Technologies In Powder Metallu Rgy again is theoretical (or to be chi
Very little effect), liquid-phase sintering activity under vacuo is promoted, promotes forming core, prevents crystal grain from growing up, improve consistency, also improve
Intensity and hardness.So as to successfully be manufactured that P/m Iron Base high-abrasive material.Its mechanical and physical performance has reached TM52
The performance of Steel-bonded Cemented Carbide, its performance are as shown in table 1.
1 alloy of the present invention of table compares with TM52 steel bonded carbide performances
| The trade mark | Density (g/ ㎝3) | Sintered state hardness (HRC) | Bending strength (MPa) | Toughness (J/ ㎝2) |
| TM52 alloys | 6.10 | 60~62 | 1900 | 8.1 |
| Alloy of the present invention | 7.54 | 58~61 | 1940 | 9.0~12.0 |
As shown in Table 1, the hardness of alloy of the present invention and obdurability and TM52 steel bonded carbide are substantially suitable.This is melting
What casting method was difficult to.As it was previously stated, just without hardness number in the standard of " Hadfield steel casting ", in " wear-resistant white
In the standard of ironcasting ", the hardness highest trade mark also only has HRC58.As can be seen here, the present invention is realized using powder metallurgy process
High rigidity, high-strength tenacity, undoubtedly there is a prominent meaning to improving wearability.
The composition of the present invention, as it was previously stated, first time alloying is to produce pre-alloyed powder.It is theoretical according to alloying, if
The constituent element for counting pre-alloyed powder is largely carbide, while to have enough carbon, just can guarantee that carbide shape
Into needs.On the other hand, the content of design ingredient percent is:Cr 18%~23%, Mo 0.8%~1.8%, Ni
0.6%~%1.5%, Ti 0.3%~0.8%, Si 0.4%~1.0%, V 0.6%~1.2%, C 2.4%~2.9%,
Fe is surplus.Any commercially available carbide hard phase can not be added in the producing process of pre-alloyed powder, existed completely by alloying element
Alloying carbide and intermetallic compound are formed during high melt, just can guarantee that its enough hardness and obdurability.This
The gross mass degree for inventing the pre-alloyed powder is 90%~93%.Double sintering alloying of the present invention rises viscous
The alloying ingredients of knot effect and the carbide gross mass degree for playing solution strengthening are 10%~7%.Rise as previously described
The alloy element of double sintering effect and play the mass percentage content of carbide formers of solution strengthening and be：Cu 12%~
24%th, Ni 12%~20%, Mo 9%~15%, Mn 6%~12%, TiC15%~25%, Fe are surplus.Wherein TiC grains
Footpath is less than 0.5 μm, and Mn is added with MnFe master alloyed powders.It can be seen that by the composition of above-mentioned design and do not add carbon, be because addition
Carbide former is few, but must contain a small amount of carbon, and the source of carbon is in MnFe intermediate alloys and TiC particles, containing few
The free carbon of amount.A part for these free carbons,, can be with gold when temperature reaches 1100 DEG C or so during vacuum-sintering
Belong to the O in powder2React, form the discharge of CO gases, reducing metal.Also small part forms carbide with some metals
(M2C).If the metal that separately adding carbon can make to be solid-solution in matrix is reduced, alloy is caused to become fragile, so can not separately add carbon.In addition,
As it was previously stated, playing the ultra-fine grain TiC that solid solution dispersion-strengtherning is made, also need strictly to control its amount, otherwise can also alloy is become fragile.
The production technology of the present invention, it is substantially identical with steel bonded carbide, but also have some differences.Something in common is：Together
Sample uses powder metallurgy conventional production process, i.e. ball mill mixing, add-on type agent and is pelletized in compound, is then pressed into hair
Base, blank continue heating sintering and obtain product after forming agent is sloughed in pre-burning in a vacuum furnace.But difference mainly has at 3 points：
First, steel bonded carbide divides hard phase and Binder Phase；And sheerly powder metallurgical ferrous alloy of the invention.But the present invention needs molten
Powder by atomization process is refined to produce pre-alloyed powder.Certainly it can also be produced with elemental metals powder completely, but its alloy
Change will not be complete, because it only relies on elements diffusion in sintering process and migration to form alloying be limited.Certain
A little powders may be soldering, without real complete alloying.So the hardness of product can be very low, also uneven, intensity, tough
Property is also difficult to reach requirement.Second, the ball mill mixing that the present invention uses for dry type ball mill mixing, is not required to as steel bonded carbide will
With protective substance come ball mill mixing, the more aobvious simplification of technique.Third, product of the present invention is during dry type ball mill mixing, can
Forming agent zinc stearate is added simultaneously, after mixing, then the compacting of row blank.It is this hard because the suppression performance of iron based compacts is poor
Resin acid zinc forming agent needs higher pressing pressure, is typically greater than 600MPa pressing pressure, if the big pressure of product size
It is higher.So it is unfavorable for making forming agent with zinc stearate.After the present invention uses dry type ball mill mixing, add rubber solutions forming agent,
Blank compacting is carried out by granulation again, shaping press power can be greatly decreased, so as to reduce grinding tool damage and abrasion, extends its longevity
Life, is also beneficial to product density.The actual density of this product is 7.6~7.7g/cm3, and the density (being shown in Table 1) of sintered products
For 7.54g/cm3, relative density reached 97.9%~99%.
Product of the present invention is in addition to mechanical and physical performance is suitable with TM52 steel bonded carbide, its contrast abrasion performance abrasion
Performance test is better than TM52.Simultaneously also with prealloy powder and only with the sintered sample produced of a certain amount of copper powder (i.e. without two
The sample of secondary alloying), sample isSintered state pole, be put into small-sized ball milling bucket, add bearing
Alloy steel ball 6kg, dry type wear hardness experiment is carried out, in mechanical milling process, ball milling bucket outer wall feel has obvious fever phenomenon.Through
After 31h abrasions, taking-up is weighed, as a result as shown in table 2.
Table 2 wears away wear test result
Found out by table 2, the wearability of secondary alloyed rod improves about 1.3 times than TM52.With without secondary alloyed burning
Tie rod and improve about 0.8 times.This phenomenon is explained, can only go to explain in terms of alloying principle.As it was previously stated, the present invention first
In the alloying component of secondary pre-alloying powder, carbon content is high, and the alloying element of formation carbide and intermetallic compound is more, high temperature
Alloying is complete during melting.Hard Inclusion is more and evenly distributed.Although TM52 is liquid-phase sintering, but it never as rolling molten steel
Such alloying is more complete, besides TM52 Hard Inclusion is also one of reason less.Next to that designed during double sintering alloying
Alloying element and content and sintering process parameter selection it is reasonable.For example, design sintered alloy temperature at 1100 DEG C,
The length of sintering time and soaking time is particularly significant.It is powder deoxidation again because being now the process that copper powder forms micro- molten bath
Process, the time that have abundance allows micro- molten bath to spread, the diffusion in micro- molten bath, promotes the grain boundary between powder, live
Property sintering process.When temperature reaches more than 1200 DEG C, the alloying into liquid phase sinters, sintering velocity and soaking time also phase
When important.MnFe powder when therefore is in semi-molten state, allows it to return slow diffusion, reactive sintering is reached peak, makes Ni, Mo more
The good dystectic TiC particles of wetting, further promote grain boundary, improve bond strength and preferably filling gap.It is real
Existing product of the present invention has the highly alloyed best illustration of high density, high rigidity, high-strength tenacity and high-wear resistance.
, can be to secondary alloyed preparation high rigidity high-strength tenacity powder metallurgy iron by above-mentioned technique and foregoing composition design
The characteristics of base high-abrasive material, which advises, to be received following (beneficial effect)：
1. by the as shown by data of foregoing table 1, ferrio wear-resistant material physical and mechanical property of the invention is excellent, has reached work
The technical standard of the corresponding trade mark of industry steel bonded carbide.
2. saving hard phase resource, product addition TiC of the present invention amount is few, forms carbide by alloyage process completely
Impact and abrasion are resisted with intermetallic compound, unlike steel bonded carbide is completely dependent on hard phase to resist abrasion, not only
Cost high-wearing feature is also poor.
3. being found out by the abrasion test of foregoing table 2, the present invention is resistant to the high-wearing feature material of Contact -impact fretting wear
Material.
