Description
The present invention relates to a kind of improved silicon nitride (Si
3N
4) base ceramic material, particularly a kind of ceramic material that is formed by silicon nitride matrix, wear-resisting decentralized photo and resistant to elevated temperatures Grain-Boundary Phase that is suitable for as cutter.
Silicon nitride is made the principal crystalline phase matrix in recent years, and titanium carbide (TiC) is made the cutter that wear-resisting disperse phase is made, and has good cutting effect, and this is because silicon nitride and titanium carbide all have good wearability.But the crystal boundary phase of this class cutter material usually was the relatively poor glassy phase of high-temperature behavior in the past, under cutting temperature because the softening cutting ability that will have influence on cutter of crystal boundary glassy phase.United States Patent (USP) U.S.128070(EP 0035777), adopt silicon nitride to make matrix, titanium carbide is made the anti-decentralized photo of mill, yittrium oxide (Y
2O
3) etc. as densified auxiliary agent.In fact, by the impurity in densified auxiliary agent and the material such as SiO
2Often be glassy phase etc. formed crystal boundary, thereby affect wearability and the working durability of cutter.This patent is mentioned and is added Al
2O
3As additional additive problem, but And tests.
Because in working angles, the point of a knife portion temperature is very high, can reach more than 1000 ℃.Therefore the bad thermotolerance of crystal boundary glassy phase will have a strong impact on the performance of the intrinsic wear resisting property of silicon nitride principal crystalline phase, thereby influence the cutting ability and the working durability of cutter.
Task of the present invention is kept Si exactly
3N
4As decentralized photo, by changing densified auxiliary agent and suitable technology, improve Si as principal crystalline phase matrix and wear-resisting TiC
3N
4The structure of Grain-Boundary Phase, thus its hear resistance and elevated temperature strength improved, increase the wearability of point of a knife part under cutting high temperature.
Task of the present invention is finished with following two aspects: remove a small amount of Y in batching
2O
3Or other rare earth oxides, also add Al
2O
3Or MgAl
2O
4, MgO, ZrO
2Outside oxide, in order to stop crystal grain too to develop and to promote densified effect, also can add a small amount of AlN; In order to reduce as far as possible the glassy phase of crystal boundary, improve the hear resistance of Grain-Boundary Phase, can carry out annealing in process to material, make crystal boundary form the higher crystalline phase of a part of fusing point.Such as yttrium-aluminium-garnet, aluminium oxynitride silicon solid solution, because the addition of densified auxiliary agent is very little, so principal crystalline phase still is β-Si
3N
4By above-mentioned measure, can obtain at last the ceramic cutting tool material of high compactness wearability high tenacity.
Detailed description of the present invention is as follows: according to the present invention, at the α-Si of 100 parts of weight
3N
4In the powder, 5～30 parts in the wear-resisting decentralized photo TiC powder of outer adding, densified auxiliary agent Y
2O
3Or 1～10 part of other rare earth oxide, Al
2O
3Or other oxidation compound such as MgAl
2O
4, ZrO
2, MgO etc., 0.5～5 part, AlN0.5～5 part.
Raw-material technical requirements be can be: Si
3N
4α is greater than 90% in the powder, purity＞95%, and median size is in 0.1～2.0 μ scope; The purity of TiC＞98%, median size is in 0.1～3 μ scope; The purity of densification auxiliary agent is greater than 98%, and median size is the scope of 0.1～3 μ.
According to the present invention, this attrition resistant ceramice kuife material based on nitrided silicon can adopt pressureless sintering, and hot pressing or hot isotatic pressing method reach densification.The temperature range of pressureless sintering can be 1600～1900 ℃, and hot pressed temperature range can be 1600～1850 ℃ of pressure and can be 150～400kg/cm
2, constant temperature time can be 15～90 minutes.As adopting pressure sintering, technical process is as follows: with α-Si
3N
4, the powder such as TiC, densified auxiliary agent is in suitable ratio weighing, carries out mix grinding, oven dry, granulation, in the graphite jig of then mixed-powder being packed into, places the pressing technology that heats up in the hot pressing furnace, the β-Si that obtains
3N
4Be the material of base, carry out annealing in process again, annealing temperature can in 1200～1500 ℃ of scopes, cut into blade and use at last.
With the high-wearing feature silicon nitride ceramic material that technology of the present invention makes, its principal crystalline phase should be β-Si
3N
4, decentralized photo is TiC, its Grain-Boundary Phase should be crystalline phase and indivisible glassy phase.
The prepared high-wearing feature silicon nitride ceramic material according to the present invention, can be used to process difficult-to-machine materials such as quenched steel, cold hard cast-iron, not only can make cutter, also can be used to make multiple components of machine such as precision bearing, axle sleeve, gauge block, guide rail, nozzle and wire-drawing die.
Embodiment is averaged 1.7 microns of particle diameters, the α-Si of purity more than 95%

4Powder 100 grams add 30 gram TiC, 4 gram Y
2O
3, 3 gram Al
2O
3, 2 gram AlN, mix grinding is 48 hours in ball grinder, dries then granulation, puts into graphite mo(u)ld, and adopting pressure is 200 kg/cm, and temperature is 1700 ℃～1850 ℃, and the time is to carry out hot pressing in 30 minutes, just obtains dense sintered body.Again test specimen is carried out anneal under 1300 ℃～1500 ℃.Resulting material, its bending strength are 70～80 kilograms/mm sq, hardness HRA93～93.5, toughness a
k=6～7 kilograms-centimetre/square centimeters, relative density 99.5～100%.
Then and do not add AlN or add behind the AlN and unannealed sample carries out cutting test relatively.Workpiece to be machined is CrWMn quenched steel (HRC58～62), cutting speed V=57.93 rice/minute, amount of feed f=0.1 millimeter/commentaries on classics, depth of cut a=0.25 millimeter when the total distance of cutting is decided to be L=1373 rice, is measured the wear of the tool flank V of three kinds of cutters respectively
B, it the results are shown in following table.
Can see that from table the AlN additive anneals again simultaneously for adding, the knife face attrition value can reduce about 30% thereafter.
When the wear of the tool flank value is fixed as V
BIn the time of=0.3 millimeter, the total distance L(of the cutting of various cutters or cutting time T) can be used as the comparison in Tool in Cutting life-span.When cutting CrWMn hardened steel (HRC 58～62), the working durability of cutter of the present invention is compound alumina ceramic cutter (Al for 2 times of composite silicon nitride cutter in the past
2O
3+ TiC) 7 times are 113 times of hard alloy cutter (YT14).
When cutting hardness was the cold hard cast-iron of HS71-73, workpiece size was 256 * 450 millimeters of φ, lathe CW6163, and cutting data: f=0.19 millimeter/commentaries on classics, the a=0.25 millimeter, various cutters adopt the optimum cutting speed of self.Result of the test shows: the working durability of cutter of the present invention is compound alumina ceramic cutter (Al for 2.1 times of in the past composite silicon nitride cutter
2O
3+ TiC) 6 times are 24 times of Sweden ultrafine gain size cutter H1.
