Definitions
- the subject of the invention is cermets based on borides of transition metals, in particular titanium diboride, having in particular improved toughness.
- Cermets are hard materials used in particular to make cutting or drilling tools and wearing parts. They generally consist, as their name suggests, of a predominantly hard but fragile ceramic phase and a much less hard but tenacious metallic binder phase, which gives them an interesting and rare combination of hardness and tenacity.
- ceramic is taken here in the broad sense, including in particular the oxides, nitrides, carbides and borides of the transition metals, or even their combinations.
- the inventors have observed these facts experimentally, for example on TiB2-Fe cermets.
- To prepare these cermets they mixed titanium diboride powder TiB2 (average grain diameter: 1 to a few ⁇ m) with iron powder (average grain diameter 1 to a few ⁇ m) by conventional means (mixer, ball mill, attrition mill, etc.). The mixture was then compressed under 100 to 200 MPa of pressure. The sintering was carried out for 1 to 4 hours, at a temperature between 1450 and 1550 ° C., depending on the volume iron content of the cermet (10 to 20% by volume).
- the object of the present invention is to find conditions making it possible to manufacture cermets based on transition metal borides which do not have the drawbacks of cermets of the same type obtained according to the prior art and allowing their use in the envisaged applications, in particular due to their high tenacity.
- Patent application DE-A-28 46 889 relates to an alloy powder, its preparation and its use for manufacturing sintered parts.
- the alloy powder consists essentially of a boride or a complex boride phase as a support for hardness and a metal or an alloy as a binding phase.
- the iron boride is partially replaced by at least one boride of another metal such as for example a transition metal (see, for example, page 5, lines 16 to 24).
- the borides used in Example 3 contain 70.32% by weight of iron for the boride of structure MB which is used in an amount of 43% by weight to form the sintered product, and 76.77% by weight of iron for the boride of structure M2B which is used at a rate of 16% by weight to form the sintered product.
- Comparable proportions of iron-based borides are used in the other examples.
- the sintered products disclosed in patent application DE-A-28 46 889 therefore all contain a high proportion of iron boride.
- the object of the present invention is to avoid the presence of metal boride of the binder phase (iron in particular).
- patent application DE-A-28 46 889 teaches that the presence of aluminum as an impurity in the alloy powder plays an unfavorable role, which should have dissuaded the person skilled in the art from adding this item.
- Patent application FR-A-2 514 788 teaches a sintered hard alloy very similar to that taught by document DE-A-28 46 889, in which the hard phase composed of "multiple borides” contains at least 10% by weight of iron, which goes against the object pursued according to the present invention.
- the inventors have found that the interaction between the hard transition metal boride and the metal binder which causes a drop in toughness, can be prevented or at least greatly reduced by adding certain elements to the binder.
- metal type in the form of simple or compound bodies, during the preparation of the mixture of the boride and the metal binder, that is to say before the sintering of this mixture.
- the elements in question are essentially the transition metal entering into the composition of the transition metal boride constituting the hard phase, mainly present in this boride and a metal X chosen from aluminum, alkaline earth metals, Sc, Y, lanthanides, actinides and alloys consisting of iron and ceric metals, or a mixture of at least two of these metals X.
- the added transition metal is transformed into oxide in which part of the oxygen can be replaced by nitrogen and / or carbon and the metal X is transformed into oxide.
- oxides precipitate in the form of dispersions of separate oxide particles, or combined in the form of complex oxides.
- the carbon possibly present in the oxide of the transition metal is due to the presence of this element, as an impurity, in the boride of the hard phase.
- the ratios x / y and x '/ y', identical or different, are equal to 1/2 or 2/5, or close to these values.
- the alkaline earth metals X preferably used according to the invention are Mg and Ca.
- the other metals X preferably used according to the invention are Ce, Pr, Nd, Gd, Dy, Th, U as well as an alloy, consisting of iron and ceric metals, such as for example that known under the name of Mischmetall ®.
- the cermet according to the invention comprises between 20 and 99%, preferably between 50 and 97% by weight of hard phase 1).
- the transition metal T or T '(added according to the invention) can be added in elementary form, that is to say not combined with the mixture of the other powders.
- it is advantageously used in the form of its THz type hydride, z being an integer or decimal, or one of its alloys of type (T, L), L being l '' one of the binding metals used according to the invention, namely Fe, Ni, Co or Cr, or one of its mixed hydrides of type (T, L) Hz, z being an integer or decimal number, because these compounds or alloys are generally more easily grindable than pure metal.
- the metal X can also be added in elementary form, that is to say not combined, to the mixture of the other powders.
- it is advantageously used in the form an alloy XaLb or XcTd, and / or a corresponding mixed hydride (X, L) Hz or (X, T) Hz ', and / or a mixed boride XaLbBt (L being preferably Fe, Ni or Co) because these alloys, hydrides or borides are generally more easily grindable and less reactive with respect to the environment than pure metal X.
- a, b, c, d, t, z and z ' are numbers whole or decimal.
- Mixing with grinding can be carried out according to any process known to those skilled in the art. It is advantageously carried out by attrition in a ball mill.
- the duration of the grinding is preferably from 2 to 48 hours.
- the compression is advantageously carried out under a pressure of 50 to 300 MPa.
- the sintering is advantageously carried out at a temperature of 1300 to 1700 ° C, for 1 to 3 hours, under pressure of 1 to 104 Pa of argon, or under pressure of 105 Pa of hydrogen, or under vacuum of 10 ⁇ 2 to 10 Pa, or by hot isostastic compression under 100 to 200 MPa of argon (HIP press: ASEA Q1H-6 for example).
- HIP press ASEA Q1H-6 for example.
- the cermets obtained according to the invention can be used in particular for manufacturing cutting tools, drilling tools or Wear parts.
- Example 1 can be considered typical of the prior art, in order to concretize the improvements linked to the invention, the inventors have carried out Example 2 which follows.
- Example 1 The grinding is carried out as in Example 1, with the only difference that the grinding time is reduced to 2 hours.
- the compression and dewaxing are carried out as in Example 1.
- the sintering is carried out at 1500 ° C., under pressure of 103Pa of argon, for one hour.
- the total porosity measured on the sintered test pieces is 2%.
- the binder consists essentially of an iron-nickel alloy.
- neodymium oxide particles Nd303
- titanium oxycarbonitride particles Ti
- Example 3 (according to the invention):
- the ground mixture is separated from the beads by sieving.
- test pieces (5 g per test piece) is carried out at 70 MPa, the matrix (in hardened steel) being lubricated with zinc stearate.
- test pieces are encapsulated and sintered by hot isostatic compression (HIP ASEA Q1H-6 press) according to the following cycle: TEMPERATURE (° C) PRESSURE (Argon MPa) BEGINNING END SPEED ° C / min BEGINNING END SPEED MPa / min Min duration 20 430 10 empty* empty* - 43 450 450 - empty* empty* - 30 450 820 10 empty* empty* - 37 820 820 - empty* 0.5 - 0.017 820 1000 10 0.5 0.5 - 18 1000 1350 8.75 0.5 150 3.75 40 1350 1350 - 150 150 - 30 1350 300 - 35 150 70 - 2.7 30 300 270 - 15 70 1 - 35 2 * empty: 1 Pa
- the binder phase is essentially iron: there does not appear any boride phase Fe2B or FeB, while this phase is predominant in the FN, FNMo and FNW alloys developed according to the prior art.
- This absence of iron boride phase in the alloys according to the invention is confirmed by the increase in ductility of the binder phase, quantified by the measurement of the stress intensity factor K IC by the PALMQVIST indentation method.
- the alloys according to the invention exhibit a fine dispersion of alumina particles (Al2O3).
- the mixture of powders is produced in a ball mill (of stainless steel) under the conditions described in Example 3.
- the crude mixture is separated from the beads by sieving.
- test pieces are done under 100 MPa, in a hardened steel matrix, lubricated with zinc stearate.
- test pieces are encapsulated and sintered by hot isostatic compression (HIP ASEA Q1H-6 press), according to the cycle described in Example 3.
- the alloys according to the invention exhibit, in addition to the hard phase TiB2 and the binder Fe / Ni / Cr or stainless steel 316L, a fine dispersion of alumina and oxycarbonitride particles of titanium.
- the hardness decreases only by 3% while the toughness increases by around 40%.
- Example 5 (according to the invention):
- Example 2 The grinding is carried out as in Example 2.
- the compression and the dewaxing are carried out as in Example 1.
- the sintering is carried out at 1600 ° C. under argon pressure of 103Pa, for two hours.
- the total porosity measured on the sintered test pieces is less than 0.5%.
- the hard phase consists of the solid solution (Ti, Cr) B2 and the binder is essentially an Fe / Ni alloy. Note the presence of a fine dispersion of particles of neodymium oxide (Nd2O3) and titanium oxycarbonitride [Ti (O, C, N)].
- VICKERS hardness under load of 30 kg (294 N) of the sintered test pieces is 14,900 ⁇ 500 MPa, i.e. 6% higher than that of the test pieces of Example 2 (without substitution of TiB2 by CrB2) which is 14000 ⁇ 500 MPa.
