Definitions
- the present invention relates to a Fe-Co alloy more particularly intended for the manufacture of electromagnetic actuator with high dynamics, without being limited thereto.
- An electromagnetic actuator is an electromagnetic device that converts electrical energy into mechanical energy with an electromagnetic conversion mode. Some of these actuators are called linear because they convert the received electrical energy into a rectilinear movement of a moving part. Such actuators are found in solenoid valves and electro-injectors.
- a preferred application of such electro-injectors is the direct injection of fuel into combustion engines, especially diesel engines.
- Another preferred application relates to a particular type of solenoid valve used for the electromagnetic control of the valves of internal combustion engines
- the electrical energy is supplied in a winding by a series of current pulses, creating a magnetic field that magnetizes a non-closed magnetic yoke, thus having a gap.
- the geometric characteristics of the cylinder head make it possible to direct most of the magnetic field lines axially vis-à-vis the gap zone. Under, the effect of the electric pulse, the air gap is subject to a magnetic potential difference.
- the actuator also comprises a core made mobile by the action of the electric current in the coil. Indeed, the magnetic potential difference introduced into the coil between the movable core resting on one of the poles of the cylinder head and the opposite pole of the cylinder head creates an electromagnetic force on the magnetized core, via a magnetic field gradient.
- the magnetized core is set in motion!
- the rest position can also be located in the middle of the air gap, thanks to two symmetrical springs, promoting by their stiffness the dynamics of the moving part, in particular for electromagnetically controlled valves.
- the setting in motion of the mobile core occurs with a phase shift with respect to the moment of generation of the electrical pulses.
- the metal has an electrical resistivity at 20 0 C p e ⁇ high and in particular greater than 50 ⁇ .cm and a coercive force Hc low, c ' ie less than 32 Oe and preferably less than 8 Oe.
- the core has a saturation magnetization Js high, ie greater than 1.75 T and preferably greater than 1.9 T, so as to allow a maximum force at the end of this high pulse as possible. It is indeed this force which guarantees the maintenance of the open or closed position of the actuator, which is particularly important when it is necessary to totally interrupt the flow of a fluid at high pressure or to compensate the return force of one or more springs.
- Such saturation magnetization level thus provides a compact actuator having a high strength and power density.
- These magnetic cores have various shapes that can be made from wires, bars, plates or rolled sheets. They must therefore have good heat-formability, and preferably good cold-forming ability when necessary.
- these cores can be subjected to a slightly oxidizing working environment and must therefore have a good resistance to corrosion to resist this type of premature wear.
- tensile strength Rm greater than 500 MPa and preferably, an elastic limit R 0 , 2 greater than 250 MPa in the hot-rolled state at a thickness of at least 2 mm.
- Ferrocell (Fe-Co) alloys such as those described in EP 715,320 are generally used for the manufacture of electromagnetic actuators. described have 6 to 30% cobalt, 3 to 8% of one or more elements selected from chromium, molybdenum, vanadium and / or tungsten, the balance being iron. These alloys, however, have insufficient dynamics.
- the present invention aims to provide a material suitable for the manufacture, economically, of cores for compact electromagnetic actuators with high dynamics and high saturation. This material must also allow implementation hot, and preferably, cold, improved.
- a first object of the invention thus consists of a Fe-Co alloy whose composition comprises in% by weight:
- the alloy may further comprise the following additional features:
- the Fe-Co alloy is such that: ⁇ 10 Co +% Ni ⁇ 22 - the Fe-Co alloy is such that: 1 ⁇ Cr ⁇ 5.5
- the Fe-Co alloy is such that: Ni ⁇ 1
- the Fe-Co alloy is such that: Al ⁇ 2
- the alloy according to the invention has a composition in% by weight which comprises:
- the alloy according to the invention can be formed into a bar, wire, plate or rolled sheet. It can in particular be used for the manufacture of electromagnetic actuator movable core manufactured from a bar or a wire or a plate or a rolled sheet.
- Such an electromagnetic actuator comprising a movable core of Fe-Co alloy according to the invention can in particular be used in an injector for an electronically controlled combustion engine or even as an internal combustion engine valve actuator. electronic control.
- the alloy according to the invention is an iron-cobalt alloy with a low cobalt content having moderate levels of addition elements.
- the cobalt content is between 6 and 22% by weight in order to obtain a good saturation magnetization while maintaining a high resistivity. It is less than 22% by weight to reduce the amount of expensive additive elements while maintaining good saturation.
- the nickel content which may partially substitute cobalt, is, however, maintained at less than 4% because its presence considerably increases the coercive field of the alloy.
- the silicon content of the alloy according to the invention is greater than or equal to 0.2% by weight. Such a minimum content makes it possible to obtain a good mechanical resistance Rm. Moreover, this element makes it possible to very effectively increase the coercive field of the alloy by lowering it significantly. However, the joint addition of aluminum and 6% silicon is limited to preserve the alloy good heat-transformability. It is furthermore preferred to limit this cumulative content to less than 4% by weight in order to keep the alloy good cold processability.
- the aluminum content of the alloy according to the invention is less than or equal to 4% by weight.
- This element has a role similar to that of silicon by favoring the obtaining of a weak coercive field. We limit its addition to 4% because otherwise Js would become too weak. However, it does not improve the mechanical properties of the alloy.
- the chromium content of the alloy according to the invention is between 0.5 and 8% by weight. This essential element of the alloy makes it possible to extend the range of addition of silicon, with respect to the transformation with hot and cold, while maintaining the good properties of resistivity and saturation. However, it is limited because it increases the coercive force of the alloy.
- the manganese content of the alloy according to the invention is less than or equal to 0.90% by weight. This element is added at a rate of at least 0.10% by weight to improve the heat-transformability of the alloy. Its content is limited because it is a gamma element and the appearance of the ⁇ phase greatly degrades the magnetic performances.
- the titanium content of the alloy according to the invention is less than or equal to 1% by weight and preferably less than 0.1%, because this element easily forms nitrides, either during production or during annealing. under air or under ammonia, nitrides which strongly degrade the magnetic properties and are therefore harmful.
- the molybdenum content of the alloy according to the invention is less than or equal to 3% by weight. This element can be added to improve the electrical resistivity of the alloy, in complement or partial substitution of chromium.
- the carbon content of the alloy according to the invention is less than or equal to 1% by weight, and preferably less than or equal to 0.1% by weight.
- the presence of carbon deteriorates the magnetic properties of the alloy and so the content is reduced to avoid such degradation.
- the cumulative vanadium and tungsten content of the alloy according to the invention is less than or equal to 3% by weight. These elements can be added to improve the electrical resistivity of the alloy, in complement or partial substitution of chromium.
- the cumulative content of niobium and tantalum of the alloy according to the invention is less than or equal to 1% by weight. These elements can be added to improve the ductility of the alloy and thus limit its fragility.
- the cumulative content of oxygen, nitrogen, sulfur, phosphorus and boron is limited to 0.1% by weight, since these elements are oxidants and tend to form precipitates which are very unfavorable to the magnetic properties and to the mechanical ductility of the material.
- Such a limitation supposes, in particular, that the alloy according to the invention is manufactured from raw materials of good purity.
- the alloy according to the invention must also respect a number of relationships between some of these elements. Thus the following four equations must be respected:
- Relation (3) represents a saturation criterion which makes it possible to ensure that the alloy according to the invention will have saturation magnetization Js of less than 2.2T in a manner consistent with the additions of non-magnetic elements necessary for the need of high dynamics. magnetization.
- Relation (4) in combination with relation (2), makes it possible to guarantee a high electrical resistivity p e ⁇ , and in particular greater than 50 ⁇ .cm.
- the manufacture of the alloy according to the invention can be done conventionally for this type of alloy.
- the various elements constituting the alloy can be melted by induction under vacuum, then cast into ingots, billets or slabs. These are then hot-forged at temperatures ranging from 1000 to 1200 ° C. and then hot-rolled after reheating to a temperature greater than or equal to 1150 ° C., the end-of-rolling temperature being between 800 and 1050 ° C.
- the plates, bars or hot-rolled strips thus produced can be used as is or cold-rolled after pickling by dipping in one or more acid trays and annealing.
- Such elements may for example be aluminum, silicon or chromium.
- the raw materials necessary for producing the alloy were melted by vacuum induction and vacuum cast in a 50 kg ingot.
- the ingots are then hot-forged at between 1000 and 1200 ° C. and then hot-rolled from heating to
- the strips are either characterized in the hot rolled state by machining. tensile test specimen, washers for magnetic characterization, elongate samples for measuring electrical resistivity, or characterized after cold rolling to the thickness of
- the breaking strength Rm is measured on a tensile test piece after annealing the hot rolled at 900 ° C. for 4 hours under H 2.
- the corrosion resistance Tcor is evaluated on a hot rolled rough surface, ground to obtain a clean surface with a very low roughness, and then left at 20 ° C. in a salt spray atmosphere.
- the test for suitability for hot or cold processing was carried out by simple observation of non-weakened banks during the rolling operations (hot, cold) of the test ingots.
- compositions of the test castings are shown in Table 1 below, it being understood that the cumulative contents of all the oxygen, nitrogen, sulfur, phosphorus and boron tests are less than 0.1% by weight and that the rest compositions consists of iron. Table 1
- the alloy according to the invention makes it possible to combine a set of properties that were not accessible to the prior art:
- a high electrical resistivity at 20 ° C. typically> 50 ⁇ .cm, while maintaining saturation magnetization at 20 ° C., high to very high, typically> 1, 75T and preferably> 1, 9T, and can not exceed 2.2T because of the additions necessary for the great magnetization dynamics of the alloy.
- a preferred application of the alloys according to the invention is the manufacture of cores for electromagnetic actuators, whether linear or rotary.
- Such compact, dynamic and robust actuators can advantageously be used in injectors of direct injection combustion engines, in particular for diesel engines, and in moving parts of actuators controlling the movement of the valves of internal combustion engines.
