Definitions
- the invention relates to the field of brazing sheets for tubes or plates of heat exchangers made of aluminum alloys, in particular those used for cooling or optimizing the efficiency of the engines, heating or air conditioning of the passenger compartment, but also for any other heat exchange function, in motor vehicles.
- plates for exchanger tubes or plates subjected to a severe corrosive environment such as tubes or plates for charge air coolers undergoing exhaust gas recirculation or air conditioning evaporator plates.
- Aluminum alloys are now mainly used in the manufacture of heat exchangers for the automobile because of their low density, which allows a weight gain, especially compared to copper alloys, while ensuring good thermal conduction, ease of implementation and a good resistance to corrosion.
- the exchangers comprise tubes or plates for the circulation of the internal fluid and fins or spacers, and possibly a disrupter, to increase the heat transfer between the internal fluid and the external fluid, and their manufacture is done by mechanical assembly, by soldering.
- the core sheet constituting the tube or the plate generally aluminum alloy of the AA3xxx series
- a so-called brazing alloy generally of the AA4xxx series. This has the advantage of melting at a temperature below the melting temperature of the core and, by applying a thermal brazing cycle, to be able to create a connection between two materials to be assembled, that is to say soldering, the alternative being welding.
- FIG. 1 the core of the tube strip bearing reference numeral 2, and its internal and external brazing alloy plating, reference numeral 1.
- the spacers which are positioned between the different rows of tubes, consist of an alloy of the AA3xxx series not plated.
- the disrupters which are inserted in the tubes, are also alloy AA3xxx series and not plated.
- the brazing of the spacers on the tubes is provided by the AA4xxx plating of the outer face of the tube.
- Brazing of the disrupters in the tubes is provided by the 4xxx plating of the inner face of the tube. Alloys AA3xxx used for interleaves and disrupters may be identical or not.
- the alloy of the AA3xxx series used for the core of the tube is most often made of "long-life" alloy, that is to say with good resistance to external corrosion, saline.
- FIG. 2 A diagram of such a disruptive tube is shown in Figure 2, the tube bearing the mark 1, the disruptor mark 3 and the solder alloy veneers mark 2.
- An example is described in EP 0283937 Al from Nihon Radiator Co. Ltd.
- charge air coolers as well as plate air conditioning circuit evaporators which therefore have fins or spacers on each side and also require the presence of a AA4xxx series solder alloy layer on each side. 'they.
- the exhaust gases which can condense, can generate in the cooler a particularly severe corrosive medium, characterized in particular by a low pH (which can be significantly less than 3) ⁇
- Plate evaporators of air conditioners also undergo a corrosive attack, under less severe conditions, related to particularly saline projections of the road environment.
- Such a configuration is shown diagrammatically in FIG. 3, the core of the tube bearing the reference numeral 3, the outer alloy coating of the AA4xxx series referenced 4, the inner lining also made of alloy of the AA4xxx series, the reference numeral 1 and the intermediate coating.
- the alloys used for the intermediate layer having a low flow stress at high temperature, the hot rolling of a multilayer composite including them is particularly difficult. Industrial tests carried out on twelve coils by the plaintiff revealed a very difficult or even impossible coiling.
- a known solution for facilitating rolling is to increase the hot flow stress of the intermediate plating, in particular by the addition of hardening elements. This is the case of titanium at levels up to 0.3% as mentioned in the application WO2009 / 128766A1 of "Sapa Heat Transfer AB”. Manganese is also cited as hardening by solid solution.
- the AA3003 type alloy is also conventionally used in heat exchangers because it has a very good compromise between mechanical resistance, corrosion and formability. However, its high iron content (up to 0.7%) makes it more susceptible to corrosion than an AA1050 type alloy for example. In addition, the presence of copper up to 0.2% makes it less sacrificial and more sensitive to corrosion in general and intergranular in particular.
- the aim of the invention is to optimize the choice of the composite material or multilayer brazing sheet made of aluminum alloy, and in particular of the core and intermediate plating, intended for the production of exchangers, to improve their behavior in a severe corrosive environment such as that created by the recirculation of motor vehicle exhaust gases, and to a lesser extent air-conditioning evaporators, with no surplus of material used nor space or significant weight and allowing manufacturing conditions to from the brazing sheets at least equivalent, from the point of view of ease of implementation and cost, the solutions of the prior art.
- the subject of the invention is a brazing sheet consisting of an aluminum alloy core sheet of the AA3xxx series, coated on at least one face with a first so-called intermediate aluminum alloy cladding layer comprising, in percent by weight, 0.35 to 1.8% manganese, other elements less than 0.3% each and 1% in total, remains aluminum, itself coated with a second layer of alloy plating of the series AA4xxx, in which the alloy of the core sheet is selected, and the core sheet prepared, so as to have a substantially recrystallized structure after soldering.
- essentially recrystallized structure is meant a structure whose proportion of recrystallized grains is at least 90% and preferably 100%.
- the presence of anti-recrystallizing elements of the Cr, V, Zr and Se type is controlled and limited and the plate for the manufacture of the core sheet undergoes after casting and peeling, and before bonding, homogenization at a temperature of 550 to 630 ° C for at least one hour.
- composition of the intermediate layer is the following (% by weight):
- the Mn content of the intermediate layer is between 0.35 and 1.7%, more preferably 0.35 and 1.4%.
- composition of the intermediate layer is the following (% by weight):
- the Mn content of the intermediate layer is advantageously between 0.5 and 0.9% and better still between 0.6 and 0.8%.
- the face of the core sheet opposite the face coated with said first so-called intermediate plating layer may be coated with an AA4xxx series alloy plating layer or other intermediate plating layer of the same type.
- composition as the first, itself coated with an alloy plating layer of the AA4xxx series is coated with the alloy veneer plates, intermediate and external of the AA4xxx type, each have a thickness of 5 to 10% of the total thickness of the brazing sheet.
- a brazing sheet made according to the above requirements has, after brazing, a life without perforation of the core sheet to the SWAAT test, according to ASTM G85-A3, of more than 8 weeks.
- brazing sheets may advantageously be used for the manufacture of a heat exchanger of a motor vehicle, in particular a heat exchanger of the "Charge air cooler” or RAS type, also known as “Charge air cooler “or CAC, or an exchanger type” Evaporator "in air conditioning circuits.
- a heat exchanger of the "Charge air cooler” or RAS type also known as “Charge air cooler “or CAC, or an exchanger type” Evaporator "in air conditioning circuits.
- the invention also relates to a heat exchanger of the type “charge air cooler” or RAS, also known as “Charge air cooler” or CAC, or a heat exchanger of the "Evaporator” circuit type. air conditioning, made from the sheets as mentioned above.
- RAS charge air cooler
- CAC Charge air cooler
- Evaporator heat exchanger of the "Evaporator” circuit type.
- FIG. 1 represents a soldering sheet of the prior art with three layers, the core sheet bearing the mark 2 and the brazing alloy (also called the plating layer), present on each of the faces of the core. , the reference 1.
- FIG. 2 diagrammatically represents a disruptive tube 1, a fin or a spacer (not shown, outside the tube) which can be assembled on the external face of the tube by brazing.
- the disrupter is assembled on the inner face of the tube by soldering.
- the two faces of the tubes are coated with a material called brazing or plating generally of the AA4xxxx series (reference 2 in the figure).
- FIG. 3 diagrammatically represents the brazing sheet used for the tube of FIG. 2, but in which intermediate cladding has been inserted between the core alloy of the tube and its brazing alloy inner lining of the AA4xxx series.
- FIG. 5 presents the results of rolling tests on multilayer materials with different intermediate layers: AA1050, AA3003 and two alloys according to the invention, "B” of test B and “C” of test C of the "Examples” chapter. ".
- 0 corresponds to a satisfactory plating, which may include some defects in the beginning and end of the composite material's plating.
- FIG. 6 shows the diagram of the test cycle developed specifically by the Applicant to reproduce the particular conditions of corrosion of the RAS (charge air coolers) and produced in a climatic chamber at a temperature of 50 ° C.
- RAS charge air coolers
- the invention consists in a judicious choice of the alloy of the intermediate plating (or layer) and, for the core, of the type of alloy, that is to say the AA3xxx series, and of its metallurgical state, for the realization of a brazing sheet of the "multilayer" type, adapted to the severe corrosion conditions that these materials undergo in service, in particular charge air coolers (RAS or CAC) or cabin air-conditioning evaporators.
- RAS charge air coolers
- CAC cabin air-conditioning evaporators
- the core is alloy of the series AA3xxx (typically 3915 or 3916) having undergone, after casting of the plate and before rolling, a homogenization at a temperature of 550 to 630 ° C for at least one hour
- the brazing alloy veneer is of the AA4xxx series (typically 4045 or 4343)
- the intermediate plating alloy is an aluminum alloy comprising 0.35 to 1.8% manganese, less than 0.3% in each of the other elements and less than 1% in total of said other elements, remains aluminum, such as in particular according to the preferred composition given in Table 1.
- Fe is generally an impurity for aluminum; the iron phases are preferred sites for initiation of pitting corrosion. As a result, its content must be less than 0.3% and more preferably 0.2%.
- Cu also increases the corrosion potential thus reducing the sacrificial anode effect.
- it can also increase the risk of galvanic corrosion and can promote intergranular corrosion by the presence of Al 2 Cu type phases at grain boundaries in particular. Therefore, its content must be limited to that of an impurity, less than 0.05%, in order to avoid phenomena of dissolution and re-precipitation of copper on the surface.
- Mn is a hardening element; it has a positive effect on post-soldering resistance by hardening in solid solution and in the form of fine precipitates. But above all, it improves the hot flow stress of the alloy (see Figure 4) greatly facilitating the bonding. Below 0.35%, this effect is insufficient. On the other hand, above 1.8 or even 1.7%, it gives rise to the formation of coarse intermetallic phases which are very unfavorable to the flowability of the alloy. A good compromise is between 0.35 and 1.4%, better between 0.5 and 0.9% and is optimized between 0.6 and 0.9%.
- Mg has a positive influence on mechanical strength, but it is detrimental to solderability, as it migrates to the surface of the veneer and, especially in the case of "CAB” brazing of the "Nocolok ® " type, forming a oxide layer which modifies in an unfavorable direction the properties of the solder.For this reason, and for such difficult applications, its content must be limited to 0.02% or even 0.01%, according to patent EP 1075935 Bl of the plaintiff.
- Ni and Co just like iron, have a negative effect on the resistance to corrosion, but also to bending. As a result, their content must be reduced to that of an impurity.
- Ti can be added up to a content of 0.15% because it has a slight curing effect, but also, it improves the corrosion behavior of the alloy, the titanium concentrating on layers parallel to the rolling direction, which promotes lateral corrosion rather than pitting corrosion.
- a plating layer of AA4xxx series alloy can be coated directly with AA4xxx series alloy plating, but an advantageous variant of this configuration is a symmetrical multi-ply composite material, that is to say provided with a veneer intermediate on both sides of the core, one ensuring the resistance to internal corrosion and the other to external corrosion, as this is particularly favorable especially in the case of the application to exchangers of the type "RAS".
- the core sheet after soldering it has a recrystallized structure with elongated grains, that is to say having a form factor F (maximum length / maximum width) greater than 2.
- the presence of anti-recrystallizing elements of the Cr, V, Zr and Se type is controlled and limited and the plate for the manufacture of the core sheet undergoes, after casting and peeling, and before rolling, homogenization at a temperature of 550 to 630 ° C for at least one hour.
- the assembly is hot rolled to a thickness typically of 3 mm and then cold to a thickness typically of 0.2 to 1.2 mm.
- brazing sheet is in the state known to those skilled in the art under the name of state" H18 ".
- brazing sheets are thus particularly suitable for the manufacture of charge air coolers (RAS or CAC) or cabin air-conditioning evaporators, in particular because of a good behavior when stamping, and also because the Brazed assemblies made from these strips have a non-perforating life of the core sheet at the SWAAT test of at least 8 weeks. They also exhibit significantly improved corrosion behavior in the operating conditions of a charge air cooler or RAS, in an acid medium, as reproduced by the test described in the "Examples" chapter on page 16.
- the invention consists in the best compromise to date possible between rolling ability and corrosion resistance. It differs from the prior art known by this recrystallized structure with elongated grains and by the addition of manganese to harden the alloy of the intermediate layer, while maintaining a minimum level of impurities contributing to good corrosion resistance .
- AA3916 alloy had the following composition (% by weight):
- AA4343 alloy had the following composition (% by weight): If: 7.2 Fe: 0.15 Cu: ⁇ 0.1 Mn: ⁇ 0.1 Ti: ⁇ 0.05 other elements ⁇ 0.05 each and 0.15 in total, remaining aluminum,
- the alloys A, B and C, for intermediate plating layer according to the invention had the compositions as in Table 2 below (% by weight):
- a spraying phase (similar to a salt spray) of the synthetic condensate followed by a drying phase and then a phase of exposure to humidity (% RH> 95).
- the condensate spraying phase is followed by a "flushing" phase (evacuation of the remaining condensate mist) and rinsing of the walls of the enclosure.
- the duration of exposure was fixed at 6 weeks.
- the synthetic condensate was composed of a mixture of nitric acid and sulfuric acid with added chlorides.
- the sections optical metallograms (L x TC direction) were performed.
- Sectional micrographs (L x TC direction) were then made. They confirm a localization of the initiation of corrosion at the level of the eutectic needles resulting from the re-solidification during the brazing cycle and then the propagation and lateralization of the corrosion in the intermediate cladding layer which plays its sacrificial role while we note the absence of perforation of the underlying soul. At most, the few penetrations observed at the core level do not exceed 30% of the thickness in the case of the configurations A & B and 50% of the thickness in the case of the configuration C after 8 weeks of exposure. This behavior is better than, or at least equivalent to, that observed in the case of an AA3003 type intermediate plating for which corrosion affects up to 50% of the thickness of the product.
