2) The quality stability is not high, the self-propagating reaction process is fast, the heat loss can be different due to the advancing of combustion waves, an unbalanced phase or a metastable phase can appear in the combustion process, and the sintering is easy.
3) The efficiency is lower, and the early stage needs evenly to spread self-propagating reaction powder, and after the anchor clamps tighten, 50mm interval just needs to carry out the pin-stirring friction spot welding, and self-propagating reaction powder is from being ignited to self-propagating reaction completion in-process, and the pin-stirring is inserted in metal and carbon fiber material all the time, and the holding time that the pin-stirring inserted metal needs 3s-15s time, and whole process inefficiency, for a long time.

However, in this technique, the sprayed layer formed of the metal material is melted only with the surface of the metal member, resulting in poor bonding strength of the metal member and the sprayed layer.

According to the scheme of the invention, the metal coating is formed on the surface of the resin material, the lower surface of the metal material is attached to the upper surface of the metal coating, and then the metal material and the metal coating are welded together by utilizing a laser welding technology, so that the metal material and the resin material are bonded together. This method breaks through the technical prejudice that the conventional method, namely, the method which is already formed to some extent, namely, the surface treatment is carried out on one side of the metal material to finish the bonding of the resin material and the metal material, so that the method has a breakthrough progress. The method of the invention carries out plating treatment on the side of the resin material, and the penetration of the welding part is more than or equal to the sum of half of the thickness of the metal coating and the thickness of the metal material, namely, the welding part is a metal coating which penetrates through the metal material and at least reaches half of the thickness, and as the metal coating is bonded with the resin material, the welding part penetrates through the metal coating so as to bond the metal material with the metal coating, thereby bonding the metal material with the resin material. The laser welding technology has the advantages of very high speed, very high efficiency and very stable quality, and is suitable for large-scale production.
The following is a detailed description of specific embodiments:
embodiment one:
the preparation method in the first embodiment includes the steps S100 to S400. Fig. 2 is a schematic structural view showing a dissimilar material joint of a resin material and a metal material according to a first embodiment of the present invention. As shown in fig. 2, the dissimilar material joint produced by steps S100 to S400 includes a resin material 1, a metal material 3, and a metal coating 2 connected between the resin material 1 and the metal material 3.
In step S100, the resin material 1 may be selected from thermoplastic resin and thermosetting resin, and may be, for example, a carbon fiber composite resin material 1. The resin material 1 may have a plate shape, and the thickness thereof is not limited. The resin material 1 may be, for example, a thermoplastic resin or a thermosetting resin, and may be, for example, a carbon fiber resin material 1.
In step S200, the material of the fine metal particles may be selected from a metal material capable of solid phase bonding with the metal material 3, preferably a metal material homologous to the metal material 3, for example, an aluminum alloy material is used as the material of the metal material 3, and the material of the fine metal particles may be an aluminum alloy material or another aluminum alloy. The material of the metal material 3 is a ferrous alloy material, and the material of the fine metal particles may be a ferrous alloy material or another ferrous alloy material. The material of the metal material 3 is a nickel alloy material, and the material of the fine metal particles is another nickel alloy material.
In this embodiment, fine metal particles are sprayed on the upper surface of the resin material 1 by a cladding method. The cladding method is selected from cladding spraying methods capable of generating a high-temperature gas, and may be, for example, plasma spraying, arc spraying, or the like. The thickness of the metal coating 2 is any value in the range of 0.2mm-5mm, for example 0.2mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm.
By using the cladding spraying method, the temperature of the fine metal particles is increased in the spraying process, the fine metal particles are easy to deform, and the particles deform into a flat shape under the spraying impact, so that a large contact area is obtained between the resin material 1 and the fine metal particles, and the adhesion strength is further improved. It will be appreciated that the fine metal particles will not deform as long as they are deformed at elevated temperatures and impact forces during spraying, and that the fine metal particles will not deform readily at lower temperatures or without impact forces. Therefore, fine metal particles are sprayed on the upper surface of the resin material 1 by the cladding method, so that the resin material 1 and the metal coating layer 2 can be very tightly bonded, and the bonding strength between them is very high.
In step S300, "adhesion" means that the metal material 3 and the metal coating 2 are in contact with each other and in close contact with each other. The thickness of the metal material 3 is not particularly limited, but in order to be able to closely adhere to the metal coating layer 2, the metal material 3 may have an optimal thickness range of 0mm or more and 2mm or less, for example, 0.2mm, 0.5mm, 0.8mm, 1.2mm, 1.5mm, 1.8mm, or 2mm. And the shape of the metal material 3 is preferably a plate shape.
In the step S400, laser is injected from above the metal material 3 toward the metal material 3, and a welded portion 4 may be formed on the metal material 3 and the metal coating 2, where the welded portion 4 extends downward from the upper surface of the metal material 3 into the metal coating 2, and the thickness of the welded portion 4 is the penetration, and in a preferred embodiment, the penetration of the welded portion 4 is equal to the sum of the thickness of the metal material 3 and the thickness of the metal coating 2. That is, the welded portion 4 extends from the upper surface of the metal material 3 to the lower surface of the metal coating 2. Here, it should be noted that the lower end of the welded portion 4 may be located at the interface between the metal coating 2 and the resin material 1, and optimally, at the lowest end of the metal coating 2 without breaking through the lowest end of the metal coating 2, i.e., without touching the resin material 1, so that the thermal influence of the resin material 1 can be minimized to the maximum extent to prevent the bonding strength with the metal coating 2 from being affected, while the bonding strength of the obtained dissimilar material bonding member is maximized.
The shape of the weld of the laser welding technique may be one or a combination of several of a straight line, a circle, a C-shape, a spiral shape, an unsealed ring shape, a wave shape, a rectangle, an S-shape and a diamond shape as shown in fig. 3. The shape of the weld also affects the joining strength of the dissimilar material joint, and for a dissimilar material joint having high joining strength, the shape of the weld is preferably selected.
In order to minimize the thermal influence of the resin material 1, it is necessary to select the optimum welding conditions. In general, the welding conditions are affected by the materials, shapes, and the like of the resin material 1 and the metal material 3, and thus, the materials, shapes, and the like of the resin material 1 and the metal material 3 are different, and the optimum welding conditions corresponding thereto are also different. The welding conditions include a heat source, an output power, a welding speed, a welding power, a diameter of the welding portion 4, and a gap between the metal coating 2 and the metal material 3, for example, the welding speed is 60 to 120mm/s, the welding power is 3.75 to 5kW, an upper limit of the pinch pressure of the laser welder is 2.5 to 3bar, and a lower limit is 1.5 to 4bar.
In particular, the present invention further provides a dissimilar material joint piece, which is prepared by the above preparation method, and features of the dissimilar material joint piece correspond to features introduced in the above preparation method one by one, and are not described herein again.
In particular, the present invention also provides a vehicle including a target member configured from the dissimilar material joint member described above. The target member may be any structural member that can be used in the vehicle manufacturing process, such as a mechanical product used for an outer panel of a vehicle, a structural member for interior and exterior decoration, a control system, a drive system, and the like.
The dissimilar material joint material can be applied to a product in which a resin material 1 and a high-strength metal material 3 are combined, which is excellent in productivity and innovation, such as a civil engineering field, a household electrical appliance field, and a construction field, in addition to a vehicle.
Embodiment two:
the difference between the second embodiment and the first embodiment is that the specific steps in step S200 are different, that is, the finally prepared metal coating 2 is different, and the structure of the dissimilar material joint element finally caused is also changed accordingly. As shown in fig. 4, in this embodiment, the step S200 includes a first metal film layer 21 forming step and a second metal film layer 22 forming step. The first metal film layer 21 is formed by spraying first fine metal particles on the upper surface of the resin material 1 by a cladding method to form the first metal film layer 21 on the upper surface of the resin material 1. The second metal film layer 22 is formed by spraying second fine metal particles on the upper surface of the first metal film layer 21 by cold spraying to form the second metal film layer 22 on the upper surface of the resin material 1. The metal coating 2 comprises a first metal film layer 21 and a second metal film layer 22. The thickness of each of the first metal film layer 21 and the second metal film layer 22 is any one of a thickness in a range of more than 0.2mm and less than 1.5mm, and may be, for example, 0.2mm, 0.5mm, 1mm, 1.2mm, or 1.5mm.
In this embodiment, the second metal film layer 22 is sprayed using a cold spray method, such as a supersonic cold spray method, which is operated at a high speed above sonic velocity. It is understood that in the cold spraying method, the second fine metal particles are not easily deformed, and thus, a thick film is easily formed on the surface of the first metal film layer 21, and the thick film is more easily closely bonded to the metal material 3 than the thin film. The second fine metal particles are preferably formed on the upper surface of the first metal film layer 21, and are not preferably formed directly on the upper surface of the resin material 1, because the second metal film layer 22 is formed by spraying using a cold spraying method in which the temperature is low, the second fine metal particles are not easily deformed, and if the resin is soft, the second fine metal particles are not easily deformed when the second fine metal particles are sprayed on the upper surface of the resin material 1, and the bonding between the second fine metal particles and the resin material 1 is not tight, and the formed second metal film layer 22 is easily detached from the upper surface of the resin material 1. Therefore, the second metal film layer 22 is not suitable to be directly formed on the upper surface of the resin material 1. Since the second metal film layer 22 and the first metal film layer 21 are made of materials similar to the metal materials, the second metal film layer 22 is more suitable for being formed on the first metal film layer 21 when the two materials are bonded together. The first metal film layer 21 can be tightly bonded to the resin material 1, but since the first metal film layer 21 is not easily formed into a thick film, it cannot be tightly bonded to the metal material 3, and the second metal film layer 22 exactly compensates for this defect.
Therefore, in the embodiment of the present invention, the first metal film layer 21 can be bonded to the resin material 1 very well, the second metal film layer 22 can be bonded to the first metal film layer 21 tightly, and the second metal film layer 22 can be bonded to the metal material 3 better because a thick film is easily formed, so that the first metal film layer 21 and the second metal film layer 22 complement each other, and finally the bonding strength of the resin material 1 and the metal material 3 can be very high.
Embodiment III:
the difference between the third embodiment and the second embodiment is that in the third embodiment, the specific steps in the step S200 are different, that is, the finally prepared metal coating 2 is different, and the structure of the dissimilar material joint element which is finally caused is also changed accordingly. In this embodiment, the step S200 includes a second metal film layer forming step repeatedly performed, and the finally prepared metal coating layer 2 includes a first metal film layer 21 and a plurality of second metal film layers 22 formed on the first metal film layer 21. For example, there may be two second metal film layers 22, three second metal film layers 22, four second metal film layers 22, or more second metal film layers 22. In this way, the thickness of the first metal film layer 21 and the second metal film layer 22 is thicker than those of the first metal film layer 21 and the second metal film layer 22 in the second embodiment, and the finally formed metal coating 2 can be bonded with the metal material 3 better.
Embodiment four:
the fourth embodiment differs from the foregoing embodiment in that in the fourth embodiment, the dissimilar material joint member includes one layer of resin material 1 and two or more layers of metal materials 3, and the two or more layers of metal materials 3 are adjacently disposed.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations or modifications that are consistent with the general principles of the invention may be directly determined or derived from the disclosure of the invention without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
