Definitions
- the present invention relates to a method for materially joining an aluminum casting component with a joining partner as well as the use of a pulsed laser system. Moreover, the present invention also relates to a component which comprises an aluminum casting component and a joining partner, which are connected to one another in a material-locking manner.
- the surface treatment includes chemical pickling, passivation of the surfaces, and the provision of cathodic dip painting.
- the processes used are predominantly of a chemical nature and thus burden both the environment and the health of the persons involved in the process.
- these surface treatment processes are logistical and process-technically complex and entail high operating and maintenance costs.
- the object is achieved by a method for cohesive bonding of a cast aluminum component with a joining partner, in which a pulsed laser system is used.
- the method according to the invention comprises a step of laser-treating a region of the cast aluminum component to be joined with the joining partner, wherein a pulse duration of the pulsed laser system is 100 to 200 ns and a pulse frequency of 10 to 80 kHz.
- the method may also provide several laser treatment steps, provided that at least one of these steps, in particular the last laser treatment step, is performed by means of a pulsed laser system with a pulse duration of 100 to 200 ns and a pulse frequency of 10 to 80 kHz.
- the joining partner is not limited in detail and may consist of any materials, in particular of metallic materials, such as. Steel or aluminum or a metallic alloy. Alternatively, plastics or fiber composites may be used as the material for the joining partner.
- Adhesive strength of the joint area leads to the material bond. Further, treatment with the pulsed laser system allows for conversion of the edge regions of the aluminum casting substrate, thereby providing the

- Radiation source a cooling device for the radiation source, a guide fiber from the radiation source to a scanner and just a scanner (for
- Device for example, on a robot, can be arranged.
- the integral connection of the aluminum casting component with the joining partner is carried out after the laser treatment without further treatment of the region of the aluminum casting component to be joined with the joining partner. This allows the process times and the logistic
- the pulse frequency is 10 to 40 kHz and in particular 10 to 30 kHz.
- Pulse duration is 120 to 160 ns and in particular about 150 ns.
- a wavelength of the laser system of 800 to 1200 nm has been found to be particularly advantageous since the pulse waves are so well absorbed and implemented by the aluminum material.
- the wavelength is 1064 nm.
- a beam diameter of 500 to 1000 ⁇ has proven to be advantageous.
- an average laser power of the pulsed system is adjusted so that it is 700 to 1000 W. This allows the
- Aluminum casting components are particularly efficiently avoided.
- the cohesive bonding of the aluminum casting component to the joining partner subsequent to the treatment with the pulsed laser system is not limited in detail.
- inventive method when combined with an adhesive process highlighted.
- the adhesives commonly used adhere particularly well to the laser-treated, modified surface topology of the region of the cast aluminum component to be joined.
- the aluminum material used according to the method according to the invention is not limited in detail, as long as aluminum makes up the majority in mass%, based on the total weight of the cast aluminum component.
- Joining partner to be joined aluminum casting component at least 70% by weight, based on the total weight of the cast aluminum component.
- the present invention also relates to a component.
- the component comprises an aluminum casting component and a joining partner and is produced by the method described above. By modifying the surface morphology and surface topology of the aluminum cast component by means of the specific laser treatment, the joining area was optimized and the cohesive bond to the intended join partner was improved.
- Figure 1 is a schematic representation for illustrating the
- Figure 1 illustrates the laser treatment of a
- Aluminum casting component 2 by means of a pulsed laser system. 1
- Laser treatment is provided according to the invention in order to pretreat the surface topology and surface tension of the cast aluminum component 2 in such a way that the adhesion to a joining partner during the subsequent step of integrally bonding the laser treatment to the laser treatment
- Aluminum casting 2 is increased with the joining partner and thus the adhesion between the cohesively joined workpieces is high. This favors a high durability of the joint connection.
- the aluminum material for the aluminum casting component 2 is preferably an aluminum alloy having an aluminum content of at least 70
- the laser system 1 transmits pulsed waves (indicated in FIG. 1 by hv) to a region 3 of the aluminum casting component 2 to be connected to the joining partner with a pulse duration of 100 to 200 ns and a pulse frequency of 10 to 80 kHz off. This causes several times a very high and extremely short-acting amount of energy on intended areas of the
- Aluminiumgussbauteils 2 which change the surface properties of the treated portion of the cast aluminum component 2 and for a
- the pulsed laser light with its high energy density can be focused in a targeted manner and applied to specific regions, from which point geometries 4 with point-to-point overlap and, depending on the intended configuration of the joining region
