Bonding pre-treatment of metals
Adhesive joining is one of the most demanding joining technologies in the industry today. In addition to the qualified selection of suitable adhesives, cleaning and pre-treatment must also be carefully defined in order to ensure reproducible and process-reliable adhesion over the long term.
By removing oxide layers, the surfaces are cleaned in a way that is suitable for adhesive bonding. In addition, the parameters used especially in the cleanLASER process for processing light metals (especially aluminum and magnesium) in a single process step not only lead to cleaning, but also to modification of the component surface. This makes it possible to achieve extremely high corrosion stability and thus a long-term adhesive pre-treatment.
The roughness of the surface can be specifically adjusted for high and low viscosity adhesives.
