Surface pre-processing techniques: Choice, testing, and benchmarking
To produce adhesive bonding joints, sufficient adhesion of the joined partners must be provided. To guarantee adhesion on real parts, surfaces must be pre-treated. In this process, adhesion is improved, and corrosion inhibiting coatings can be produced.
Competences and system technology
- Sandblasting and particle blasting in vacuum
- Coating sandblasting SACO® for silication of joining part surfaces
- Flame pyrolysis to apply coupling agent coatings or nanostructured SiOx coatings
- Atmospheric pressure – plasma processing for fine cleaning, activation and separation of coupling agent layers (plasma polymerization)
