Abstract
Abstract
Innovative surface technology processes offer a wide range of surface preparation options, allowing engineers to make major changes to the properties of products. Surface modification can also improve the quality and the strength of the bond created by technologies such as bonding, painting, coating, sealing and other adhesion. By activating molecular groups on the surface, wetting properties can be improved, while altering the microtopography of the surface can create roughness and texture. Surface modification suitable for industrial conditions in cold plasma surface modification. The the wetting boundary angles are measured with ethylene glycol and distilled water, and the results are used to calculate the surface free energy of the modified surface in mN/m according to Fowkes surface free energy theory. The demonstration of adhesion improvement of specimens with good wetting surfaces should be carried out by a series of bonding experiments, showing the changes in strength due to surface treatment. In addition, the technical advantages obtained by modifying the topography can be characterised by examining the separated surfaces.
