Special Issue Information

Dear Colleagues,

Adhesive bonding is a joining technology whose application is continuously increasing in several industrial fields. This is due to the several benefits it can bring, for example, assembly lightweight, even stress distribution, improved aesthetics and, often, the capability to connect different materials together.

However, adhesive bonding works via surface action and an effective interaction between the adhesive and the substrate is required to ensure adequate bond strength. The complexity of this issue is increased by considering the different chemical nature of substrates and the technological aspects that a wide range of materials to be connected can bring.

In this context, several methods have been developed in recent years to improve the strength of the interface between the adhesive and the substrate, and new ideas and solutions are continuously being generated.

The aim of this Special Issue is therefore to collect the latest scientific studies exploring methods and technologies to improve the strength at the interface. Experimental studies describing innovations in the application of chemical or physical treatments developed to toughen the interfaces of adhesive bonded joints are encouraged, as well as papers illustrating new strategies to modify the surface morphology (from the nano to the meso scale) and chemistry in order to increase the joints’ strength and durability under typical working conditions. Additionally, review papers on these topics are welcome.

Adhesive bonding has proven to be a reliable method of joining materials, and the development of new adhesives has made it possible to use bonding in a variety of applications. This article addresses the challenges of bonding metals such as the aluminum alloy EN AW-5754 and the stainless steel X5CrNi18-10. In this study, the effects of laser cleaning and texturing on the surface properties and strength of two bonded joints were investigated and compared with mechanical preparation (hand sanding with Scotch-Brite and P180 sandpaper). The bonded joints were tested with three different epoxy adhesives. During the tests, the adhesion properties of the bonded surface were determined by measuring the contact angle and assessing the wettability, the surface roughness parameters for the different surface preparations, and the mechanical properties (tensile lap-shear strength). Based on the strength test results, it was found that bonded joints made of stainless steel had 16% to 40% higher strength than aluminum alloys when using the same adhesive and surface preparation. Laser cleaning resulted in maximum shear strength of the aluminum alloy bond, while the most suitable surface preparation for both materials was preparation with P180 sandpaper for all adhesives.
