Plasma treatment using nitrogen gas to improve bonding strength of adhesively bonded aluminum foam/aluminum composite

Evaluation of surface and bonding properties of cold rolled steel sheet pretreated by Ar/O2 atmospheric pressure plasma at room temperature

“…It indicates that surface treatment has to be needed for the application of structural adhesive in automotive construction. In recent studies, the surface treatment before applying adhesive on the adherends significantly affected the bonding strength and long-term durability of the adhesive joint (and Chung et al, 2007;Dartevelle et 2003; Kim et al, 2003;Tang et al, 2008). Surface treatment is a first step in adhesive bonding technology.…”

Application of Image Processing to Predict Compressive Behavior of Aluminum Foam

“…Metal foams are divided into open-cell and closed-cell types, depending on the shape of the cell in their structure. Accordingly, many studies have been carried out in order to understand the elastic modulus, tensile and compressive strength, buckling, and fracture behavior of various metal foams [7][8][9][10][11][12].…”

Effect of oxygen plasma treatment on the bonding strength of CFRP/aluminum foam composite

“…Indeed, a minority group of researchers have studied the technology of joining aluminum foam with other materials [13][14]. For example, Kitazono et al [13] studied the solid-state diffusion bonding of closed cell aluminum foams, showing that diffusion bonding is effective at high temperature conditions and that bonding strength can be improved by controlling the surfaces and atmosphere conditions necessary to minimize the stable oxide layer at the surface of aluminum foams.…”

Recently, we studied plasma treatment using nitrogen gas to improve bonding strength of adhesively bonded aluminum foam/aluminum composites [14]. In that study, we showed that when aluminum is plasma-treated using nitrogen gas, the bending and shear strength of aluminum foam/aluminum composites are increased by 13% and 30%, respectively, compared to the case without plasma treatment.…”
