Application of Bonded Joints for Quantitative Analysis of Adhesion

Abstract

The performance of hot-dip coated steel sheets is associated with properties of the zinc coatings on steel substrate. For the characterization of the adhesion behaviour of zinc coating on steel various tests were employed. The study was focused on quantification assessment of galvanized coating adhesion to substrates. Methods for evaluation of the bonding strength of zinc coating by the shear strength and the T-peel tests applying four special types of adhesives were used. The experimental tests of bonded joints show that the adhesion of the zinc coating to the substrate was higher than that of the applied adhesive with the highest strength.

Adhesion of batch hot-dip galvanized components

“…The post-galvanizing processing of such galvanized steel sheet foresees typically the cutting of two-dimensional matrices out of the coil material with subsequent forming and joining, e.g., spot welding, clinching, and/or adhesive bonding. These techniques are in use in high-quality and high-quantity applications since long, e.g., automotive industries, white goods, and installation systems, thus, the processing steps are well investigated and state of the art [3][4][5][6][7][8].…”

“…Adhesive joining of substrates with zinc coatings, which are applied in the continuous hot-dip galvanizing process, is well known and state of the art in case of continuously galvanized material [6][7][8]. In contrary, the knowledge regarding the applicability of adhesives in case of batch galvanized components is very limited.…”
