Adhesive Joining Technology of Metalsand Role of Surface Condition

Abstract

Adhesive joining is currently being focused on as a key joining technology for industrial application like

architecture, aircraft and automotive, because it provides fruitful benefits for joint design such as dissimilar

material joining, crash energy adsorption improvement, and protection from galvanic corrosion. In the case of

adhesion of metals, however, its adhesion strength and stability strongly depend on metal surface condition,

like oxide layer thickness, chemical state or adsorbate; and they often cause problems or failure of adhesion.

This review briefly summarizes a series of studies of adhesive joining technology of metals in several topics;

merit of adhesive application for joining, surface condition and preparation method of metals for adhesion,

analytical method and knowledge of metal surface and adhesion interface.
