MECHANICAL FEATURES OF SYMTHETIC GLUE BONDING OF METALS WITH CERAMIC GLASS

Abstract

Adhesive bonding using synthetic materials has gained a wide field of use in the last decade, at bonding metal sheets or metal parts, non-metallic or combined, especially in light construction and precision mechanics, but also in vehicle manufacturing. Instead of metal layer or soldering alloy, a thin layer of adhesive is used, which after application tightens and takes external forces through the mechanical strength due to its mass cohesion and adhesion between the adhesive and the surfaces to be joined. Adhesive bonding is a process with broad application  worldwide. In many cases it replaces the classic combination (welding, riveting) and allows bonding of materials with different structures, as in the case studied (metal with glass). According to the mechanical theory connection bonding between the bearing surface and adhesive (or any coating, paint) are made by adhesive infiltration into the pores, asperities (roughness) of the bearing surface. However, this theory can not be generalized because a strong glued joint can be made in the case of smooth material (for example: glass, semiconductor silicon plates). A relatively new scientific branch deals with theoretical basis of the soldering technique, surface engineering(surface engineering, surface science).
