Abstract
The article critically reviews about adhesives and their various adhesion phenomenons along with their categorization and functions. Benefit and drawbacks of adhesives joining was explained. Requirements for excellent bonding which includes, appropriate selection of adhesive, superior design for joining, surface cleansing, wetting were defined. The review clearly indicates the various theories involved in adhesion are namely mechanical interlocking, electrostatic, diffusion, wetting, chemical bonding, and weak boundary layer. Bond failure modes and their mechanism were elaborated briefly.
Highlights
A material which is used to the articles surfaces for their eternal joint is called an “adhesive” and the process being used is called “adhesive bonding”
Adhesion [2] is a condition in which two singular specimen are bonded to each other via seal contact interfacially such as mechanical forces caused due to chemical bonding or/and electrostatic attraction and van der Waals forces
A larger area is provided by adhesive bonding for overall stress transfer, which causes decline in the concentration of stress in the compact region
Summary
A material which is used to the articles surfaces for their eternal joint is called an “adhesive” and the process being used is called “adhesive bonding”. A material competent to form bonds between two parts where final entity made of two reciprocally joints sections is called adhesive [1]. Adhesion [2] is a condition in which two singular specimen are bonded to each other via seal contact interfacially such as mechanical forces caused due to chemical bonding or/and electrostatic attraction and van der Waals forces. The system strength is determined by the interfacial forces as well as by the mechanical behavior of interfacial zone and two different phases of huge mass. There are two principal adhesive bonding arises viz: structural and non-structural
