Introduction
In the analysis of adhesion bonding, possessing knowledge of the composition and structure of the adhered surface is important. Characterization of bonding surfaces aids both in design and failure analysis of a bond, should the adhesion bond fail.
Surface analysis is the use of microscopic chemical and physical probes that give information about the surface region of a sample. The probed region may be the extreme top layer of atoms (the only true surface, for purists), or it may extend up to several microns (millionths of a meter) beneath the sample surface, depending on the technique used. Analysis provides information pertaining to chemical composition, level of trace impurities, and physical structure or appearance of the sampled region. Such information is important to researchers and manufacturers who must understand the materials in order to verify a theory or to create a better product.
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) involves the interaction of infrared radiation with matter. It covers a range of techniques, mostly based on absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify and study chemicals.
