The Role of Surface and Bulk Characterization in the Evaluation of Adhesive Joints

  • W. L. Baun


Adhesive joints are often evaluated by a mechanical test followed by exposure of a similar joint to elevated temperature, humidity, and/or corrosive atmosphere. After this exposure to a deleterious atmosphere, the bonded joint is usually tested again using the same geometry and conditions. The original load to failure is usually taken as a measure of the quality of the joint and performance during the accelerated test determines how well the joint will hold up in service. In the past only these numerical values were noted and there was little diagnostic work on the failure surfaces. More recently, however, there has been greater emphasis on where and why a failure took place. In order to fully evaluate failure surfaces it is necessary to determine the locus of failure. Often this task requires modern methods of surface characterization, especially when the failure takes place along a weak boundary layer (WBL). These surface characterization probes use beams of ions, electrons or photons and include ISS, SIMS, AES, and XPS. Examples of the use of these techniques along with microscopy are shown for adhesive bonding research on aluminum, titanium and steel.
