Abstract
Of possible techniques for studying brass-rubber adhesion, the principal ones used in the present work are scanning electron microscopy (SEM), SEM with x-ray microanalysis (XRMA), Auger electron spectroscopy (AES) and Laser ionisation mass analysis (UMA). Results obtained with standard and phosphate-treated tyre cords indicate irregularities in surface composition of the wires in both cases. Furthermore, the surface composition of the brass is very different from the bulk composition. These phenomena may be related to the original production process for the wires and are shown to influence the rate of sulphidisation of the brass surface. The effects described will undoubtedly influence the strength of the adhesive bonding.
