The strength of the bonding interface between brass coated steel cord and rubber compound is one of the most important factors governing the performance and durability of car and truck tyres. Therefore, it is necessary to achieve a high level of adhesion and sustain this level throughout the service history of the tyre. Interfacial strength is closely related to the structure of the bonding layer and any changes brought about during the lifetime of a tyre. The structure of a tyre cord interface has been investigates by novel electron microscopic methods, mote traditional X ray Photoelectron Spectroscopy (XPS) profiling and X ray diffraction techniques to reveal the morphology before and after ageing. Fine ion beam etching of a tyre cord previously embedded in a belt compound created specimens thin enough to visualise the bonding layer structure in the electron microscope. More importantly, it was possible to examine the effect that cobalt adhesion promoters had upon the interface morphology as the suppressed the growth of crystalline dendrites normally associated with the ageing process. XPS profiling of the interface revealed that different types of adhesion promoter influenced the amount and distribution of cobalt ions in the bonding layer. Such techniques coupled with X ray diffraction also demonstrated the influence that cobalt had upon the structure of the interface and the subsequent crystallinity.
