Corrosion and corrosive wear are important failure mechanisms for new particulate media based on metal particles.
Particles are so small that even a slight amount of corrosion can lead to loss of data.
This research is aimed at understanding the fundamental mechanisms involved in the corrosion and degradation of flexible magnetic media. Ongoing collaborative research with Drs. XPS results indicate the existence of a strong chemical interaction between nitrogen from the polymer and the iron oxide surface which likely involve donation of electrons from the p system of the AQ polymer. XPS experiments on Cu and Al have shown very similar trends.
