Abstract :
The tribological properties of the carbon nitride (CNx) coated CoPt-SiO2 granular films, especially the adhesion at the overcoat/magnetic layer interface, have been studied. Nanoscratch experiments and complementary scanning electron microscope (SEM) observations indicate that CNx adheres more strongly to the SiO2 matrix than to the CoPt granules resulting in enhanced adhesion at the interface as a function of the SiO2 content in the CoPt-SiO2 layer
