SubstrateÕlayer interface of amorphous-carbon hard coatings
A combined study of the crystalline structure, the chemical interaction, and diffusion processes of the substrate/layer interface of amorphous-carbon hard coatings is presented. The structure of the coatings and their gradient layer interface to a chromium buffer layer has been investigated on two substrates @Si~100! and tool steel# using x-ray diffraction ~XRD!. Chemical interaction and diffus...
متن کاملProtective diamond-like carbon coatings for future optical storage disks
Diamond-like carbon (DLC) is a promising protective coating for future optical storage technologies. The requirements place conflicting constraints on the nature of the DLC. It must be transparent at 400 nm, hard and wear-resistant, uniform, pinhole-free, have a low stress and be deposited at high rate without a high heat load on a plastic substrate. In order to optimise the films under these c...
متن کاملDiamond-like carbon for magnetic storage disks
Diamond-like carbon films form a critical protective layer on magnetic hard disks and their reading heads. The ultimate limit to storage density is the super-paramagnetic limit, where the thermal energy is able to overcome the coercive energy of the magnetic bit. Perpendicular recording should allow storage densities up to ;1 Tbityinch . This requires the read head to approach 2 closer to the m...

15 صفحه اولCompositional depth profile analysis of coatings on hard disks by X-ray photoelectron spectroscopy and imaging
A hard disk medium is typically composed of several layers including the magnetic recording layer, a buffer layer, as well as a wear protective layer. In the work presented here, the hard disks analysed have a total of five layers with the uppermost layer being the lubricant. The second layer is diamond like coating and this is followed by the magnetic layer consisting of an alloy of cobalt and...
