Graphene as a Protective Overcoat for Hard Disk Media
- 227 Downloads
Based on its remarkable mechanical, tribological and chemical properties, graphene is positioned as a material with great potential for countless applications in the future—especially for high strength, anti-wear and corrosion protection applications at the nanoscale. With this in mind, one of the possible applications for graphene could be as an ultrathin protective overcoat for commercial hard disk media. The advantage of using an atomically-thin overcoat of graphene is that it would lead to a drastic reduction in the head-media spacing and dramatically increase the areal density of hard disk drives. This chapter explores the use of single-layer graphene as a possible hard disk media overcoat.
