Use of Ni/sub x/Si/sub y/ as an interlayer for wear and corrosion resistance

Sputtered carbon/Ni/sub x/Si/sub y/ overcoats as thin as 50 /spl Aring/ are shown to be effective at providing both wear and corrosion resistance for magnetic hard disks. This paper will explore, through the results of an XPS study of the carbon/Ni/sub x/Si/sub y/ interface, the mechanism of how Ni/sub x/Si/sub y/ provides improved reliability.
