Abstract

Coating properties and performance can be tailor-designed by proper control of nanostructure and process conditions. In this paper, we present two examples. The first example is the synthesis and optimization of one-nm-thick nitrogenated carbon (CNx) nanolayers as protective overcoats in extremely high density hard disk systems. The second example is the development of multilayer coatings for wear protection at elevated temperatures. Synthesis of these coatings was done by magnetron sputtering. These studies demonstrate that one can produce atomically smooth one-nm thick CNx overcoats with acceptable corrosion performance. In addition, we show that superhard coatings based on TiB2/TiC multilayers with high thermal stability, low internal stress and high wear resistance can be synthesized by proper choice of nanolayer thickness and process conditions.
