Abstract

A new diamond deposition process utilizing a plasma and a variety of interactions from a multiple laser system has been demonstrated, with WC/Co substrates. The process is conducted in open air and does not involve hydrogen. Structural characterization of the diamond coatings, which have exceptional adhesion to cutting tool inserts, indicates a cubic diamond structure. Tungsten and cobalt atoms are incorporated into the film and a layer depleted in cobalt exists at the diamond-WC/Co interface. Electron field emission current densities, useful for flat panel displays of 6 mA/cm2 at an applied voltage of 3000 V for a film-anode distance of 20 μm has been measured.
