Abstract:
A low friction top coat over a multilayer metal/ceramic bondcoat provides a conductive substrate, such as a rotary tool, with wear resistance and corrosion resistance. The top coat further provides low friction and anti-stickiness as well as high compressive stress. The high compressive stress provided by the top coat protects against degradation of the tool due to abrasion and torsional and cyclic fatigue. Substrate temperature is strictly controlled during the coating process to preserve the bulk properties of the substrate and the coating. The described coating process is particularly useful when applied to shape memory alloys.

Claim (Index 1):
A wear resistant coating for a cutting edge, comprising:\n a metal-ceramic coating comprising at least one pair of layers comprised of a ceramic layer overlaying a metallic layer, the metal-ceramic coating comprising a columnar structure and having a toughness of greater than about 0.05 H 3 /E 2 ; and at least one top coat overlaying the metal-ceramic coating, the at least one top coat comprising an amorphous matrix having a friction coefficient of less than 0.3; wherein the at least one top coat imposes a compressive stress of from about 0.1 to about 8 gigapascals to the underlaying metal-ceramic coating.
