Abstract

A scalpel blade is made by depositing a coating onto a tapered region of a substrate which is tapered with an included angle of from about 10 to about 25 degrees to an edge. The substrate is made of surgical-grade stainless steel hardened to a Rockwell C hardness of at least 54 and then annealed to a Rockwell C hardness of from about 46 to less than about 53. The coating overlying the tapered region has a thickness of from about 0.1 to about 2.5 micrometers and includes a first coating layer of a first metal, and a second coating layer overlying the first coating layer. The first coating layer is preferably zirconium or a zirconium-base alloy, and the second coating layer is preferably zirconium nitride. The edge may be atomically sharpened by applying a large negative voltage to the substrate relative to the deposition source while a portion of the thickness of the second coating layer is being deposited.
