Abstract

Razor blades are coated on the cutting edge, immediately below a coating of hydrocarbon polymer, with a metallic coating consisting of 50 atom-gm% of Ir or an alloy of In and Pt, of a thickness, pref. of 50-600 angstroms, and contg. pref. 70 atom-gm% of In. The polymer is pref. polyethylene. The Ir improves adhesion of the polymers and accelerates its hardening. The razor bladeshave improved length of service.
