METALLIC ARTICLE POSSESSING A BRIGHTLY COLORED SURFACE OF LOW REFLECTIVITY AND PROCESS FOR PRODUCING SUCH SURFACE

摘要

A metallic article, e.g., a surgical needle, possessesa multilayer coating exhibiting a brightly colored surface of lowreflectivity which increases the visibility of the articleagainst its background. A physical vapor deposition (PVD)procedure, e.g., a cathode sputtering technique, is used inapplying the coating to the metallic article.
