Abstract: This invention relates to cemented carbide articles that are characterized by substantially improved biocompatibility with human skin, tissue, organs, etc., compared with articles made from conventional cemented carbides. The essential feature of these improved biocompatible cemented carbide articles is a binder-depleted zone at and near the exposed surfaces of the articles. By depleting the binder (which mainly consists of Co and/or Ni, as well as their alloys) at and near the surface, the toxic effects of Co and Ni (known carcinogens), as well as the allergic reactions that these metals can cause when in contact with human skin, are eliminated. By depleting the binder only at and near the surface, the bulk properties of the cemented carbide article are not compromised or altered in any manner.
