Abstract
Wear resistant cutting tools are comprised of cutting tools implanted with at least one element selected from the group consisting of, chlorine, fluorine, bromine, iodine, sulfur, indium, gallium and tin. The elements are implanted within the cutting tools in at least an effective amount to increase the wear resistance of the insert, up to an amount that does not substantially impair the hot hardness and toughness of the tool. In a method for lubricating the interface between a cutting tool and a workpiece in a lathe turning operation, at least one element selected from the group consisting of fluorine, bromine, iodine, sulfur, indium, gallium and tin are implanted in the tool. The elements are implanted so that the elements can lubricate the interface between the cutting edge and workpiece during turning without substantially impairing the hot hardness and toughness of the cutting tool. A workpiece is then shaped with the tool by metal removal, within a range of cutting speeds that cause the implanted element or elements to lubricate the interface.
