    • 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.
    • 耐磨切削刀具由植入有选自氯,氟,溴,碘,硫,铟,镓和锡中的至少一种元素的切削刀具组成。 这些元件以至少有效的量植入切削刀具内,以增加刀片的耐磨性,直到不显着地损害刀具的热硬度和韧性。 在车床旋转操作中用于润滑切削工具和工件之间的界面的方法中,从工具中注入选自氟,溴,碘,硫,铟,镓和锡中的至少一种元素。 这些元件被植入,使得元件可以在转动期间润滑切削刃和工件之间的界面而基本上不损害切削工具的热硬度和韧性。 然后,在切割速度范围内通过金属去除,通过工具对工件进行成形,从而使植入的元件润滑界面。
