摘要:
A high-energy treated cutter comprising a substrate having a top surface, an outer region, and an inner core and a wear resistant layer coupled to the top surface. The high-energy treatment alters the substrate's physical properties so that the inner core provides greater toughness and the outer region provides greater hardness, and greater abrasion resistance. The layer is protected prior to commencement of the treatment. In one embodiment, a cover is positioned to surround the layer and then the cutter undergoes treatment, wherein the cutter is subjected to impact forces with other cutters. In another embodiment, the cutter is positioned within a recess formed in a tray table, thereby providing protection to the layer. The cutter is secured in place via vacuum, glue, or weight. A spray nozzle applies shot material directed to the substrate of the cutter, thereby applying the impact forces to alter the substrate's properties.
