摘要
The relative performance of ion-implanted and unimplanted machine tool taps, inserts, and punch-die sets was compared using blind tests. Performance of the tools, defined as the number of parts machined to within specifications, was evaluated under actual and simulated production conditions; relative performance was obtained by dividing the average performance of implanted tools by the average performance of unimplanted tools. The tools were implanted with a combination of 80 keV N+ and N2+. Implanted high speed steel taps exhibited performance by factors 1.5 to more than 4 as compared to unimplanted taps. Implanted TiN-coated metal cutting carbide inserts exhibited performance from factors of 2-4, and the performance factors of nitrogen-implanted punch-die sets ranged from 2.0 to 2.6.
