摘　　要：对模具的服役工况及适合的表面强化方式进行了分析,指出了渗硼是提高模具表面性能的有效方法,综述了目前模具工业中渗硼工艺国内外研究现状,指出了渗硼今后的研究发展方向。The latest progress in the fields of service condition of die and the surface modification and strengthening for die working surface was tentatively reviewed in a thought provoking way. The preliminary results show that the boriding technology is an effective method for improving hot-forging die life. The discussion centered on the state-of the-art synthesis technologies of the improvement of toughness for boriding layer fabricated by boriding methods, the intensively studied subjects of basic interest, and the development trends.
