| Abstract: | PcBN is the best cutting tool material for processing ferrous metal materials and realizing the high efficiency, fast speed and good precision in processing field with its well thermal stability, good chemical inertia and high hardness. The paper aims to summarize the behavior laws of different adhesives during the sintering course of PcBN under high temperature and high pressure, and wishes to further guide us to search for better composition and proportion for adhesive. Besides, it has also made the sintering mechanism of PeBN under high pressure known to us so that we can manufacture PeBN cutting tool material with high performance. |
