Research on cubic boron nitride (PcBN) composites shows potential for improving cutting tool performance by incorporating microfibers made from refractory compounds.
The study focuses on creating two-layer composites reinforced with silicon carbide whiskers (SiCw) and aluminum oxide (AlO) microfibers to enhance stability during machining of hardened steels.
Tool-life tests demonstrate the effectiveness of these PcBN composites in cutting hardened KhVG steel under varying conditions, with various material properties analyzed for optimization.
