Abstract: In this paper, we studied the quenching and cryogenic treatment processes of WC-Co and founding tungsten carbide cemented carbide, and analyzed their microstructure and the cause of increased performance of these treatment as well as the mechanism of increased performance of these treatment. It isconformed that the microstructure of WC-Co cemented carbide isγ′and M7C3, M6C, W23C6carbide and founding tungsten carbide isηand M7C3, M6C, M23C6. The adhesive phase can be strengthened and the histology and the microstructure can be improved by quenching and cryogenic treatment.
Key words: roller bit, carbide insert, metallographic analysis, surfacing welding layer, cryogenic treatment
