Abstract

EN This chapter presents results concerning the influence of the sintering parameters on the hardness and structure of the Nano_WC-5Co nanocrystalline cemented carbides with Cr3C2 (0.3, 0.6 and 0.9%) growth inhibitor and without it. The cutting edges made of nanocrystalline cemented carbides were sintered using the Pulse Plasma Sintering (PPS) method. During the manufacturing process of cutting inserts, various values of both sintering temperature and sintering time were applied. Due to the pulse character of the PPS method and the phenomena accompanying the pulse process, pulse sintering allows for more efficient production of sintered tool material than conventional methods.
