Abstract

In this work, a review of the cemented carbides alloys of the WC–Co system is carried out. The cemented carbides of the WC–Co system are mass used in various industries, for example, as tools. The characteristic of materials is given depending on the size of structural components. The features of obtaining starting materials for obtaining a powder mixture are considered. Attention is paid to the features of compaction of powder mixtures and their subsequent sintering. The main problems arising in the preparation of fine-grained hard alloys are considered.
