摘要
WC-Co cemented carbide is composed of the refractory metal compound WC and the bonding phase Co, which exhibits excellent overall performance and is therefore widely used in the manufacture of various cutting tools and wear-resistant components. However, the forming process of cemented carbide has received less attention due to its technical complexity and difficulty to improve, but the forming process, as an important part of cemented carbide preparation, plays a role in the transition from powder to sample, and the high density and homogeneity of the formed billet contributes to the subsequent sintering of the final cemented carbide product. The physical and mechanical properties of the final cemented carbide product are greatly promoted by the molding process. The article introduces the traditional WC-Co cemented carbide molding techniques such as injection molding, isostatic molding, and molding, and gives an overview of the latest research progress, focusing on the current situation of the application of 3D printing technology on WC-Co cemented carbide, which has emerged in recent years, and analyzes the advantages, disadvantages, and prospects of various molding techniques. ? 2023 Editorial Office of Chinese Journal of Mechanical Engineering.
