The cemented carbide is formed by powder metallurgy, heated under vacuum, and undergoes the vacuum dewaxing sintering process, which is beneficial to remove impurities, improve the purity of the sintering atmosphere, improve the wettability of the binder phase, promote the reaction, and finally form a compact with a certain chemical The composition and physical and mechanical properties of the structure of cemented carbide.
